Olive oil provides 899 kcal per 100 g according to CREA. A 10 g serving provides about 90 kcal. A household tablespoon can hold very different amounts.
Extra virgin olive oil, regular olive oil and seed oils have similar calories because they are almost entirely fat. The nutritional difference lies mainly in the fatty acid composition and, above all, in the minor components, not in any big calorie saving. A handy rule of thumb? Multiply every gram of oil by 9, and you get roughly your calories!

Grams and millilitres are not the same
Oil is less dense than water: 10 ml does not weigh exactly 10 g. Household tablespoons and teaspoons are also not standardised and can be heaped or level. For a recipe, a consistent measure is often enough; for a meal plan you need a scale and the reference given by your professional.
Extra virgin and other oils
Switching oils does not automatically reduce calories. Extra virgin olive oil, obtained without refining, keeps its aromas and minor components and can deliver plenty of taste in a measured amount. What counts is the whole eating pattern: vegetables, grains, legumes, proteins and how often you have each portion.
How to measure it without waste
1. Pour into a tablespoon, or weigh the plate before and after.
2. Dress in a bowl to distribute the oil better.
3. Use an aromatic oil raw to get intensity with precision.
4. Do not pour straight from the tin onto a single portion.
5. Also count the oil absorbed by sauces and cooking.
Calories and quality are not synonyms
A high-calorie food is not automatically "bad", just as a small portion is not a cure. Olive oil is an energy-dense condiment within the Mediterranean diet. Suitable amounts depend on your energy needs, your health and the rest of your diet; for clinical goals, you need a professional.
How much a tablespoon really weighs
Weigh a bowl, zero the scale, add your usual tablespoon of oil and read the grams. Repeat three times: you will have the real average of your everyday gesture. This test shows why online estimates differ and lets you always use the same utensil without turning every meal into a calculation.
Seasoning and cooking
Oil added in the pan, in a marinade and raw adds up. Some may stay in the pot, but it is not prudent to assume it is automatically zero. For recipes you make often, weigh the total oil and divide it by the number of portions. In frying, however, absorption depends on the food and the technique and does not equal all the oil used.
Flavour as a measuring tool
An aromatic extra virgin olive oil, well distributed, can give an intense impression with a controlled dose. Emulsify it with lemon or vinegar to coat a salad; drizzle it over a soup; use a brush for baking trays. These are techniques of culinary precision, not promises of weight loss.
Reading the values correctly
The CREA figure of 899 kcal refers to 100 g and is rounded according to food composition methods. Labels may show slightly different values depending on the sample and rounding. For everyday use this difference is minimal; what matters most is not confusing a serving, a tablespoon and 100 grams.
Calories per gram, teaspoon and tablespoon
Oil is made almost entirely of fat and provides about nine kilocalories per gram. Nutrition tables often give the value per 100 grams, while in the kitchen we think in teaspoons, tablespoons or millilitres. The conversion depends on the real weight of the portion: a level tablespoon and a heaped one are not the same thing, and household utensils have different volumes. For an accurate estimate, weigh the oil on a kitchen scale instead of relying only on the shape of the spoon.
As a practical reference, a tablespoon commonly considered to be about 10 grams provides roughly 90 kcal; larger portions increase proportionally. The product label remains the specific reference. Do not confuse grams and millilitres: oil is less dense than water, so 10 ml does not weigh exactly 10 g. In everyday life extreme precision is not always necessary, but knowing the order of magnitude helps avoid repeated errors when you log condiments.
Create a personal table with three rows: teaspoon, tablespoon and your usual drizzle. Weigh each three times and note the average. Calculate the calories using the label value per gram. Keep the table on the fridge or in the app you use. There is no need to repeat the weighing every day, but redo it if you change utensil or bottle. This method removes most of the differences between online estimates and makes the portion understandable even to whoever cooks for the family.
Measuring your own real portion
Put a bowl on the scale, zero it and pour the oil as you normally do. Repeat three times and work out the average: you will discover how much your "drizzle" or your tablespoon really weighs. Then use the same utensil for a week. This exercise is not meant to obsessively control every meal, but to turn a vague measure into a conscious gesture. It is particularly useful in shared recipes, where a tablespoon can mean very different amounts between authors and kitchens.
To dress a salad you can weigh the total oil and divide by the number of people. For a baking tray, measure how much is added before and after cooking, without assuming that everything stays in the dish. Frying is different: you do not consume the whole amount used, and absorption varies with the food, temperature and technique. So avoid attributing to each portion all the calories of the oil in the pan or, conversely, treating them as zero. The method must follow the type of preparation.
For shared recipes, weigh the oil only once in the container and record how many real portions are served. If there are leftovers, update the division instead of using the theoretical number. In restaurants, standardised recipes and dispensers help consistency, but nutritional counting requires specific skills and rules. At home, the goal is an honest estimate. Counting a teaspoon perfectly while ignoring the sautéed base of the whole pot produces only apparent precision.
Energy density and nutritional quality
Saying that oil is high in calories does not mean it is nutritionally useless. Energy density describes how much energy an amount provides, while quality considers composition, role in the diet and the foods it replaces. Extra virgin olive oil used in place of fats rich in saturated fat can fit into a balanced eating pattern; adding it without reducing other energy sources increases the total instead. The key word is portion, not automatic elimination.
The calories of extra virgin olive oil and other edible oils are similar because they depend mainly on lipids. The differences between categories concern process, sensory profile and minor components, not a substantial calorie advantage. Choosing a more aromatic oil can help you spread a dose with satisfaction, but it does not change the laws of energy. For clinical or weight goals, amounts and the overall diet should be set with a professional, without turning a single tablespoon into the sole culprit of the result.
When assessing the quality of the diet, look at what the oil accompanies and what it replaces. The same dose on vegetables and legumes goes into a different meal from the same dose added to a dish already rich in fat. The calories stay the same, but context and satiety can change. Avoid moral labels such as good or bad for a single tablespoon. Planning works better with quantities, frequency and the overall composition of the meal.
How to spread oil across the day
Add up the oil used in cooking, in marinades, in dressings and added raw. Often only the oil poured on the plate is recorded, forgetting sautéed bases and shared preparations. Decide on an overall amount consistent with the advice you have received and distribute it where it gives the most flavour. A teaspoon emulsified with lemon or vinegar coats vegetables better; a final drizzle on a soup can be more noticeable than the same oil dispersed in a long cook.
Use dispensers, bottles with a controllable spout or small pre-weighed containers. Do not pour directly from a large tin, because the gesture is hard to repeat. In family recipes, measure the total oil and divide by portions, knowing that the distribution will not be perfect but the estimate will improve. If a meal plan specifies an exact amount, ask whether it is expressed in grams or tablespoons and which measure is meant. Clarity about the unit avoids daily differences that, added together, become significant.
To distribute the dose, pour the planned oil into a small cup at the start of the preparation and use only that amount between cooking and finishing. If some is left, you can decide where to add it; if it runs out too soon, you will understand which phase absorbs the most. The method makes the total visible without weighing every gesture. It is especially useful when several people cook or when there is a tendency to add oil at different moments, forgetting earlier doses.
Techniques for getting flavour from a controlled dose
A fragrant oil can be brought out by distributing it evenly. Emulsify it with a watery, acidic component to dress salads, brush it on vegetables and baking trays instead of pouring by eye, or use a teaspoon to finish individual portions. Adding part of the oil at the end of cooking preserves the aromas better and makes the gesture recognisable. These techniques do not magically reduce calories, but they increase the sensory yield of the chosen amount.
Match the intensity to the dish: a delicate fruity oil may be enough on light ingredients, while legumes and soups can handle more structured profiles. Taste before adding more. In baking and doughs, always weigh the oil because the volume indicated by spoons can alter consistency as well as calories. Control should not impoverish your cooking; on the contrary, it lets you use a better product where you really taste it. Precision thus becomes a gastronomic tool as well as a nutritional one.
Experiment with distribution techniques on the same portion: a teaspoon poured in the centre, an emulsion and a brush. Taste how evenly the flavour arrives. Often distribution matters more than increasing the quantity. Then choose the simplest technique for the dish. Do not use unsuitable sprays or containers that are hard to clean. Precision and hygiene must go together. A good extra virgin olive oil deserves a dosage that lets you perceive its aromas without turning every recipe into a stressful count.
Common counting mistakes
The first mistake is using the value per 100 grams as if it were that of a serving. The second is considering every tablespoon identical. The third is forgetting the oil shared in recipes and dressings; the fourth is counting all the frying oil as ingested. Label rounding can also create small differences that should not become a source of anxiety. For most people, what matters is adopting a consistent, repeatable method.
When you compare online sources, check the units and the serving size before concluding that the numbers conflict. If one source speaks of 15 ml and another of 10 g, they are describing different quantities. Use the label for the energy value and the scale for your dose. In the presence of diabetes, metabolic disorders or therapeutic goals, integrate the figure into a plan defined by a professional. The tablespoon number is useful only when it improves a concrete decision, not when it replaces the view of the whole diet.
If the numbers fuel anxiety or rigid behaviour, stop self-monitoring and talk to a professional. Tables are tools, not goals. For those following clinical prescriptions, use the units indicated by the doctor or dietitian and bring your usual utensil to the appointment. For everyone else, a week of measuring may be enough to calibrate your eye. Knowing the calories becomes useful when it supports stable choices, flavour and variety, not when it reduces a meal to an isolated sum.
In summary
Olive oil provides 899 kcal per 100 g according to CREA. A 10 g serving provides about 90 kcal. A household tablespoon can hold different amounts: to count accurately, weigh the oil instead of relying on volume by eye.

FAQ
How many calories are in 10 g of oil?
About 90 kcal according to the CREA table for olive oil.
Is a tablespoon always 10 g?
No. Size and fill level change; a scale is more precise.
Does extra virgin olive oil have fewer calories?
No, its energy content is similar to that of other oils.
Can you use oil on a low-calorie diet?
Yes, in the amounts set out in the meal plan; for personal advice consult a professional.
How many calories are in a teaspoon of oil?
A teaspoon of about 5 g provides approximately 45 kcal. The real value changes with the amount actually poured.
How many calories are in 100 grams of oil?
Oil is almost entirely fat and provides about 900 kcal per 100 g. For daily portions it is more useful to think in grams or teaspoons.
Does cooked oil have more calories than raw oil?
For the same quantity, the energy does not increase because the oil is heated. What changes is the amount absorbed by the food and the losses left in the pan.
How many millilitres are in a tablespoon of oil?
A tablespoon is often estimated at around 15 ml, but household utensils are not standardised. For precision use a scale or a measuring cup.
How do you measure oil without a scale?
Always use the same teaspoon or a dispenser and count the portions. For precise recipes or meal plans, the scale remains the most reliable choice.
Is there an oil with few calories?
Edible oils have very similar energy values. The practical difference depends mainly on the portion, not on the promise of a "light" oil.
