FitDexButter: how many calories?
Butter carries 717 calories per 100 grams; a typical portion (10 g) comes to 72 calories. The tables below give the same figure in cups, spoons and slices.
- Protein0.9 g
- Carbs0.1 g
- Fat81.0 g
- Fibre0.0 g
- Protein0.1 g
- Carbs0.0 g
- Fat8.1 g
- Fibre0.0 g
Where do the calories come from?
- Protein 1%
- Carbs 0%
- Fat 99%
These percentages come from calories, not from grams: a gram of protein or carbohydrate counts as 4 calories, a gram of fat as 9. Alcohol is left out of the sum, fibre is counted with the carbohydrate, and the total always lands on one hundred.
What do these numbers mean on the plate?
Butter carries 7.2 calories per gram: 100 calories come out of just 14 grams. In this band the total is set not by the portion but by how far the container is tipped.
A typical portion is 10 g. Because tables are written per 100 grams, counting the portion as 100 grams too is a common mistake; for Butter that means overstating the calories by 900%.
In calories, one portion (10 g · 72 kcal) comes to: 11 g Walnuts. Walnuts page
One portion every day adds up to 26,171 calories a year — roughly a 3.4 kg difference. This is a linear estimate and an upper bound: as weight changes, daily needs change with it. Build your own timeline
For oils the calories per gram are almost constant; the only thing that changes is how full the spoon is. And part of what goes into the pan stays in the food.
Household measure equivalents
| Measure | Gram | Calories | Protein |
|---|---|---|---|
| Teaspoon (5 ml) | 4.8 g | 34 kcal | 0.0 g |
| Dessert spoon (10 ml) | 9.5 g | 68 kcal | 0.1 g |
| Tablespoon (15 ml) | 14 g | 102 kcal | 0.1 g |
| Glass (200 ml) | 190 g | 1,362 kcal | 1.7 g |
| 1 serving | 10 g | 72 kcal | 0.1 g |
Cup and spoon equivalents come from the food's bulk density, not from volume: a cup holds 200 millilitres, not 200 grams. Packing and how finely something is chopped move these numbers by 10-20%. Convert your own measure
How much of the daily reference intake?
| Nutrient | Daily reference | 100 g | 1 portion · 10 g |
|---|---|---|---|
| Calories | 2,000 kcal | 36% | 4% |
| Fat | 70 g | 116% | 12% |
| Carbs | 260 g | 0% | 0% |
| Protein | 50 g | 2% | 0% |
| Fibre | 25 g | 0% | 0% |
The reference values are the figures EU Regulation 1169/2011 gives for an average adult — the %RI column on labels rests on the same numbers. They are not a personal target; the fibre row is not in the regulation, the 25 grams there is EFSA's adequate intake for adults. Work out your own calorie needs
Where does it sit within its group?
It is number 8 of the 10 foods in the Oils, sauces and sweeteners group by calories per 100 grams. The group averages 490 kcal; Butter is 46% above that average.
Lighter options at the same 10 grams
| Food | Calories | Difference | Protein |
|---|---|---|---|
| MustardGood swap | 7 kcal | −65 kcal | 0.4 g |
| KetchupGood swap | 10 kcal | −62 kcal | 0.1 g |
| JamGood swap | 28 kcal | −44 kcal | 0.0 g |
The “good swap” mark only appears when an option lowers the calories without also lowering protein and fibre per 100 calories. Unmarked rows save calories but give up nutrient density. Try it with your own portion
How long does it take to burn one portion (10 g)?
- Walking — brisk (5.6 km/h)18 min
- Running — 8 km/h (7:30 min/km)8 min
- Cycling — 16-19 km/h10 min
The maths assumes 70 kg and is NET rather than gross: the resting calories that would burn without any exercise are not counted, because they do not pay for this portion. The heavier you are, the shorter the times. Calculate with your own weight

Which claims could its label carry?
EU Regulation 1924/2006 ties every label claim to a numeric threshold. Butter meets none of them; the closest one is “Protein source” (1% of its calories come from protein · threshold: at least 12%).
The values here are averages; on a real label the thresholds are applied to the product's OWN analysis. The list estimates which claim could be printed and guarantees none of them. For drinks, the calorie and fat thresholds run per 100 millilitres and are lower. Interpret your own label
Apply these numbers to your own portion
- Cups to grams converterCups, spoons, slices, handfuls — all converted to grams and calories. The difference: every food is computed with its own density, because a cup is a volume, not a weight. The same 200 ml glass holds 6.6 g of popcorn and 282 g of honey.
- Food swap calculatorWhat do you gain by replacing something you eat with a lighter alternative at the same weight? 80 foods, computed at your own portion. The difference: it marks the swaps that cut calories without cutting protein and fibre.
- Calorie calculatorEnter your height, weight, age and activity level to see your daily calorie needs, basal metabolic rate and macro split in seconds. The same formula as the FitDex app.
- Calories burned calculatorWork out the calories you burn across 27 activities, scaled to your weight and duration. What sets it apart: it subtracts your resting burn, so you see the extra the exercise actually bought you.
The values are averages taken from standard composition tables; a 10-15% difference between two products with the same name is normal, and the cooking method can double that gap. This page is for information and is not medical advice.
