One Calorie (with an uppercase C) is also known as a ‘kilocalorie’ (1000 calories with a lower case c). This calculator coverts between Calories and kilojoules, where 1 Calorie equals 4.184 kilojoules, rounded to the nearest whole number.

### Why do we use calories instead of kilocalorie?

A kilocalorie equals 1,000 “small” calories, which is the energy it takes to raise the temperature in 1 gram of water 1 degree Celsius. On U.S. food labels, the term “calorie” actually means kilocalorie, though a calorie is technically the smaller measurement.

### How many kilocalories should I burn in a day?

How to calculate kilojoules?

how active you are in your daily activities

• the amount and type of exercise you do
• your sex – men generally have higher energy requirements than women,because they have more muscle tissue
• your body composition – muscle tissue has a big appetite for kilojoules.
• if you are pregnant or breastfeeding
• genetics and your health status
• ## How do you convert joules to calories?

So, to convert from joules to calories, all you have to do is multiply by 0.239. For example, multiply 5,000 J by 0.239 to get 1,195 cal. Therefore, 5 kJ = 1,195 calories. Convert the calories (cal) into kilocalories (kcal) if desired. Simply divide the number of calories by 1,000 to get the number of kilocalories.

## How many joules are in one calorie?

One calorie is equal to 4.184 joules, a common unit of energy used in the physical sciences. Most of us think of calories in relation to things we eat and drink, as in “This can of soda has 200 calories.” It turns out that the calories listed on a food package are actually kilocalories (1000 calories = 1 kilocalorie).
