# How do you convert kcal to kJ?

## How do you convert kcal to kJ?

One calorie (kcal) equals 4.18 kJ or 4,184 joules (J) ( 1 ). To convert from calories to kJ, multiple calories by 4.18. Conversely, to convert from kJ to calories, divide kJ by 4.18. For example, a medium-sized banana (118 grams) provides 105 calories (kcal) or 439 kJ ( 2 ).

## How do you change kJ to KCAL?

How to convert from kilojoules to kcal

1. Kilojoules to international kilocalories. 1 kcalIT = 4.1868 kJ. The energy in international kilocalories E(kcal-IT) is equal to the energy in kilojoules E(kJ) divided by 4.1868:
2. Kilojoules to 15°C kilocalories. 1 kcal15 = 4.1855 kJ.
3. Kilojoules to 20°C kilocalories. 1 kcal20 = 4.182 kJ.

Is a kcal the same as a calorie?

The “calorie” we refer to in food is actually kilocalorie. One (1) kilocalorie is the same as one (1) Calorie (uppercase C). A kilocalorie is the amount of heat required to raise the temperature of one kilogram of water one degree Celsius.

How many calories are in a KCAL?

Thus, 1 kilocalorie (kcal) = 1000 calories (cal).

### Is 1 kJ a calorie?

Energy as kilojoules Food energy used to be measured in Calories (Cal) and some countries still use those units. The conversions are as follows: 1 kJ = 0.2 Cal.

### Which is bigger Cal or kcal?

This information will appear under the “Energy” heading. The calorie content is often given in kcals, which is short for kilocalories, and also in kJ, which is short for kilojoules. A kilocalorie is another word for what’s commonly called a calorie, so 1,000 calories will be written as 1,000kcals.

How many kcal should I burn a day?

A sedentary woman aged 19 to 30 burns 1,800 to 2,000 calories daily, while a sedentary woman aged 31 to 51 burns about 1,800 calories per day. An active woman between 19 and 30 burns about 2,400 calories per day, while an active woman aged 31 to 51 burns about 2,200 calories.

How do you calculate Kcal in food?

The formula is Energy (in Kcal) = 4x (Proteins and carbohydrates mass in grams) + 9 x mass of fat in grams.
