How to convert kilojoules to calories

 Just like yards became metres and pounds became grams, so calories have become kilojoules. Kilojoules are the metric equivalent of calories and have replaced calories in almost all countries. Yet they’re very confusing, especially to my US visitors who have always only known calories (lucky for me, I grew up with calories then had to learn kilojoules!)

These are the units used to measure food energy – kilojoules (abbreviated to kJ) and Calories (Cals). Kilojoules are four times larger than calories eg a bowl of cereal supplies around 480 kilojoules or 117 Calories.

Conversion is 4.2 … or just 4

1 calorie equals 4.186 kilojoules (4.2 or simply 4 is close enough for a quick conversion).
For example, a slice of bread supplies 290 kilojoules or (290 divided by 4) 70 Calories.

Kilojoules are difficult to grasp if you don’t have a feel for the numbers. So here’s a handy guide to make things more ‘friendly’.

How diets compare in kilojoules and calories
kJ cals Intake or level
10000 2400 Typical level of intake of most teenagers
8700 2070 Average intake used to calculate %DI on food labels
7500 1800 Typical weight loss level for a moderately-active man
7000 1650 Typical weight loss level for a sedentary man
6000 1500 Typical weight loss level for a moderately-active woman
5000 1200 Typical weight loss level for a sedentary woman
4000 1000 Supervised fast or meal replacement intake

– too low for normal activity

Here’s how food compares in kilojoules and calories:

Various foods in kilojoules and calories
