Frequently Asked Questions

What is the exact difference between a calorie and a kilocalorie?

In scientific physics, a small calorie (cal) is the energy needed to heat 1 gram of water by 1°C. In dietary nutrition, a food Calorie (with a capital C) is actually a kilocalorie (1 kcal = 1,000 small calories = 4,184 Joules). Our kj to cal calculator calculates both definitions automatically.

How many kJ should I eat per day to maintain or lose weight?

The standard daily reference intake for an average adult is 8,700 kJ (equivalent to roughly 2,000 kcal to 2,079 kcal). For moderate weight loss, a daily deficit of 2,000 kJ (~480 kcal) is generally recommended by health authorities.
