Convert calorie (thermochemical)s to kilocalories
1 cal = 0.001 kcal — exactly. Both units are defined against the SI, so this factor is a fraction, not an approximation.
0.001kcal
As a fraction: 1/1000
1 cal = 0.001 kcal
How to convert calorie (thermochemical)s to kilocalories
Multiply the number of calorie (thermochemical)s by 0.001 to get kilocalories.
The exact factor is 0.001 — as a fraction, 1/1000.
Calorie (thermochemical): Exactly 4.184 J. The "small" calorie.
Kilocalorie: The Calorie on food labels — 1000 small calories.
