Convert joules (J), calories (cal), kilowatt-hours (kWh), BTU, and other energy units. Energy is the capacity to do work; the joule (J) is the SI unit (1 J = 1 N·m). Nutritional calories and electrical kWh use different reference definitions tied to joules.
This energy converter transforms values from Calories (cal) to Kilocalories (kcal). Results update instantly using the exact conversion factor.
The calorie (cal) is a unit of energy; 1 cal ≈ 4.184 J (thermochemical calorie).
The Kilocalories (kcal) is a unit of energy in the Energy category.
1 cal ÷ 1000 = 0.001 kcal
kcal = cal ÷ 1000
To convert cal to kcal, divide the value in cal by 1000 (since 1 cal = 0.001 kcal). Equivalently, multiply by 0.001. Example: 1 cal = 1 cal × 0.001 = 0.001 kcal.
10 cal = 0.01 kcal ÷ 1000 = 10 cal
