1 kilocalorie [I.T.] = 3.970976 Btu [thermochemical].
1 Btu [thermochemical] = 0.2518272 kilocalorie [I.T.].
Multiply the value in kilocalorie [I.T.] by 3.970976 to get the result in Btu [thermochemical]. Example: 5 kcal × 3.970976 = 19.85488 Btu.
Kilocalorie [I.T.] (kcal) is a unit of energy. "I.T." stands for the International Table definition.
1 kilocalorie [I.T.] = 4,186.8 joule (J)
1 kilocalorie [I.T.] = 1,000 calorie [I.T.] (cal)
1 joule = 0.0002388459 kilocalorie [I.T.]
The SI prefix kilo- stands for 1,000, so 1 kilocalorie [I.T.] = 1,000 calorie [I.T.].
