Kcal to kW Formula

The following formulas convert kilocalorie rates to power and back using 1 kcal = 4184 joules.

\mathrm{kW} = 0.001162222\,\mathrm{kcal/h}
  • 1 kilocalorie (kcal) = 4184 joules (J)
  • 1 kcal/h = 1.162222 W (≈ 0.001162222 kW)
  • 1 kcal/min = 69.733333 W (≈ 0.069733 kW)
  • 1 kcal/s = 4184 W (≈ 4.184 kW)

* 1 kcal/h = 0.001162222 kW (exact ratio uses 4184 J per kcal).

How do you convert kcal/h to kW? Multiply by 0.001162222 (or divide by 860.42065): kW = (kcal/h) × 0.001162222.

How do you convert kW to kcal/h? Multiply by 860.42065: kcal/h = kW × 860.42065.

Example Problem

Convert 2,500 kcal/h to kW.

Use the formula: kW = (kcal/h) × 0.001162222.

kW = 2,500 × 0.001162222 = 2.905556 kW
