This converter allows you to convert kilocalories per hour [kcal/h] to milliwatts [mW] or milliwatts [mW] to kilocalories per hour [kcal/h]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.

1 kilocalorie per hour [kcal/h] = 1,163 milliwatts [mW]1 milliwatt [mW] ≈ 8.598 * 10-4 kilocalories per hour [kcal/h]

Convert kilocalories per hour to milliwatts

There are two simple ways to convert kilocalories per hour [kcal/h] to milliwatts [mW]. In the first calculation method, the value in kilocalories per hour [kcal/h] is divided by the rounded conversion factor of 8.598 * 10-4. The second method multiplies the value in kilocalories per hour [kcal/h] by 1,163.

  • Milliwatts [mW] ≈ kilocalories per hour [kcal/h] ÷ (8.598 * 10-4)
  • Milliwatts [mW] = kilocalories per hour [kcal/h] * 1,163

The calculation method with a rounded conversion value is more suitable for rough conversions from kilocalories per hour [kcal/h] to milliwatts [mW], as the calculation result may contain rounding errors. Therefore, the variant with the exact conversion factor is more suitable.


Convert milliwatts to kilocalories per hour

Converting milliwatts [mW] to kilocalories per hour [kcal/h] is easy and can be done in two ways. The first method involves multiplication, in which the value in milliwatts [mW] is multiplied by the rounded conversion factor of 8.598 * 10-4. The second variant is a division. Here, the value in milliwatts [mW] is divided by 1,163.

  • Kilocalories per hour [kcal/h] ≈ milliwatts [mW] * 8.598 * 10-4
  • Kilocalories per hour [kcal/h] = milliwatts [mW] ÷ 1,163

The rounded conversion value can cause rounding errors, resulting in inaccurate calculation results. To ensure that the conversion from milliwatts [mW] to kilocalories per hour [kcal/h] produces the most accurate calculation result possible, the conversion should be performed using the exact conversion factor.
