This converter allows you to convert kilocalories per hour [kcal/h] to terawatts [TW] or terawatts [TW] 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 * 10-12 terawatts [TW]1 terawatt [TW] ≈ 8.598 * 1011 kilocalories per hour [kcal/h]

Convert kilocalories per hour to terawatts

There are two simple ways to convert kilocalories per hour [kcal/h] to terawatts [TW]. In the first calculation method, the value in kilocalories per hour [kcal/h] is divided by the rounded conversion factor of 8.598 * 1011. The second method multiplies the value in kilocalories per hour [kcal/h] by 1.163 * 10-12.

  • Terawatts [TW] ≈ kilocalories per hour [kcal/h] ÷ (8.598 * 1011)
  • Terawatts [TW] = kilocalories per hour [kcal/h] * 1.163 * 10-12

However, the calculation method with rounded conversion values is only suitable for rough conversions from kilocalories per hour [kcal/h] to terawatts [TW], as rounding errors may occur in the calculation results. The following formula shows another variant that can be used to calculate results as accurately as possible.

  • Terawatts [TW] = kilocalories per hour [kcal/h] ÷ 3.6 ÷ 1012 * 4.1868

Convert terawatts to kilocalories per hour

Converting terawatts [TW] 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 terawatts [TW] is multiplied by the rounded conversion factor of 8.598 * 1011. The second variant is a division. Here, the value in terawatts [TW] is divided by 1.163 * 10-12.

  • Kilocalories per hour [kcal/h] ≈ terawatts [TW] * 8.598 * 1011
  • Kilocalories per hour [kcal/h] = terawatts [TW] ÷ (1.163 * 10-12)

However, the version with rounded conversion values can produce somewhat inaccurate calculation results, which is why it is only suitable for rough conversions from terawatts [TW] to kilocalories per hour [kcal/h]. The formula below shows an alternative method that can be used to calculate results as accurately as possible.

  • Kilocalories per hour [kcal/h] = terawatts [TW] * 3.6 * 1012 ÷ 4.1868
