This converter allows you to convert kilocalories per hour [kcal/h] to kilojoules per second [kJ/s] or kilojoules per second [kJ/s] 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.
Convert kilocalories per hour to kilojoules per second
There are two simple ways to convert kilocalories per hour [kcal/h] to kilojoules per second [kJ/s]. In the first calculation method, the value in kilocalories per hour [kcal/h] is divided by the rounded conversion factor of 859.8452. The second method multiplies the value in kilocalories per hour [kcal/h] by the rounded conversion factor of 0.0012.
- Kilojoules per second [kJ/s] ≈ kilocalories per hour [kcal/h] ÷ 859.8452
- Kilojoules per second [kJ/s] ≈ kilocalories per hour [kcal/h] * 0.0012
However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of kilocalories per hour [kcal/h] to kilojoules per second [kJ/s] can be achieved using the following calculation method.
- Kilojoules per second [kJ/s] = kilocalories per hour [kcal/h] ÷ 3,600 * 4.1868
Convert kilojoules per second to kilocalories per hour
Converting kilojoules per second [kJ/s] 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 kilojoules per second [kJ/s] is multiplied by the rounded conversion factor of 859.8452. The second variant is a division. Here, the value in kilojoules per second [kJ/s] is divided by the rounded conversion factor of 0.0012.
- Kilocalories per hour [kcal/h] ≈ kilojoules per second [kJ/s] * 859.8452
- Kilocalories per hour [kcal/h] ≈ kilojoules per second [kJ/s] ÷ 0.0012
However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of kilojoules per second [kJ/s] to kilocalories per hour [kcal/h] can be achieved using the following calculation method.
- Kilocalories per hour [kcal/h] = kilojoules per second [kJ/s] * 3,600 ÷ 4.1868

Speed
While mph is used in the USA, km/h is the standard in Europe, and seafaring and aviation rely on knots. This speed converter is the perfect tool for accurately converting between various units of speed.
