This converter allows you to convert joules per hour [J/h] to metric horsepower [PS] or metric horsepower [PS] to joules per hour [J/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 joule per hour [J/h] ≈ 3.777 * 10-7 metric horsepower [PS]1 metric horsepower [PS] = 2,647,795.5 joules per hour [J/h]

Convert joules per hour to metric horsepower

There are two simple ways to convert joules per hour [J/h] to metric horsepower [PS]. In the first calculation method, the value in joules per hour [J/h] is divided by 2,647,795.5. The second method multiplies the value in joules per hour [J/h] by the rounded conversion factor of 3.777 * 10-7.

  • Metric horsepower [PS] = joules per hour [J/h] ÷ 2,647,795.5
  • Metric horsepower [PS] ≈ joules per hour [J/h] * 3.777 * 10-7

The calculation method with a rounded conversion value is more suitable for rough conversions from joules per hour [J/h] to metric horsepower [PS], as the calculation result may contain rounding errors. Therefore, the variant with the exact conversion factor is more suitable.


Convert metric horsepower to joules per hour

Converting metric horsepower [PS] to joules per hour [J/h] is easy and can be done in two ways. The first method involves multiplication, whereby the value in metric horsepower [PS] is multiplied by 2,647,795.5. The second variant is a division. Here, the value in metric horsepower [PS] is divided by the rounded conversion factor of 3.777 * 10-7.

  • Joules per hour [J/h] = metric horsepower [PS] * 2,647,795.5
  • Joules per hour [J/h] ≈ metric horsepower [PS] ÷ (3.777 * 10-7)

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