This converter allows you to convert mechanical horsepower [hp(I)] to kilojoules per second [kJ/s] or kilojoules per second [kJ/s] to mechanical horsepower [hp(I)]. 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 mechanical horsepower [hp(I)] ≈ 0.7457 kilojoules per second [kJ/s]1 kilojoule per second [kJ/s] ≈ 1.341 mechanical horsepower [hp(I)]

Convert mechanical horsepower to kilojoules per second

There are two simple ways to convert mechanical horsepower [hp(I)] to kilojoules per second [kJ/s]. In the first calculation method, the value in mechanical horsepower [hp(I)] is divided by the rounded conversion factor of 1.341. The second method multiplies the value in mechanical horsepower [hp(I)] by the rounded conversion factor of 0.7457.

Kilojoules per second [kJ/s] ≈ mechanical horsepower [hp(I)] ÷ 1.341
Kilojoules per second [kJ/s] ≈ mechanical horsepower [hp(I)] * 0.7457

However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of mechanical horsepower [hp(I)] to kilojoules per second [kJ/s] can be achieved using the following calculation method.

Kilojoules per second [kJ/s] = mechanical horsepower [hp(I)] * 0.272155422 * 2.73997801

Convert kilojoules per second to mechanical horsepower

Converting kilojoules per second [kJ/s] to mechanical horsepower [hp(I)] 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 1.341. The second variant is a division. Here, the value in kilojoules per second [kJ/s] is divided by the rounded conversion factor of 0.7457.

Mechanical horsepower [hp(I)] ≈ kilojoules per second [kJ/s] * 1.341
Mechanical horsepower [hp(I)] ≈ kilojoules per second [kJ/s] ÷ 0.7457

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 mechanical horsepower [hp(I)] can be achieved using the following calculation method.

Mechanical horsepower [hp(I)] = kilojoules per second [kJ/s] ÷ 0.272155422 ÷ 2.73997801
