## Formulas for converting power units

### Conversion from kW to PS

The power of 1 metric horsepower corresponds to 735.49875 watts.

$$W = PS · 735,49875$$
$$\displaystyle PS=\frac{W}{735.49875}$$

### Conversion of kW into British horsepower

The power of 1 horsepower corresponds to 745.70 watts.

$$W = hp · 745,7$$
$$\displaystyle hp=\frac{W}{745.7}$$

### Conversion of kW to calories / second

The power of 1 calories / second corresponds to 4.1868 watts.

$$W = cal/s · 4.1868$$
$$\displaystyle cal/s=\frac{W}{4.1868}$$

### Conversion from kW to BTU / second

The power of 1 BTU / second corresponds to 1055.05585262 watts.

$$W = BTU/s · 1055.05585262$$
$$\displaystyle BTU/s=\frac{W}{1055.05585262}$$
