## Power conversion - hp,kw,ps...

The following utility will enable you to convert power expressed in one unit to another unit

Power is generally expressed in watts (W). The information in the table below provides a method of converting power from other units to watts.

Convert from these to watts (W) | multiply by |

erg's per second (erg/s) | 0.000 000 1 |

horsepower (electric) | 746 |

horsepower (hp)(metric,DIN,PS) | 735.4988 |

horsepower (hp)(U.K.) | 745.7 |

kilowatt (kW) | 1000 |

Examples:

## How do I convert PS to horsepower?

A manufacturer quotes the power of a vehicle at 250PS (Pferdestärke - German for horsepower, equal to metric horsepower and sometimes referred to as 'continental horsepower') converted to watts this would be 183874.7 (250 x 735.4988) and converted to horsepower (imperial) it would be 246.58 (183874.7 / 745.7).

To avoid all that hassle you could go straight from 250PS to 246.58hp just by dividing 250 by 1.01387 or by using the calculator above

## Which is bigger, Horsepower DIN or Horsepower PS?

They are exactly the same, also known as metric horsepower.

## Why are cars rated as 280hp in Japan but 276hp in the U.K.?

They use Metric horsepower(DIN/PS) as above, converted to imperial/UK/mechanical horsepower it's 276.17 which gets rounded to 276hp.
