Convert horsepower (metric) hour to watt-second
Please provide values below to convert horsepower (metric) hour [hp*h] to watt-second [W*s], or Convert watt-second to horsepower (metric) hour.
1 hp*h = 2647795.5 W*s. To convert horsepower (metric) hour to watt-second, multiply the value by 2647795.5; to go the other way, divide by it (1 W*s = 3.77672671473e-07 hp*h). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 hp*h = 2647795.5 W*s
- 1 W*s = 3.77672671473e-07 hp*h
- 10 hp*h = 26477955 W*s
- 100 hp*h = 264779550 W*s
How to Convert Horsepower (Metric) Hour to Watt-Second

Horsepower (Metric) Hour
A unit of energy representing the amount of work done by one horsepower over one hour, equivalent to 745.7 joules.
History/Origin
The horsepower hour was historically used to quantify energy in mechanical and engineering contexts, especially in the era of steam and early engines, but has largely been replaced by standard energy units like joules and kilowatt-hours.
Current Use
It is rarely used in modern practice, but may still appear in legacy systems or specific industrial applications to measure energy output or consumption related to horsepower-rated equipment.
Watt-Second
A watt-second (W·s) is a unit of energy equivalent to one joule, representing the amount of energy transferred or converted when one watt of power is applied for one second.
History/Origin
The watt-second originated from the SI system of units, where the watt (W) is the SI derived unit of power, and the second (s) is the SI base unit of time. It has been used historically in physics and engineering to quantify energy, especially in contexts where energy transfer occurs over short durations.
Current Use
The watt-second is primarily used in scientific and engineering contexts to measure small amounts of energy, such as in electrical and mechanical systems. It is often replaced by the joule in modern applications but remains a recognized unit within the energy converter category.
