Convert therm to horsepower (metric) hour
Please provide values below to convert therm [thm] to horsepower (metric) hour [hp*h], or Convert horsepower (metric) hour to therm.
1 thm = 39.8465818074 hp*h. To convert therm to horsepower (metric) hour, multiply the value by 39.8465818074; to go the other way, divide by it (1 hp*h = 0.0250962555542 thm). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 thm = 39.8465818074 hp*h
- 1 hp*h = 0.0250962555542 thm
- 10 thm = 398.465818074 hp*h
- 100 thm = 3984.65818074 hp*h
How to Convert Therm to Horsepower (Metric) Hour
1 thm = 39.8465818073941 hp*h
Example: convert 15 thm to hp*h:
15 thm = 15 × 39.8465818073941 hp*h = 597.698727110912 hp*h

Therm
A therm is a unit of energy used primarily to measure natural gas consumption, equivalent to 100,000 British thermal units (BTUs).
History/Origin
The therm was introduced in the early 20th century by the American Gas Association to standardize natural gas billing and measurement; it became widely adopted in North America for energy calculations.
Current Use
Today, the therm is still used in the natural gas industry for billing and energy measurement, although other units like gigajoules and cubic meters are also common globally.
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energy in mechanical and engineering contexts, especially in the era of steam and early engines, but has largely been replaced by standard energy units like joules and kilowatt-hours.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.
