About this conversion
This page converts btu per hour (BTU/h) into horsepower (hp), two units used to describe power, the rate at which energy is transferred or work is done.
BTU per hour measures power as British thermal units transferred each hour, common for heating and cooling equipment.
Mechanical (imperial) horsepower is a traditional unit of power used for engines and motors, defined as exactly 745.6998715822702 watts.
The formula is hp = BTU/h × 0.0003930147789, derived from each unit's fixed relationship to the watt, the SI unit of power.
Because both units are defined by exact numeric relationships to the watt, this conversion is exact rather than approximate.
