Frequently asked questions
What is the source unit in this conversion?
The source unit is the foot-pound per second (ft-lb/s). Foot-pound per second is an imperial rate of mechanical work, equal to one foot-pound of work performed each second.
What is the destination unit in this conversion?
The destination unit is the btu per hour (BTU/h). BTU per hour measures power as British thermal units transferred each hour, common for heating and cooling equipment.
How do I convert foot-pounds per second to btu per hour?
Multiply the foot-pound per second value by 4.626242868 to get btu per hour. For example, 1 ft-lb/s × 4.626242868 = 4.62624 BTU/h.
Is the foot-pounds per second to btu per hour conversion exact?
Yes. Both units are defined by fixed numeric relationships to the watt, so the conversion factor used here, 4.626242868, is exact.
Where is this conversion commonly used?
It is used when comparing power ratings expressed in foot-pounds per second against equipment, engines, or specifications rated in btu per hour.
Can I convert btu per hour back to foot-pounds per second?

About this conversion
This page converts foot-pounds per second (ft-lb/s) into btu per hour (BTU/h), two units used to describe power, the rate at which energy is transferred or work is done.
Foot-pound per second is an imperial rate of mechanical work, equal to one foot-pound of work performed each second.
BTU per hour measures power as British thermal units transferred each hour, common for heating and cooling equipment.
The formula is BTU/h = ft-lb/s × 4.626242868, 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.
