Power

hp to MMBTU/hr conversion

Convert mechanical horsepower (hp) to million BTU per hour (MMBTU/hr). Power is energy per unit time — the rating of pumps, compressors, motors, and heat duties.

1 hp = 0.002544434 MMBTU/hr

Formula

To convert mechanical horsepower to million BTU per hour, multiply the hp value by 0.002544434. To go the other way, divide by 0.002544434 (or multiply by 393.0148).
