Want to know how torque relates to horsepower? Torque measures the twisting force your engine produces, while horsepower tells you how quickly that force is applied. Converting torque to horsepower helps you understand your engine’s real power.
Torque to HP Calculator
Quick Reference
- lb-ft: Pound-feet (Imperial units)
- Nm: Newton-meters (Metric units)
- RPM: Revolutions per minute (required for HP calculation)
- Formula: HP = (Torque × RPM) ÷ 5252 (for lb-ft)
300 lb-ft @ 3000 RPM = 171.4 HP
HP = (Torque × RPM) ÷ 5252
HP = (300 × 3000) ÷ 5252
HP = 900000 ÷ 5252
HP = 171.4
How to Convert Torque to Horsepower
The formula is simple:
HP = (Torque × RPM) ÷ 5252
Here, torque is in pound-feet (lb-ft) and RPM is the engine speed. This formula shows how torque and engine speed combine to create horsepower.
Example Calculation
If your engine produces 300 lb-ft of torque at 4000 RPM, then:
HP = (300 × 4000) ÷ 5252 ≈ 228.6 HP
This means your engine delivers about 229 horsepower at that speed.
