Torque from 400 HP at 6000 RPM
400 horsepower at 6,000 RPM equals approximately 350 lb·ft of torque.
How to use this tool
- Enter the horsepower rating from the spec sheet or dyno.
- Enter the RPM at which that power is produced.
- The result is torque in pound-feet using the formula Torque = HP × 5,252 ÷ RPM.
A 400 HP engine spinning at 6,000 RPM produces about 350 lb·ft of torque.
Frequently asked questions
- How do I calculate torque from horsepower?
- Use Torque (lb·ft) = HP × 5,252 ÷ RPM. For example, 400 HP at 6,000 RPM produces 400 × 5,252 ÷ 6,000 = 350.1 lb·ft of torque.
- What does higher torque at lower RPM mean?
- High torque at low RPM (common in diesels and turbocharged engines) means the engine feels strong when pulling away from a stop or climbing hills.
