Torque to horsepower

hp and kW from torque and RPM — the 5,252 crossover point and per-gear readouts.

Convert engine torque at a given rpm into kW, horsepower, and metric PS — the figure spec sheets quote differently per market.

P = τω. Runs in this browser.

How to use

  1. Enter torque (lb-ft or Nm).
  2. Enter engine RPM.
  3. Read hp, kW, and PS.

What it supports

hp = torque(lb-ft) × RPM ÷ 5252 (kW = Nm × RPM ÷ 9549); torque 0–1e6, RPM 0–100,000. Peak power ignores drivetrain losses — wheel horsepower is lower.
