Torque Calculator
Calculate engine torque from force and lever arm length, or convert between torque units (lb-ft, Nm, kg-m).
How It Works
Enter force in Newtons and distance in meters to calculate torque in Nm. The calculator also converts automatically to lb-ft and kg·m for convenience.
Formula
Torque (Nm) = Force (N) x Distance (m)
Frequently Asked Questions
What is the difference between torque and horsepower?
Torque is a rotational force (how hard the engine pulls), while horsepower is the rate of doing work. Torque tells you how strong an engine is at a given RPM; horsepower tells you how much total work it can sustain over time.
How do I convert Nm to lb-ft?
Multiply Newton-meters by 0.7376 to get lb-ft. For example, 300 Nm = 221.3 lb-ft. This calculator handles the conversion automatically.
