About Torque Calculator
Calculate rotational torque in Newton-meters (N·m) and foot-pounds (ft-lb).. Designed for accurate, instantaneous calculations with zero wait time.
Formula
Torque (τ) = Force (F) × Lever Arm Radius (r) × sin(θ)
Example Calculation
Applying 100 N of force to a 0.5m wrench at 90° generates 50 N·m of torque.
