Torque Calculator
Calculate torque in newton-meters from force, lever arm length and the angle between them using τ = F × r × sin(θ).
Formula: τ = F × r × sin(θ)
About Torque Calculator
Torque Calculator is a free online calculator that gives you an instant, accurate result as you type. Calculate torque in newton-meters from force, lever arm length and the angle between them using τ = F × r × sin(θ).
The calculation uses the standard formula τ = F × r × sin(θ) and updates live with every change to the inputs. Everything runs client-side in your browser — fast, private, and free to use as often as you like.
Torque is greatest when the force is applied perpendicular to the lever arm (θ = 90°), which is why wrenches are pushed at right angles.
Frequently Asked Questions
