The Torque Calculator calculates rotational force (torque) from applied force and lever arm distance. This Torque Calculator applies the standard physics or science equation, returning an exact result with units. Enter your known values and instantly solve for the unknown.

The formula behind this calculator: Τ = F x r x sin(θ). As a practical example: A 10N force applied 0.5m from a pivot at 90° produces 5 N·m of torque. All results are calculated instantly in your browser — no data is stored or transmitted.

Torque Calculator FAQ

What does the Torque Calculator calculate?

Calculates rotational force (torque) from applied force and lever arm distance.

How precise are the results?

As precise as your inputs — standard floating-point arithmetic. For significant-figure rules, apply them to the final result based on input precision.

Do these formulas ignore friction and air resistance?

Where noted, yes — standard physics equations are idealised. Real-world results include friction, drag, and other factors.

Does this work on mobile?

Yes — fully responsive and optimised for smartphones, tablets, and desktop browsers.
