Introduction

Torque Calculator — τ = r × F × sin(θ) for rotational systems. Enter Force (N), Radius (m), Angle (°) to get an instant, accurate result.

Formule

Torque = force × radius × sin(angle).

Étape par étape

1. Enter the Force (N).
2. Enter the Radius (m).
3. Enter the Angle (°).
4. Click Calculate to see your result instantly.

Exemple concret

Example: With Force (N) = 50, Radius (m) = 0.3, Angle (°) = 90, the Torque Calculator gives Torque Nm: 15.

Questions Fréquentes

Why does angle matter?

Only the component of force perpendicular to the lever arm produces torque — at 90° the full force contributes, at 0° none does.

What is torque used for?

Measuring rotational force, such as tightening a bolt or an engine's twisting output.

What inputs does the Torque Calculator need?

You'll need to provide: Force (N), Radius (m), Angle (°). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.

How accurate is the Torque Calculator?

The Torque Calculator applies the formula exactly as calculated — Torque = force × radius × sin(angle). — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.

Is the Torque Calculator free to use?

Yes, the Torque Calculator is completely free, requires no signup, and runs instantly in your browser.

À propos de Calculateur de couple

The Torque Calculator uses a real, verifiable formula — Torque = force × radius × sin(angle). — so results are accurate every time, not an approximation.
