What is Torque Calculator?

Computes rotational force (moment) exerted about an axis of rotation: Torque = Force × Radius × sin(θ).

How to Use This Calculator

  1. Enter applied force in Newtons.
  2. Enter lever arm length in meters.
  3. Select force angle in degrees.
  4. Review torque in N·m and lb-ft.

The Mathematical Formula & Variables

Torque (N·m) = Force * Radius * sin(Angle); 1 N·m = 0.73756 lb-ft

Step-by-Step Worked Example

Scenario: 200 N force applied perpendicularly (90°) at the end of a 0.5 meter wrench.

  1. Torque = 200 * 0.5 * sin(90°) = 100 N·m.
  2. In pound-feet: 100 * 0.73756 = 73.76 lb-ft.

Result: 100.00 N·m (73.76 lb-ft)

Frequently Asked Questions

Why is torque maximized at 90 degrees?

Because sin(90°) = 1.0, delivering 100% of force perpendicularly into the rotational motion.
