This torque calculator finds the turning moment using T = F × r, where F is the applied force and r is the radius (lever arm).
Torque Calculator
Formula
T = F × r (newton-metres, N·m)
How to Use This Calculator
- Enter the applied force in newtons.
- Enter the radius or lever-arm length in metres.
- Click Calculate to get the torque in N·m.
Worked Example
A force of 50 N applied at a radius of 0.3 m gives a torque of T = 50 × 0.3 = 15 N·m.
Frequently Asked Questions
What is the formula for torque?
Torque T = force x perpendicular distance (radius): T = F x r.
What is the unit of torque?
The SI unit of torque is the newton-metre (N.m).
What is the difference between torque and force?
Force is a push or pull; torque is the rotational (turning) effect of that force about an axis.
