Torque Calculator
Torque from a force on a lever arm at any angle, or the force or arm length you need for a set torque.

How it's calculated
τ = F × r × sin θ
Torque is the turning effect of a force: the same push does more on a longer spanner, and most when it is at right angles to the arm. Wheel nuts are often specified around 100–140 N·m; a 300 mm wrench needs about 400 N at 90° to reach 120 N·m.
