Understanding Newton-Meters and Torque

What is a Newton-Meter?

A newton-meter (N⋅m) is the SI (International System of Units) unit of torque. It represents the rotational force of one newton applied at a perpendicular distance of one meter from the axis of rotation.

Torque vs. Work

Although torque (N⋅m) and work/energy (Joules) have the same units, they represent different physical quantities. Torque is a rotational force, while work is energy transferred by force.

Formula

τ = r × F × sin(θ)

  • τ: Torque (N⋅m)
  • r: Distance from axis (m)
  • F: Applied force (N)
  • θ: Angle between force and lever arm
