Newton Meter to Joule Converter
Convert Newton-metres to Joules and back. 1 N·m = 1 J exactly — both measure energy, though N·m is also used for torque.

Note: 1 N·m = 1 J exactly (as work/energy). For torque, N·m and J are dimensionally equal but conceptually different.
This tool provides general unit conversions for everyday and educational use. For regulated, legal, or scientific applications, verify conversion factors against the applicable official standard.
About the Newton Meter to Joule Converter
The newton meter to joule converter reflects the fact that 1 N·m = 1 J: a force of one newton acting through one metre does one joule of work. The units are the same dimensionally, but by convention newton-metres are used for torque and joules for energy and work. The tool also shows kilojoules, calories and kilowatt-hours.
How to use it
- 1Choose N·m → J or J → N·m.
- 2Enter the value.
- 3Read the result and the equivalents.
- 4Copy, share or print the result with the buttons below it.
Worked example
lifting a 10 kg mass by 2 m does 10 × 9.81 × 2 ≈ 196 N·m of work, which is 196 J.
How it works
Why 1 N·m = 1 J?
Force (N) × distance (m) = work (J). When a force of 1 Newton acts through a distance of 1 metre, 1 Joule of work is done. Dimensionally: N·m = kg·m²/s² = J.
Common use cases
- Physics homework on work and energy
- Understanding the difference between torque and energy
- Engineering calculations
Frequently asked questions
A:Dimensionally yes (both = N·m = J), but they are different concepts. Torque is a rotational force; energy is scalar. Numerically 1 N·m of torque ≠ 1 J of energy unless the moment arm rotates 1 radian.
A:1 kWh = 3,600,000 J = 3.6 MJ.
