Convert Newton-metre to Joule
1 newton-metre = 1 joule (J). For example, 10 newton-metre = 10 joule and 100 newton-metre = 100 joule. Type any value below to convert newton-metre to joule both ways — it runs entirely in your browser.
Torque vs energy: Newton-metre (N·m) is used both as a unit of ENERGY — where 1 N·m = 1 joule exactly — and as a unit of TORQUE (a twisting force × distance). This page converts the ENERGY meaning, so the figures above are correct for work and heat. A newton-metre of torque is a different physical quantity and does NOT convert into joules, kilowatt-hours or calories.
Newton-metre to Joule conversion formula
To convert newton-metre to joule, multiply by 1:
joule = newton-metre × 1
Going the other way, 1 joule = 1 newton-metre, so
newton-metre = joule × 1.

| 50 N·m = 50 J | 50 J = 50 N·m |
| 100 N·m = 100 J | 100 J = 100 N·m |
| 250 N·m = 250 J | 250 J = 250 N·m |
| 500 N·m = 500 J | 500 J = 500 N·m |
| 1000 N·m = 1,000 J | 1000 J = 1,000 N·m |
About newton-metre and joule
Newton-metre: A newton-metre is one newton applied over one metre. As a unit of ENERGY it is identical to the joule (1 N·m = 1 J); as a unit of TORQUE it measures rotational effort — a different physical quantity that does not convert into joules, kWh or calories.
Joule: The joule is the SI unit of energy — the work done by a force of one newton acting over one metre (1 J = 1 N·m), and also one watt-second.
Frequently asked questions
- How many joule are in 1 newton-metre?
- 1 newton-metre = 1 joule (J).
- How do I convert newton-metre to joule?
- Multiply the number of newton-metre by 1. For example, 10 newton-metre = 10 × 1 = 10 joule.
- How many newton-metre are in 1 joule?
- 1 joule = 1 newton-metre.
- Which is bigger, newton-metre or joule?
- 1 joule equals 1 newton-metre, so a joule is the larger unit.
