Nm to Joules Converter
Use our Nm to joules converter to convert newton-meters (N·m) to joules (J) instantly. Includes whether joules are the same as newton meters, the Nm to joules formula, a conversion chart, and clarifies the common “nm” (nanometers) vs “N·m” confusion.
Nm to Joules: How It Works
Nm to joules conversion is a direct conversion between newton-meters (N·m) and joules (J). In physics, 1 joule is defined as the work done when a force of 1 newton moves an object 1 meter in the direction of the force—so 1 J = 1 N·m.
This converter is for N·m (newton-meter), not “nm” (nanometer). They look similar in typing, but they represent completely different things: N·m is a unit used for work/energy (and also torque), while nm is a unit of length.
A common question is “are joules the same as newton meters?” Numerically, yes: the conversion is 1-to-1. But when N·m is used as torque, people usually say “N·m” (not “joules”) to avoid confusion between torque and energy.
Nm to Joules Formula
Because 1 joule equals 1 newton-meter, converting N·m to J is a 1:1 conversion.
1 J = 1 N·m (for work/energy).
Also 1:1 in the reverse direction.
Direct 1-to-1 conversion.
Same numeric value.

Nm to Joules Conversion Chart
Since the conversion is 1:1, the values are identical.

Definitions
These definitions help clarify what “Nm” and “J” mean, and why “nm” can be confusing.
- Joule (J)
- A unit of energy/work. 1 joule is the work done by 1 newton of force moving an object 1 meter in the direction of the force.
- Newton-meter (N·m or Nm)
- A compound unit equal to newtons × meters. It can represent energy/work (where 1 N·m = 1 J) and it’s also commonly used to express torque.
- Nanometer (nm)
- A unit of length equal to 10⁻⁹ meters. This is not the same as N·m.

Frequently Asked Questions
For energy/work, yes: 1 joule equals 1 newton-meter (1 J = 1 N·m). However, newton-meters are also used to describe torque, and people typically keep the unit written as N·m to avoid confusion.
When Nm means N·m (newton-meter) as a work/energy unit, it is numerically the same as joules: J = N·m. But if Nm is being used for torque, it’s still the same dimensions, just labeled differently to avoid mixing torque and energy.
Use the identity conversion: joules = newton-meters. So if you have 12 N·m, that equals 12 J.
1 N·m equals 1 joule (1 J).
This converter is specifically Nm to J (1:1). If you need inch-pounds, use an Nm to in-lbs converter (since that uses a different conversion factor).
Not directly if “nm” means nanometers (a length). You need context (what the nanometers represent). A common case is wavelength of light: energy per photon can be found with E = h·c/λ, where λ is in meters. If λ is in nanometers, then E(J) = 1.986445857×10⁻16 ÷ λ(nm). Example: 500 nm corresponds to about 3.9729×10⁻19 J per photon.
J = N·m. It’s a 1:1 conversion.
