# What Is the Unit for Work? Scientists use the joule to measure work. One joule is equal to the work done by a force of one newton to move an object one meter in the direction of the force.

## What Is the Unit for Work?

In physics, the unit of work is the joule (symbol: J). The joule is named in honor of the English physicist James Prescott Joule (18181889).

In SI units, the unit of work is the Newton meter (symbol: Nm). The Newton meter is the SI unit of torque and equals the work done by a force of one Newton acting on a body that moves one meter in the direction of the force.

In the cgs system of units, the unit of work is the erg (symbol: erg). An erg is the amount of work done by a force of one dyne acting on a body that moves one centimeter in the direction of the force.

In the footpoundsecond (FPS) system of units, the unit of work is the footpound (symbol: ftlb). A footpound is the amount of work done by a force of one pound acting on a body that moves one foot in the direction of the force.

The unit of work can also be expressed in terms of energy. In the SI system of units, the unit of energy is the joule (symbol: J). In
