## How to Convert Watts to Joules

A *joule* (J) is the measure of the amount of energy dissipated to move a 1 kilogram object 1 meter using 1 newton of force.

A *watt* (W) is a measure of electrical power.

It is possible to convert watts to joules if the amount of time is also known using this formula:

Energy_{(J)} = Power_{(W)} × Time_{(s)}

In the formula above, energy is measured in joules, power is measured in watts, and time is measured in seconds. To determine the joules of energy exerted substitute the watts and time in seconds in the formula and solve.

Joules are equal to the power in watts times the time in seconds.

**For example**, find joules of energy for 50 watts of power over 25 seconds.

joules = watts × seconds

joules = 50 × 25

joules = 1,250
