### Watts to joules calculator W to J:

Joules of the SI unit of the energy, watt is the SI unit of power. Enter the watts, time period and press the calculate button to get the Joules in the result column.

### Watts to joules conversion formula:

Joules is the Watts times of the time period.

Let us assume,

*E*_{(J)} = Energy in Joules

*P*_{(W)}* = Power in Watts*

*t*_{(s)} = Time in Seconds

Hence,

*E*_{(J)} = *P*_{(W)}* *×* t*_{(s)}

**Example:**

Simple 1500 Watts electric heater is operated for 60 seconds, calculate the energy consumed by the heater in Joules.

Using our formula,

*E*_{(J)} = 1500 * 60

Energy in Joules = 90000 Joules.
