Joule (J) is the unit of energy which is used by International Standard of Units (SI). It is defined as the amount of work done by a force of one Newton acting on an object that moves over a distance of one meter. It is additionally the energy dissipated as heat when an electrical current of 1 ampere passes through a resistance of 1 ohm for one second.

It is defined as a derived unit of 1 joule per second, and is used to quantify the rate of energy transfer. Watts is a combination of amps and volts. Watts is a measurement of the amount of energy being released. The higher the wattage, the more is the power and output from the appliance.

It is a simple online calculator which converts joules to watts. You have to follow certain steps to carry out calculation.

1) Enter the energy in Joules.

2) Enter Time in Seconds.

3) Click on the calculate tab for the result.

4) For further calculation, click on reset.

**Mathematical Representation:**

The power (P) in watts (W) is the energy (E) in joules (J), divided by the time t in seconds (s):

P(W) = E(J) / t(s)

So,

watt = joule / second

or

W = J / s
