## Joule

Here you can convert energy units **Joule** value into **any other energy units**.

A joule is a unit of energy in the International System of Units (SI) and named after the British physicist James Prescott Joule.

The symbol for joule is J.

A joule is equal to the work done when a current of 1 ampere is passed through a resistance of 1 ohm for 1 second.

**Q = I ^{2}× R × t**

- Q = the amount of heat – the Joules (J)
- I = current intensity
- R = electrical resistance (Ω)
- t = time in which the current flows expressed in seconds

### Joule And Force

A joule definiton says that it is an energy trasferred to an object when we work with a force of 1 Newton on that object in the direction of its motion for 1m of distance.

This would give us a formula:

**W = F x d**

- W – Energy (J)
- F = force (N)
- d = distance (m)
