| Six metric units the watt, kelvin, farad, newton, joule and gray are named after British scientists. |
| One joule is equivalent to the work required to produce one watt of power continuously for one second. |
| The unit used for measuring energy is the joule. But one joule only represents a tiny amount of energy. |
| A force of one newton moving through a distance of one metre does one joule of work. |
| One joule is the amount of work done by exerting a force of one newton to displace an object by one meter. |
| One joule of output energy will energise approximately 6 miles of wire with no interference. |
