James Watt

The Watt is the measurement of power, and gets its name from James Watt. This is the modern metric way of measuring power.

The old way of doing it was to measure the power of something relative to the power of a horse: horsepower.

If a force of 1 Newton moves an object through a distance of 1 metre in 1 second, then 1 Watt of power is said to have been expended.
