Understanding Joules and Watt-Seconds

What is a Joule?

A joule (J) is the SI unit of energy, defined as the energy transferred when applying a force of one newton through a distance of one meter. One joule equals exactly one watt-second, making the conversion straightforward.

What is a Watt-Second?

A watt-second (Ws) represents the energy of one watt sustained for one second. It's equivalent to one joule, making it a useful unit in electrical and mechanical engineering calculations.

Conversion Formula

The conversion between joules and watt-seconds is 1:1, meaning:

1 Joule (J) = 1 Watt-second (Ws)
