Convert watt to joule/second

What is a watt?

Watt is a metric for power evaluation. It got its name after the eponymous physicist, who devoted his time and effort to this area of science. Before the introduction of this option in the late XIX century, for this purpose, horsepower was utilized. Interestingly, it was designed by the same scientist. Still, later the standard system switched to watts.

Modern watt (W) has a meaning of power at which the 1-Joule work is performed during one second. The common abbreviation is W. Many derivatives with common prefixes like kilo- and giga- are utilized in practice.

The evaluation of power in these terms serves as a key characteristic of devices that run on thermal or electrical energy. You can easily find watts on the packaging of the device, which gives the general understanding of its capacity. Thus, everything that is related to thermal or electrical power can be described using this metric.

What is a joule second?

One of the basic characteristics of different devices from the point of view of physics is power. It means the speed of doing some work or the amount of energy required for this purpose during some time.

The standard metric for its evaluation is watt, which has a meaning of 1 joule for 1 second. Therefore, 1 W = 1 (J/sec).

While it is often convenient to utilize this option, joule per second is also a good choice. The first component is a standard option for the evaluation of work. One such metric describes it for a 1-newton force applied to a meter. The latter is also a standard option.

If utilizing joule second, we can recalculate that an electric light bulb of 100 W for its lighting work consumes 100 J of energy every second. In 1 hour, it is 0.1 kWh or 360,000 Joule-second.
