1 watt: how many kilowatts, megawatts?

 0 442

In this day and time, with technology dominating almost every aspect of our lives, the watt [W] became an important unit not only for physicists. Watts are used in our everyday life: from bills to energy consumption labels on electronic devices.

Watts are often used interchangeably with kilowatts and megawatts. That is why converting units of power may come in handy.

The watt is a SI (metric) unit of of power, equal to 1 joule [J] per second [s]: W= J/s.

Its value can be modified with metric prefixes, which indicate a multitude or a fraction of a given unit. For example, kilo- means ‘times 1000’ and so a kilogramme = 1000 grammes. The same is true for watts: a kilowatt = 1000 watts. For other metric prefixes, take a look at the table below:

 MULTIPLES SUBMULTIPLES Value Name Value Name 101 W deciwatt 10-1 W decawatt 102 W centiwatt 10-2 W hectowatt 103 W milliwatt 10-3 W kilowatt 106 W microwatt 10-6 W megawatt 109 W nanowatt 10-9 W gigawatt 1012 W picowatt 10-12 W terawatt 1015 W femtowatt 10-15 W petawatt 1018 W attowatt 10-18 W exawatt 1021  W zeptowatt 10-21  W zettawatt 1024 W yocowatt 10-24 W yottawatt

The watt was named in honour of the 18th century Scottish scientist, James Watt, who is known for having patented a steam engine.

 Technically Scotland doesn't count because they abolished the use of counties, hence why Inverness shire is not on the list.
