1 watt: how many kilowatts, megawatts?
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:
|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|
Did you know?
The watt was named in honour of the 18th century Scottish scientist, James Watt, who is known for having patented a steam engine.
