P= w/t
SI unit of work is joule and time is second. Therefore, SI unit of power is joule/second.
1 joule/second = 1 watt
If one joule of work is done in one second by any agent then its power is said to be one watt.
Kilowatt and megawatt are higher units of power.
1 kilowatt(kW)=103 watts
1 Megawatt(MW)=106 watts
Another unit of power is horse power.
1 horse power = 746 watts
