How to convert watts to nano Watts (nW)
The power P in nanowatts (nW) is equal to the power P in watts (W) divided by 10 to the power minus 9:
P(nW) = P(W) / 10-9
By reversing,
1 nW = 0.000000001 W
Example: Radio and Radar receivers
How to convert watts to microwatts (µW)
The microwatt is equal to the watt divided by 10 to the power minus 6
P(µW) = P(W) ⋅ 10-6
1 µW = 0.000001 W
Example: Integrated Circuits
How to convert watts to milliwatts (mW)
The milliwatt is equal to the watt divided by 10 to the power minus 3
P(mW) = P(W) ⋅ 10-3
1 mW = 0.001 W
Example: Smart Phone
How to convert watts to kilowatts (kW)
The kilowatt is equal to the watt divided by 10 to the power 3
P(µW) = P(W) ⋅ 103
1 kW = 1000 W
Example: Motors, drier, grinder
How to convert watts to Megawatts (MW)
The kilowatt is equal to the watt divided by 10 to the power 6
P(µW) = P(W) ⋅ 106
1 MW = 1000000 W
Example: Turbo Alternator
How to convert watts to Giga-watts (GW)
The gigawatt is equal to the watt divided by 10 to the power 6
P(GW) = P(W) ⋅ 109
1 GW = 1000000000 W
Example: Transmission Lines
How to convert watts to dBW
The power P in decibel-milliwatts (dBW) is equal to 10 times base 10 logarithms of the power P in watts (W) divided by 1 watt:
P(dBW) = 10 ⋅ log10( P(W) / 1W)
Example: Fibre-optic communication cables
