Power Unit Converter
Convert between watts, milliwatts, microwatts and more
Basic Power Conversion
Conversion formulas:
1 W = 1,000 mW = 1,000,000 μW = 0.001 kW
1 W = 1,000 mW = 1,000,000 μW = 0.001 kW
Additional Power Units
Scientific notation:
1 GW = 109 W, 1 MW = 106 W, 1 nW = 10-9 W, 1 pW = 10-12 W
1 GW = 109 W, 1 MW = 106 W, 1 nW = 10-9 W, 1 pW = 10-12 W

One watt is equal to 1000 milliwatts:
1W = 1000mW
Watts to milliwatts conversion formula
The power in milliwatts P(mW) is equal to 1000 times the power in watts P(W):
P(mW) = 1000 ⋅ P(W)
Example
Convert 5W to milliwatts:
P(mW) = 1000 ⋅ 5W = 5000mW
