Convert Watt to Milliwatt
1,000
1 W = 1,000 mW
Use the conversion factor 1 W = 1000 mW. To convert Watt to Milliwatt, multiply the input value by 1000.
Conversion Formula
mW = W Γ 1000
Reverse: W = mW Γ 0.001
Conversion Examples
1 W Γ 1,000 =
1,000 mW
1 Watts = 1,000 Milliwatts
5 W Γ 1,000 =
5,000 mW
5 Watts = 5,000 Milliwatts
10 W Γ 1,000 =
10,000 mW
10 Watts = 10,000 Milliwatts
25 W Γ 1,000 =
25,000 mW
25 Watts = 25,000 Milliwatts
50 W Γ 1,000 =
50,000 mW
50 Watts = 50,000 Milliwatts
100 W Γ 1,000 =
100,000 mW
100 Watts = 100,000 Milliwatts
