How to Convert Milliwatts to Watts
To convert milliwatts to watts, divide the value by 1000.
The Formula
Watts = Milliwatts ÷ 1000
Key Fact
1 watt = 1000 milliwatts
Tip: To convert watts back to milliwatts, multiply by 1000.
Milliwatts to Watts
Convert milliwatts (mW) to watts (W) with formulas, examples, and conversion tables.
mW
W
1 mW = 0.001 W
Full precision:0.001 W
Step-by-Step Solution
To convert 1 milliwatts to watts, we divide by 1000 because one watt equals exactly 1000 milliwatts.
1 watt = 1000 milliwatts
Since there are 1000 milliwatts in every watt, we divide our value by this factor:
1 ÷ 1000 = 0.001 watts
So 1 milliwatts = 0.001 watts.
Quick check: 0.001 × 1000 = 1 milliwatts
Example Conversions
Example 1: 1 mW = 0.001 W
1 ÷ 1000 = 0.001
1 ÷ 1000 = 0.001
Example 2: 5 mW = 0.005 W
5 ÷ 1000 = 0.005
5 ÷ 1000 = 0.005
Example 3: 10 mW = 0.01 W
10 ÷ 1000 = 0.01
10 ÷ 1000 = 0.01
