How to Convert Watts to Milliwatts
To convert watts to milliwatts, multiply the value by 1000.
The Formula
Milliwatts = Watts × 1000
Key Fact
1 watt = 1000 milliwatts
Tip: To convert milliwatts back to watts, divide by 1000.
Watts to Milliwatts
Convert watts (W) to milliwatts (mW) with formulas, examples, and conversion tables.
W
mW
1 W = 1000 mW
Full precision:1000 mW
Step-by-Step Solution
To convert 1 watts to milliwatts, we multiply by 1000 because one watt equals exactly 1000 milliwatts.
1 watt = 1000 milliwatts
Since each watt contains 1000 milliwatts, we multiply our value by this factor:
1 × 1000 = 1000 milliwatts
So 1 watts = 1000 milliwatts.
Quick check: 1000 ÷ 1000 = 1 watts
Example Conversions
Example 1: 1 W = 1000 mW
1 × 1000 = 1000
1 × 1000 = 1000
Example 2: 5 W = 5000 mW
5 × 1000 = 5000
5 × 1000 = 5000
Example 3: 10 W = 10000 mW
10 × 1000 = 10000
10 × 1000 = 10000
