438 mlw = 0.438 w. To convert milliwatts to watts, divide by 1,000: 438 ÷ 1,000 = 0.438.
How to convert milliwatts to watts
w = mlw × 0.001
- 1 mlw = 0.001 w (and 1 w = 1,000 mlw).
- Multiply the amount by the factor: 438 × 0.001 = 0.438.
- Answer: 438 mlw = 0.438 w.
Shortcut: dividing by 1,000 gives the same result as multiplying by 0.001.
