milliwatt to picowatt
Convert milliwatt (mW) to picowatt (pW). Use an editable power converter, conversion formula, and reference table.
1 mW = 1,000,000,000 pW
Conversion formula
One milliwatt equals 1,000,000,000 picowatt. Multiply your value in milliwatt by this factor to get picowatt. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 milliwatt:5 × 1,000,000,000 = 5,000,000,000 pW

About these measurements
Power is the rate of energy transfer.
The base reference used here is the watt. One milliwatt is 0.001 base units; one picowatt is 1e-12 base units.
Important distinctions
Mechanical horsepower and metric horsepower are distinct units.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert mW to pW?
Multiply the quantity in mW by 1,000,000,000. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the picowatt to milliwatt converter.
