How the formula works
Both picowatt and milliwatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in picowatts by 1.000000e-09 to get milliwatts. To reverse the conversion, multiply a milliwatt value by 1.000000e+09 to get back to picowatts.
Frequently asked questions
What is Picowatt (pW)?
A Picowatt (pW) equals 1e-12 watt(s), a scaled unit of electrical power used for pico-scale electrical work.
What is Milliwatt (mW)?
A Milliwatt (mW) equals 1/1,000 watt(s), a scaled unit of electrical power used for milli-scale electrical work.
How do I convert picowatts to milliwatts?
Multiply the picowatt value by 1.000000e-09 to get the equivalent in milliwatts. For example, 5 pW × 1.000000e-09 = 5.000000e-09 mW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-09 is an exact, non-rounded value.
Can I convert milliwatts back to picowatts?
Yes. Divide the milliwatt value by 1.000000e-09, or multiply it by 1.000000e+09, to get picowatts.
