How the formula works
Both milliwatt and nanowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in milliwatts by 1.000000e+06 to get nanowatts. To reverse the conversion, multiply a nanowatt value by 0.000001 to get back to milliwatts.
Frequently asked questions
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.
What is Nanowatt (nW)?
A Nanowatt (nW) equals 1e-09 watt(s), a scaled unit of electrical power used for nano-scale electrical work.
How do I convert milliwatts to nanowatts?
Multiply the milliwatt value by 1.000000e+06 to get the equivalent in nanowatts. For example, 5 mW × 1.000000e+06 = 5.000000e+06 nW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+06 is an exact, non-rounded value.
Can I convert nanowatts back to milliwatts?
Yes. Divide the nanowatt value by 1.000000e+06, or multiply it by 0.000001, to get milliwatts.
