How the formula works
Both nanowatt and milliwatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in nanowatts by 0.000001 to get milliwatts. To reverse the conversion, multiply a milliwatt value by 1.000000e+06 to get back to nanowatts.
Frequently asked questions
What is Nanowatt (nW)?
A Nanowatt (nW) equals 1e-09 watt(s), a scaled unit of electrical power used for nano-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 nanowatts to milliwatts?
Multiply the nanowatt value by 0.000001 to get the equivalent in milliwatts. For example, 5 nW × 0.000001 = 0.000005 mW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 0.000001 is an exact, non-rounded value.
Can I convert milliwatts back to nanowatts?
Yes. Divide the milliwatt value by 0.000001, or multiply it by 1.000000e+06, to get nanowatts.
