How the formula works
Both nanowatt and watt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in nanowatts by 1.000000e-09 to get watts. To reverse the conversion, multiply a watt value by 1.000000e+09 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 Watt (W)?
The watt (W) is the SI unit of power, equal to one joule of energy transferred per second.
How do I convert nanowatts to watts?
Multiply the nanowatt value by 1.000000e-09 to get the equivalent in watts. For example, 5 nW × 1.000000e-09 = 5.000000e-09 W.
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 watts back to nanowatts?
Yes. Divide the watt value by 1.000000e-09, or multiply it by 1.000000e+09, to get nanowatts.
