How the formula works
Both nanowatt and femtowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in nanowatts by 1.000000e+06 to get femtowatts. To reverse the conversion, multiply a femtowatt value by 0.000001 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 Femtowatt (fW)?
A Femtowatt (fW) equals 1e-15 watt(s), a scaled unit of electrical power used for femto-scale electrical work.
How do I convert nanowatts to femtowatts?
Multiply the nanowatt value by 1.000000e+06 to get the equivalent in femtowatts. For example, 5 nW × 1.000000e+06 = 5.000000e+06 fW.
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 femtowatts back to nanowatts?
Yes. Divide the femtowatt value by 1.000000e+06, or multiply it by 0.000001, to get nanowatts.
