How the formula works
Both femtowatt and nanowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in femtowatts by 0.000001 to get nanowatts. To reverse the conversion, multiply a nanowatt value by 1.000000e+06 to get back to femtowatts.
Frequently asked questions
What is Femtowatt (fW)?
A Femtowatt (fW) equals 1e-15 watt(s), a scaled unit of electrical power used for femto-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 femtowatts to nanowatts?
Multiply the femtowatt value by 0.000001 to get the equivalent in nanowatts. For example, 5 fW × 0.000001 = 0.000005 nW.
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 nanowatts back to femtowatts?
Yes. Divide the nanowatt value by 0.000001, or multiply it by 1.000000e+06, to get femtowatts.
