femtowatt to nanowatt
Convert femtowatt (fW) to nanowatt (nW). Use an editable power converter, conversion formula, and reference table.
1 fW = 0.000001 nW
Conversion formula
One femtowatt equals 0.000001 nanowatt. Multiply your value in femtowatt by this factor to get nanowatt. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 femtowatt:5 × 0.000001 = 0.000005 nW

About these measurements
Power is the rate of energy transfer.
The base reference used here is the watt. One femtowatt is 1e-15 base units; one nanowatt is 1e-9 base units.
Important distinctions
Mechanical horsepower and metric horsepower are distinct units.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
