How the formula works
Both attowatt and nanowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attowatts by 1.000000e-09 to get nanowatts. To reverse the conversion, multiply a nanowatt value by 1.000000e+09 to get back to attowatts.
Frequently asked questions
What is Attowatt (aW)?
An Attowatt (aW) equals 1e-18 watt(s), a scaled unit of electrical power used for atto-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 attowatts to nanowatts?
Multiply the attowatt value by 1.000000e-09 to get the equivalent in nanowatts. For example, 5 aW × 1.000000e-09 = 5.000000e-09 nW.
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 nanowatts back to attowatts?
Yes. Divide the nanowatt value by 1.000000e-09, or multiply it by 1.000000e+09, to get attowatts.
