How the formula works
Both quectowatt and nanowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in quectowatts by 1.000000e-21 to get nanowatts. To reverse the conversion, multiply a nanowatt value by 1.000000e+21 to get back to quectowatts.
Frequently asked questions
What is Quectowatt (qW)?
A Quectowatt (qW) equals 1e-30 watt(s), a scaled unit of electrical power used for quecto-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 quectowatts to nanowatts?
Multiply the quectowatt value by 1.000000e-21 to get the equivalent in nanowatts. For example, 5 qW × 1.000000e-21 = 5.000000e-21 nW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-21 is an exact, non-rounded value.
Can I convert nanowatts back to quectowatts?
Yes. Divide the nanowatt value by 1.000000e-21, or multiply it by 1.000000e+21, to get quectowatts.
