How the formula works
Both nanowatt and zeptowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in nanowatts by 1.000000e+12 to get zeptowatts. To reverse the conversion, multiply a zeptowatt value by 1.000000e-12 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 Zeptowatt (zW)?
A Zeptowatt (zW) equals 1e-21 watt(s), a scaled unit of electrical power used for zepto-scale electrical work.
How do I convert nanowatts to zeptowatts?
Multiply the nanowatt value by 1.000000e+12 to get the equivalent in zeptowatts. For example, 5 nW × 1.000000e+12 = 5.000000e+12 zW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+12 is an exact, non-rounded value.
Can I convert zeptowatts back to nanowatts?
Yes. Divide the zeptowatt value by 1.000000e+12, or multiply it by 1.000000e-12, to get nanowatts.
