How the formula works
Both zeptowatt and nanowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in zeptowatts by 1.000000e-12 to get nanowatts. To reverse the conversion, multiply a nanowatt value by 1.000000e+12 to get back to zeptowatts.
Frequently asked questions
What is Zeptowatt (zW)?
A Zeptowatt (zW) equals 1e-21 watt(s), a scaled unit of electrical power used for zepto-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 zeptowatts to nanowatts?
Multiply the zeptowatt value by 1.000000e-12 to get the equivalent in nanowatts. For example, 5 zW × 1.000000e-12 = 5.000000e-12 nW.
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 nanowatts back to zeptowatts?
Yes. Divide the nanowatt value by 1.000000e-12, or multiply it by 1.000000e+12, to get zeptowatts.
