How the formula works
Both petawatt and nanowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in petawatts by 1.000000e+24 to get nanowatts. To reverse the conversion, multiply a nanowatt value by 1.000000e-24 to get back to petawatts.
Frequently asked questions
What is Petawatt (PW)?
A Petawatt (PW) equals 1e+15 watt(s), a scaled unit of electrical power used for peta-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 petawatts to nanowatts?
Multiply the petawatt value by 1.000000e+24 to get the equivalent in nanowatts. For example, 5 PW × 1.000000e+24 = 5.000000e+24 nW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+24 is an exact, non-rounded value.
Can I convert nanowatts back to petawatts?
Yes. Divide the nanowatt value by 1.000000e+24, or multiply it by 1.000000e-24, to get petawatts.
