How the formula works
Both petawatt and microwatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in petawatts by 1.000000e+21 to get microwatts. To reverse the conversion, multiply a microwatt value by 1.000000e-21 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 Microwatt (uW)?
A Microwatt (uW) equals 1e-06 watt(s), a scaled unit of electrical power used for micro-scale electrical work.
How do I convert petawatts to microwatts?
Multiply the petawatt value by 1.000000e+21 to get the equivalent in microwatts. For example, 5 PW × 1.000000e+21 = 5.000000e+21 uW.
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 microwatts back to petawatts?
Yes. Divide the microwatt value by 1.000000e+21, or multiply it by 1.000000e-21, to get petawatts.
