How the formula works
Both microwatt and petawatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in microwatts by 1.000000e-21 to get petawatts. To reverse the conversion, multiply a petawatt value by 1.000000e+21 to get back to microwatts.
Frequently asked questions
What is Microwatt (uW)?
A Microwatt (uW) equals 1e-06 watt(s), a scaled unit of electrical power used for micro-scale electrical work.
What is Petawatt (PW)?
A Petawatt (PW) equals 1e+15 watt(s), a scaled unit of electrical power used for peta-scale electrical work.
How do I convert microwatts to petawatts?
Multiply the microwatt value by 1.000000e-21 to get the equivalent in petawatts. For example, 5 uW × 1.000000e-21 = 5.000000e-21 PW.
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 petawatts back to microwatts?
Yes. Divide the petawatt value by 1.000000e-21, or multiply it by 1.000000e+21, to get microwatts.
