How the formula works
Both megawatt and petawatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in megawatts by 1.000000e-09 to get petawatts. To reverse the conversion, multiply a petawatt value by 1.000000e+09 to get back to megawatts.
Frequently asked questions
What is Megawatt (MW)?
A Megawatt (MW) equals 1e+6 watt(s), a scaled unit of electrical power used for mega-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 megawatts to petawatts?
Multiply the megawatt value by 1.000000e-09 to get the equivalent in petawatts. For example, 5 MW × 1.000000e-09 = 5.000000e-09 PW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-09 is an exact, non-rounded value.
Can I convert petawatts back to megawatts?
Yes. Divide the petawatt value by 1.000000e-09, or multiply it by 1.000000e+09, to get megawatts.
