How the formula works
Both attowatt and petawatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attowatts by 1.000000e-33 to get petawatts. To reverse the conversion, multiply a petawatt value by 1.000000e+33 to get back to attowatts.
Frequently asked questions
What is Attowatt (aW)?
An Attowatt (aW) equals 1e-18 watt(s), a scaled unit of electrical power used for atto-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 attowatts to petawatts?
Multiply the attowatt value by 1.000000e-33 to get the equivalent in petawatts. For example, 5 aW × 1.000000e-33 = 5.000000e-33 PW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-33 is an exact, non-rounded value.
Can I convert petawatts back to attowatts?
Yes. Divide the petawatt value by 1.000000e-33, or multiply it by 1.000000e+33, to get attowatts.
