How the formula works
Both exawatt and attowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in exawatts by 1.000000e+36 to get attowatts. To reverse the conversion, multiply a attowatt value by 1.000000e-36 to get back to exawatts.
Frequently asked questions
What is Exawatt (EW)?
An Exawatt (EW) equals 1e+18 watt(s), a scaled unit of electrical power used for exa-scale electrical work.
What is Attowatt (aW)?
An Attowatt (aW) equals 1e-18 watt(s), a scaled unit of electrical power used for atto-scale electrical work.
How do I convert exawatts to attowatts?
Multiply the exawatt value by 1.000000e+36 to get the equivalent in attowatts. For example, 5 EW × 1.000000e+36 = 5.000000e+36 aW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+36 is an exact, non-rounded value.
Can I convert attowatts back to exawatts?
Yes. Divide the attowatt value by 1.000000e+36, or multiply it by 1.000000e-36, to get exawatts.
