How the formula works
Both attowatt and gigawatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attowatts by 1.000000e-27 to get gigawatts. To reverse the conversion, multiply a gigawatt value by 1.000000e+27 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 Gigawatt (GW)?
A Gigawatt (GW) equals 1e+9 watt(s), a scaled unit of electrical power used for giga-scale electrical work.
How do I convert attowatts to gigawatts?
Multiply the attowatt value by 1.000000e-27 to get the equivalent in gigawatts. For example, 5 aW × 1.000000e-27 = 5.000000e-27 GW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-27 is an exact, non-rounded value.
Can I convert gigawatts back to attowatts?
Yes. Divide the gigawatt value by 1.000000e-27, or multiply it by 1.000000e+27, to get attowatts.
