How the formula works
Both megawatt and attowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in megawatts by 1.000000e+24 to get attowatts. To reverse the conversion, multiply a attowatt value by 1.000000e-24 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 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 megawatts to attowatts?
Multiply the megawatt value by 1.000000e+24 to get the equivalent in attowatts. For example, 5 MW × 1.000000e+24 = 5.000000e+24 aW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+24 is an exact, non-rounded value.
Can I convert attowatts back to megawatts?
Yes. Divide the attowatt value by 1.000000e+24, or multiply it by 1.000000e-24, to get megawatts.
