How the formula works
Both exawatt and yoctowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in exawatts by 1.000000e+42 to get yoctowatts. To reverse the conversion, multiply a yoctowatt value by 1.000000e-42 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 Yoctowatt (yW)?
A Yoctowatt (yW) equals 1e-24 watt(s), a scaled unit of electrical power used for yocto-scale electrical work.
How do I convert exawatts to yoctowatts?
Multiply the exawatt value by 1.000000e+42 to get the equivalent in yoctowatts. For example, 5 EW × 1.000000e+42 = 5.000000e+42 yW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+42 is an exact, non-rounded value.
Can I convert yoctowatts back to exawatts?
Yes. Divide the yoctowatt value by 1.000000e+42, or multiply it by 1.000000e-42, to get exawatts.
