How the formula works
Both attowatt and yoctowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attowatts by 1.000000e+06 to get yoctowatts. To reverse the conversion, multiply a yoctowatt value by 0.000001 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 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 attowatts to yoctowatts?
Multiply the attowatt value by 1.000000e+06 to get the equivalent in yoctowatts. For example, 5 aW × 1.000000e+06 = 5.000000e+06 yW.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+06 is an exact, non-rounded value.
Can I convert yoctowatts back to attowatts?
Yes. Divide the yoctowatt value by 1.000000e+06, or multiply it by 0.000001, to get attowatts.
