How the formula works
Both yoctowatt and watt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in yoctowatts by 1.000000e-24 to get watts. To reverse the conversion, multiply a watt value by 1.000000e+24 to get back to yoctowatts.
Frequently asked questions
What is Yoctowatt (yW)?
A Yoctowatt (yW) equals 1e-24 watt(s), a scaled unit of electrical power used for yocto-scale electrical work.
What is Watt (W)?
The watt (W) is the SI unit of power, equal to one joule of energy transferred per second.
How do I convert yoctowatts to watts?
Multiply the yoctowatt value by 1.000000e-24 to get the equivalent in watts. For example, 5 yW × 1.000000e-24 = 5.000000e-24 W.
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 watts back to yoctowatts?
Yes. Divide the watt value by 1.000000e-24, or multiply it by 1.000000e+24, to get yoctowatts.
