How the formula works
Both millivolt and yoctovolt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in millivolts by 1.000000e+21 to get yoctovolts. To reverse the conversion, multiply a yoctovolt value by 1.000000e-21 to get back to millivolts.
Frequently asked questions
What is Millivolt (mV)?
A Millivolt (mV) equals 1/1,000 volt(s), a scaled unit of electric potential used for milli-scale electrical work.
What is Yoctovolt (yV)?
A Yoctovolt (yV) equals 1e-24 volt(s), a scaled unit of electric potential used for yocto-scale electrical work.
How do I convert millivolts to yoctovolts?
Multiply the millivolt value by 1.000000e+21 to get the equivalent in yoctovolts. For example, 5 mV × 1.000000e+21 = 5.000000e+21 yV.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e+21 is an exact, non-rounded value.
Can I convert yoctovolts back to millivolts?
Yes. Divide the yoctovolt value by 1.000000e+21, or multiply it by 1.000000e-21, to get millivolts.
