How the formula works
Both zeptovolt and attovolt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in zeptovolts by 0.001 to get attovolts. To reverse the conversion, multiply a attovolt value by 1000 to get back to zeptovolts.
Frequently asked questions
What is Zeptovolt (zV)?
A Zeptovolt (zV) equals 1e-21 volt(s), a scaled unit of electric potential used for zepto-scale electrical work.
What is Attovolt (aV)?
An Attovolt (aV) equals 1e-18 volt(s), a scaled unit of electric potential used for atto-scale electrical work.
How do I convert zeptovolts to attovolts?
Multiply the zeptovolt value by 0.001 to get the equivalent in attovolts. For example, 5 zV × 0.001 = 0.005 aV.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 0.001 is an exact, non-rounded value.
Can I convert attovolts back to zeptovolts?
Yes. Divide the attovolt value by 0.001, or multiply it by 1000, to get zeptovolts.
