How the formula works
Both kilovolt and attovolt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in kilovolts by 1.000000e+21 to get attovolts. To reverse the conversion, multiply a attovolt value by 1.000000e-21 to get back to kilovolts.
Frequently asked questions
What is Kilovolt (kV)?
A Kilovolt (kV) equals 1,000 volt(s), a scaled unit of electric potential used for kilo-scale electrical work.
What is Attovolt (aV)?
A Attovolt (aV) equals 1e-18 volt(s), a scaled unit of electric potential used for atto-scale electrical work.
How do I convert kilovolts to attovolts?
Multiply the kilovolt value by 1.000000e+21 to get the equivalent in attovolts. For example, 5 kV × 1.000000e+21 = 5.000000e+21 aV.
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 attovolts back to kilovolts?
Yes. Divide the attovolt value by 1.000000e+21, or multiply it by 1.000000e-21, to get kilovolts.
