How the formula works
Both attovolt and volt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attovolts by 1.000000e-18 to get volts. To reverse the conversion, multiply a volt value by 1.000000e+18 to get back to attovolts.
Frequently asked questions
What is Attovolt (aV)?
An Attovolt (aV) equals 1e-18 volt(s), a scaled unit of electric potential used for atto-scale electrical work.
What is Volt (V)?
The volt (V) is the SI unit of electric potential difference, the "push" that drives current through a circuit.
How do I convert attovolts to volts?
Multiply the attovolt value by 1.000000e-18 to get the equivalent in volts. For example, 5 aV × 1.000000e-18 = 5.000000e-18 V.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1.000000e-18 is an exact, non-rounded value.
Can I convert volts back to attovolts?
Yes. Divide the volt value by 1.000000e-18, or multiply it by 1.000000e+18, to get attovolts.
