How the formula works
Both volt and attoampere measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in volts by 1.000000e+18 to get attoamperes. To reverse the conversion, multiply a attoampere value by 1.000000e-18 to get back to volts.
Frequently asked questions
What is Volt (V)?
The volt (V) is the SI unit of electric potential difference, the "push" that drives current through a circuit.
What is Attoampere (aA)?
A Attoampere (aA) equals 1e-18 ampere(s), a scaled unit of electric current used for atto-scale electrical work.
How do I convert volts to attoamperes?
Multiply the volt value by 1.000000e+18 to get the equivalent in attoamperes. For example, 5 V × 1.000000e+18 = 5.000000e+18 aA.
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 attoamperes back to volts?
Yes. Divide the attoampere value by 1.000000e+18, or multiply it by 1.000000e-18, to get volts.
