How the formula works
Both volt and attowatt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in volts by 1.000000e+18 to get attowatts. To reverse the conversion, multiply a attowatt 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 Attowatt (aW)?
A Attowatt (aW) equals 1e-18 watt(s), a scaled unit of electrical power used for atto-scale electrical work.
How do I convert volts to attowatts?
Multiply the volt value by 1.000000e+18 to get the equivalent in attowatts. For example, 5 V × 1.000000e+18 = 5.000000e+18 aW.
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 attowatts back to volts?
Yes. Divide the attowatt value by 1.000000e+18, or multiply it by 1.000000e-18, to get volts.
