How the formula works
Both volt and decivolt measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in volts by 10 to get decivolts. To reverse the conversion, multiply a decivolt value by 0.1 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 Decivolt (dV)?
A Decivolt (dV) equals 1/10 volt(s), a scaled unit of electric potential used for deci-scale electrical work.
How do I convert volts to decivolts?
Multiply the volt value by 10 to get the equivalent in decivolts. For example, 5 V × 10 = 50 dV.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 10 is an exact, non-rounded value.
Can I convert decivolts back to volts?
Yes. Divide the decivolt value by 10, or multiply it by 0.1, to get volts.
