How the formula works
Both volt and ohm measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in volts by 1 to get ohms. To reverse the conversion, multiply a ohm value by 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 Ohm (Ω)?
The ohm (Ω) is the SI unit of electrical resistance, describing how strongly a material opposes current flow.
How do I convert volts to ohms?
Multiply the volt value by 1 to get the equivalent in ohms. For example, 5 V × 1 = 5 Ω.
Is this conversion exact?
Yes. Both units use fixed, defined scale factors, so the factor 1 is an exact, non-rounded value.
Can I convert ohms back to volts?
Yes. Divide the ohm value by 1, or multiply it by 1, to get volts.
