How to Convert Abohms to Ohms

To convert an abohm measurement to an ohm measurement, divide the electrical resistance by the conversion ratio.

Since one ohm is equal to 1,000,000,000 abohms, you can use this simple formula to convert:

ohms = abohms ÷ 1,000,000,000

The electrical resistance in ohms is equal to the abohms divided by 1,000,000,000.

For example, here's how to convert 500,000,000 abohms to ohms using the formula above.
500,000,000 abΩ = (500,000,000 ÷ 1,000,000,000) = 0.5 Ω

Abohms and ohms are both units used to measure electrical resistance. Keep reading to learn more about each unit of measure.


The abohm is the resistance between two points of an electrical conductor transmitting a current of one abampere when the potential difference is one abvolt. One abohm is equal to one nanoohm.

The abohm is a centimeter-gram-second (CGS) electromagnetic unit of electrical resistance. Abohms can be abbreviated as abΩ; for example, 1 abohm can be written as 1 abΩ.


The ohm is the resistance between two points of an electrical conductor transmitting a current of one ampere when the potential difference is one volt.[1]

The ohm is the SI derived unit for electrical resistance in the metric system. Ohms can be abbreviated as ; for example, 1 ohm can be written as 1 Ω.

Ohm's Law states the current between two points on a conductor is proportional to the voltage and inversely proportional to the resistance. Using Ohm's Law, it's possible to express the resistance in ohms as an expression using current and voltage.

R = VV / IA

The resistance in ohms is equal to the potential difference in volts divided by the current in amperes.
