About Converting Ronnaohms to Exaohms
Ronnaohm and Exaohm both belong to the electricity family — voltage, current, resistance, power, or energy — units that show up constantly when working across the different standards used by household wiring (120V/240V depending on region), automotive electrical systems (12V/24V), and electronics design. Specifically: Ronnaohm is 1e+27 ohm units, and exaohm is 1000000000000000000 ohm units.
Formula
exaohms = ronnaohms × 1000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 ronnaohm equals 1e+27 base units, and 1 exaohm equals 1e+18 base units, so dividing one by the other gives the direct ronnaohm-to-exaohm factor of 1000000000.
Simple example
1 ROhm × 1000000000 = 1,000,000,000 EOhm
1 ronnaohm = 1,000,000,000 exaohms.
Real-world example
120 ROhm × 1000000000 = 120,000,000,000 EOhm
120 ronnaohms = 120,000,000,000 exaohms.

Reverse conversion: Exaohm to Ronnaohm
1 EOhm × 1e-9 = 1e-9 ROhm
1 exaohm = 1e-9 ronnaohms.
ronnaohms = exaohms × 1e-9

Frequently asked questions
How many exaohms are in 1 ronnaohm?
1 ronnaohm equals 1,000,000,000 exaohms, using the exact defined conversion factor rather than an estimate.
How do I convert ronnaohm to exaohm?
Multiply the ronnaohm value by 1000000000. The converter above does this instantly to whatever precision you set.
How do I convert exaohm back to ronnaohm?
Use the reverse factor: 1 exaohm equals 1e-9 ronnaohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a ronnaohm?
Ronnaohm (ROhm) is a unit of electricity.
What is a exaohm?
Exaohm (EOhm) is a unit of electricity.
Is the ronnaohm to exaohm conversion exact?
Yes. Both ronnaohm and exaohm are defined by fixed standards rather than physical artifacts, so the factor of 1000000000 used above is exact to as many digits as you choose to display.
What's the difference between voltage, current, and resistance?
Voltage (volts) is the electrical potential difference driving current through a circuit. Current (amperes) is the rate of flow of electric charge. Resistance (ohms) is how much a component opposes that flow. They're related by Ohm's law (V = I × R), but they are distinct physical quantities, and this page converts between units of just one of them.
