Convert electrical units by family and calculate voltage, current, resistance, power, and energy with context values.
Context values
Some unit families need one extra value for a physically accurate result.
Deciohm is 0.1 ohm units.
Result = input x 1e-9 / 0.1.

About Converting Nanoohms to Deciohms
Nanoohm and Deciohm 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: Nanoohm is 1e-9 ohm units, and deciohm is 0.1 ohm units.
Formula
deciohms = nanoohms × 1e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 nanoohm equals 1e-9 base units, and 1 deciohm equals 0.1 base units, so dividing one by the other gives the direct nanoohm-to-deciohm factor of 1e-8.
Simple example
1 nOhm × 1e-8 = 1e-8 dOhm
1 nanoohm = 1e-8 deciohms.
Real-world example
120 nOhm × 1e-8 = 0.0000012 dOhm
120 nanoohms = 0.0000012 deciohms.

Reverse conversion: Deciohm to Nanoohm
1e-8 dOhm × 100000000 = 1 nOhm
1e-8 deciohms = 1 nanoohm.
nanoohms = deciohms × 100000000

Frequently asked questions
How many deciohms are in 1 nanoohm?
1 nanoohm equals 1e-8 deciohms, using the exact defined conversion factor rather than an estimate.
How do I convert nanoohm to deciohm?
Multiply the nanoohm value by 1e-8. The converter above does this instantly to whatever precision you set.
How do I convert deciohm back to nanoohm?
Use the reverse factor: 1 deciohm equals 100,000,000 nanoohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a nanoohm?
Nanoohm (nOhm) is a unit of electricity.
What is a deciohm?
Deciohm (dOhm) is a unit of electricity.
Is the nanoohm to deciohm conversion exact?
Yes. Both nanoohm and deciohm are defined by fixed standards rather than physical artifacts, so the factor of 1e-8 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.
