About Converting Deciohms to Megaohms
Deciohm and Megaohm 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: Deciohm is 0.1 ohm units, and megaohm is 1000000 ohm units.
Formula
megaohms = deciohms × 1e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 deciohm equals 0.1 base units, and 1 megaohm equals 1000000 base units, so dividing one by the other gives the direct deciohm-to-megaohm factor of 1e-7.
Simple example
1 dOhm × 1e-7 = 1e-7 MOhm
1 deciohm = 1e-7 megaohms.
Real-world example
120 dOhm × 1e-7 = 0.000012 MOhm
120 deciohms = 0.000012 megaohms.

Reverse conversion: Megaohm to Deciohm
1e-7 MOhm × 10000000 = 1 dOhm
1e-7 megaohms = 1 deciohms.
deciohms = megaohms × 10000000

Frequently asked questions
How many megaohms are in 1 deciohm?
1 deciohm equals 1e-7 megaohms, using the exact defined conversion factor rather than an estimate.
How do I convert deciohm to megaohm?
Multiply the deciohm value by 1e-7. The converter above does this instantly to whatever precision you set.
How do I convert megaohm back to deciohm?
Use the reverse factor: 1 megaohm equals 10,000,000 deciohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a deciohm?
Deciohm (dOhm) is a unit of electricity.
What is a megaohm?
Megaohm (MOhm) is a unit of electricity.
Is the deciohm to megaohm conversion exact?
Yes. Both deciohm and megaohm are defined by fixed standards rather than physical artifacts, so the factor of 1e-7 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.
