About Converting Megaohms to Deciohms
Megaohm 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: Megaohm is 1000000 ohm units, and deciohm is 0.1 ohm units.
Formula
deciohms = megaohms × 10000000
This factor comes from each unit's defined relationship to the category's base unit: 1 megaohm equals 1000000 base units, and 1 deciohm equals 0.1 base units, so dividing one by the other gives the direct megaohm-to-deciohm factor of 10000000.
Simple example
1 MOhm × 10000000 = 10,000,000 dOhm
1 megaohm = 10,000,000 deciohms.
Real-world example
120 MOhm × 10000000 = 1,200,000,000 dOhm
120 megaohms = 1,200,000,000 deciohms.

Frequently asked questions
How many deciohms are in 1 megaohm?
1 megaohm equals 10,000,000 deciohms, using the exact defined conversion factor rather than an estimate.
How do I convert megaohm to deciohm?
Multiply the megaohm value by 10000000. The converter above does this instantly to whatever precision you set.
How do I convert deciohm back to megaohm?
Use the reverse factor: 1 deciohm equals 1e-7 megaohms. You can also use the swap control in the converter above to flip the direction instantly.
What is a megaohm?
Megaohm (MOhm) is a unit of electricity.
What is a deciohm?
Deciohm (dOhm) is a unit of electricity.
Is the megaohm to deciohm conversion exact?
Yes. Both megaohm and deciohm are defined by fixed standards rather than physical artifacts, so the factor of 10000000 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.
