About Converting Megaohms to Decaohms
Megaohm and Decaohm 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 decaohm is 10 ohm units.
Formula
decaohms = megaohms × 100000
This factor comes from each unit's defined relationship to the category's base unit: 1 megaohm equals 1000000 base units, and 1 decaohm equals 10 base units, so dividing one by the other gives the direct megaohm-to-decaohm factor of 100000.
Simple example
1 MOhm × 100000 = 100,000 daOhm
1 megaohm = 100,000 decaohms.
Real-world example
120 MOhm × 100000 = 12,000,000 daOhm
120 megaohms = 12,000,000 decaohms.

Frequently asked questions
How many decaohms are in 1 megaohm?
1 megaohm equals 100,000 decaohms, using the exact defined conversion factor rather than an estimate.
How do I convert megaohm to decaohm?
Multiply the megaohm value by 100000. The converter above does this instantly to whatever precision you set.
How do I convert decaohm back to megaohm?
Use the reverse factor: 1 decaohm equals 0.00001 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 decaohm?
Decaohm (daOhm) is a unit of electricity.
Is the megaohm to decaohm conversion exact?
Yes. Both megaohm and decaohm are defined by fixed standards rather than physical artifacts, so the factor of 100000 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.
