Convert ohms to megohms and megohms to ohms instantly. Bidirectional resistance converter with formula and common values.
To convert ohms to megohms, divide by 1,000,000 (or multiply by 0.000001). Megohms represent very high resistance values used in insulation testing and specialized electronic circuits.
| Ohms (Ω) | Megohms (MΩ) |
|---|---|
| 100,000 | 0.1 |
| 470,000 | 0.47 |
| 1,000,000 | 1 |
| 2,200,000 | 2.2 |
| 3,700,000 | 3.7 |
| 10,000,000 | 10 |
| 22,000,000 | 22 |

One ohm equals 0.000001 megohms (MΩ). Divide the ohm value by 1,000,000 to get megohms.
Megohm values appear in insulation resistance testing, high-impedance input circuits, humidity sensors, and electrostatic discharge (ESD) protection components.
A megohm meter (also called an insulation resistance tester or megger) measures very high resistances, typically in the megohm to gigaohm range, used to verify cable and motor insulation integrity.
Divide by 1,000,000: 3,700,000 Ω ÷ 1,000,000 = 3.7 MΩ.
