| MΩ | Megaohm |
Ohms to Megaohms examples
1 Ω
1 Ω × 0.000001 = 0.000001 MΩ.
10 Ω
10 Ω × 0.000001 = 0.00001 MΩ.
100 Ω
100 Ω × 0.000001 = 0.0001 MΩ.
Ohms compared with Megaohms
One MΩ is 1,000,000 times as large as one Ω, so your number gets smaller when you convert ohms to megaohms and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
About ohms and megaohms
Ohm (Ω): The ohm, the SI unit of electrical resistance. Megaohm (MΩ): Megaohm, 1,000,000 Ω.
How to calculate Ohms to Megaohms step by step
- Enter the value in Ω (the starting unit).
- Multiply by 0.000001, because 1 Ω = 0.000001 MΩ.
- The product is the value in MΩ. To go back, divide by 0.000001 or multiply by 1,000,000.
