| mΩ | Milliohm |
| MΩ | Megaohm |
Milliohms to Megaohms examples
1 mΩ
1 mΩ × 1×10⁻⁹ = 1×10⁻⁹ MΩ.
10 mΩ
10 mΩ × 1×10⁻⁹ = 1×10⁻⁸ MΩ.
100 mΩ
100 mΩ × 1×10⁻⁹ = 1×10⁻⁷ MΩ.
Milliohms compared with Megaohms
One MΩ is 1,000,000,000 times as large as one mΩ, so your number gets smaller when you convert milliohms to megaohms and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.
About milliohms and megaohms
Milliohm (mΩ): Milliohm, 0.001 Ω. Megaohm (MΩ): Megaohm, 1,000,000 Ω.
How to calculate Milliohms to Megaohms step by step
- Enter the value in mΩ (the starting unit).
- Multiply by 1×10⁻⁹, because 1 mΩ = 1×10⁻⁹ MΩ.
- The product is the value in MΩ. To go back, divide by 1×10⁻⁹ or multiply by 1,000,000,000.
