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