2,200,000

Ω

2.2 MΩ = 2,200,000 Ω

Ω = MΩ × 1,000,000

Megohms to Ohms: 1 MΩ equals 1000000 Ω. To convert megohms to ohms, multiply by 1000000 (Ω = MΩ × 1,000,000). For example, 10 MΩ = 10000000 Ω.

How to Convert Megohms to Ohms

To convert from megohms to ohms, multiply the value by 1000000. The conversion is linear, meaning doubling the input doubles the output.

Conversion Formula

  • Megohms to Ohms: Ω = MΩ × 1,000,000
  • Ohms to Megohms: MΩ = Ω ÷ 1,000,000

Understanding the Units

What is a Megohm?

The ohm is the SI derived unit of electrical resistance, equal to one volt per ampere (1 Ω = 1 V/A).

Named after Georg Simon Ohm (1789–1854), German physicist who formulated Ohm's law.

Common contexts: circuit design, electronics.

FAQ

How many ohms are in one megohm?

One megohm equals 1,000,000 ohms. The mega- prefix represents 10⁶ (one million).

What does a megohm reading indicate in insulation testing?

In insulation resistance testing, readings above 1 MΩ generally indicate acceptable insulation. Lower values may suggest moisture ingress, contamination, or insulation degradation.

How do I convert 8.2 MΩ to ohms?

Multiply by 1,000,000: 8.2 MΩ × 1,000,000 = 8,200,000 Ω.

What is the relationship between kilohms and megohms?

One megohm equals 1,000 kilohms. So 1 MΩ = 1,000 kΩ = 1,000,000 Ω.

Are megohm resistors common in circuits?

Yes, megohm resistors are used in voltage dividers for high-impedance inputs, bias networks, ESD protection, and timing circuits with capacitors.

How many ohms are in 1 megohm?

1 MΩ equals 1000000 Ω.

How do you convert megohms to ohms?

Multiply the megohm value by 1000000. Formula: Ω = MΩ × 1,000,000.

How many ohms are in 5 megohms?

5 MΩ = 5000000 Ω.

How do you convert ohms back to megohms?

Use the inverse formula: MΩ = Ω ÷ 1,000,000. For example, 1 Ω = 1.00000e-6 MΩ.

What is the difference between Megohm and Ohm?
