470 mΩ = 0.47 Ω

Ω = mΩ ÷ 1000

Milliohms to Ohms: 1 mΩ equals 0.001 Ω. To convert milliohms to ohms, multiply by 0.001 (Ω = mΩ ÷ 1000). For example, 10 mΩ = 0.01 Ω.

How to Convert Milliohms to Ohms

To convert from milliohms to ohms, multiply the value by 0.001. The conversion is linear, meaning doubling the input doubles the output.

Conversion Formula

  • Milliohms to Ohms: Ω = mΩ ÷ 1000
  • Ohms to Milliohms: mΩ = Ω × 1000

Understanding the Units

What is a Milliohm?

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 do I convert milliohms to ohms?

Divide the value in milliohms by 1,000. For example, 470 mΩ ÷ 1,000 = 0.47 Ω.

What is a milliohm?

A milliohm (mΩ) is one-thousandth of an ohm (0.001 Ω). It is used to express very low resistance values.

What components have milliohm resistance?

Current sense resistors, wire bonds, PCB traces, switch contacts, and battery internal resistance are typically in the milliohm range.

Why is milliohm measurement difficult?

Lead resistance and contact resistance can be comparable to the measurement itself. Four-wire Kelvin sensing eliminates these errors.

How many ohms are in 1 milliohm?

1 mΩ equals 0.001 Ω.

How do you convert milliohms to ohms?

Multiply the milliohm value by 0.001. Formula: Ω = mΩ ÷ 1000.

How many ohms are in 5 milliohms?

5 mΩ = 0.005 Ω.

How do you convert ohms back to milliohms?

Use the inverse formula: mΩ = Ω × 1000. For example, 1 Ω = 1000 mΩ.

What is the difference between Milliohm and Ohm?

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