Frequently Asked Questions

What is the most common unit of electrical resistance?

The ohm (Ω) is the SI unit of electrical resistance and is the most commonly used unit. It’s defined as the resistance between two points of a conductor when a constant potential difference of 1 volt produces a current of 1 ampere.

When would I need to use megohm or microhm units?

Megohms (MΩ) are typically used for very high resistances like insulation resistance, while microhms (µΩ) are used for very low resistances like conductor resistance or shunt resistors. Our converter handles both extremes accurately.

What are statohm and ESU of resistance?

Statohm and ESU (electrostatic unit) of resistance are units from the CGS (centimeter-gram-second) system of units. 1 statohm ≈ 8.987551787×10¹¹ ohms. These are used primarily in theoretical physics contexts.

What is Quantized Hall resistance?

The Quantized Hall resistance is a quantum-mechanical resistance that appears in the quantum Hall effect. It’s approximately 25,812.807 ohms and is used in precision measurements and metrology.

How accurate are the conversions?

Our converter uses exact conversion factors based on standard definitions. For practical purposes, the results can be considered mathematically exact, though real-world measurements may have experimental uncertainties.
