Ohm Meter

Ω·m

Definition

The SI base unit of electric resistivity, representing the resistance of a material per unit length when a current flows through it. One ohm meter is the resistivity of a material that has a resistance of one ohm when the current flows through a cube of the material with sides of one meter.

History/Origin

Named after Georg Simon Ohm, the German physicist who formulated Ohm's law in 1827. The ohm meter unit was established as part of the International System of Units (SI) to provide a standardized measure of electrical resistivity.

Current Use

Widely used in electrical engineering, materials science, and physics for measuring the electrical resistance properties of conductors, semiconductors, and insulators. Essential for designing electrical circuits, cables, and electronic components.

Ohm Inch

Ω·in

Definition

An imperial unit of electric resistivity equal to 0.0254 ohm meters. Used primarily in countries following imperial measurement systems for electrical resistivity measurements and material characterization.

History/Origin

Developed as an imperial equivalent to the metric ohm centimeter for electrical resistivity measurements. The inch-based unit was commonly used in North American electrical engineering and manufacturing industries.

Current Use

Primarily used in North American electrical engineering, manufacturing, and quality control applications. Common in industries that follow imperial measurement standards for material resistivity testing and specification.
