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.

Microhm Inch

μΩ·in

Definition

An imperial unit for very low electric resistivity equal to 2.5400000000102E-8 ohm meters. Used for precision measurements of highly conductive materials in imperial measurement systems.

History/Origin

Developed as an imperial equivalent to microhm centimeter for precision resistivity measurements. Used in North American industries where imperial units are preferred for high-precision electrical measurements.

Current Use

Used in North American precision electrical engineering and manufacturing for measuring highly conductive materials. Common in aerospace, automotive, and electronics industries that require imperial unit precision.
