About Electric Resistivity Units

Electric resistivity (also known as specific electrical resistance) is a fundamental property of a material that quantifies how strongly it opposes the flow of electric current. It is the inverse of electrical conductivity and is independent of the material's size and shape.

Common Electric Resistivity Units

• Ohm-meter (Ω·m): The SI unit of electric resistivity, representing the resistance of a uniform material with a cross-sectional area of 1 square meter and a length of 1 meter.
• Ohm-centimeter (Ω·cm): A commonly used unit in materials science, equal to 0.01 ohm-meters.
• Microohm-centimeter (μΩ·cm): Used for materials with low resistivity, equal to 10^-8 ohm-meters.
• Microohm-inch (μΩ·in): Used in some industries, particularly in the United States, equal to 2.54 × 10^-8 ohm-meters.
• Ohm-circular mil per foot (Ω·cmil/ft): A unit commonly used in the wire industry, particularly in North America.

Applications of Electric Resistivity Measurement

Electric resistivity measurements are important in various fields including:

• Materials science and engineering
• Semiconductor manufacturing
• Cable and wire design
• Geophysics for subsurface exploration
• Quality control in metallurgy
• Corrosion monitoring
