Electrical conductivity of water samples is used as an indicator of how salt-free, ion-free, or impurity-free the sample is; the purer the water, the lower the conductivity (the higher the resistivity). Conductivity measurements in water are often reported as specific conductance, relative to the conductivity of pure water at 25 °C.

Let K 0 is the normal conductivity at one bar (10 5 N/m 2) pressure, K e is its conductivity at special pressure and/or length scale. Let d is a plate distance in meters, P is an air pressure in Pascals (N/m 2 ), T is temperature Kelvin, C is this Lasance constant 7.6 ⋅ 10 −5 m ⋅ K/N and PP is the product P ⋅ d/T .

Charge carrier densities involve equations concerning the electrical conductivity, ... Copper: 1 8.47 × 10 22: Silver: 1 5.86 × 10 22: Gold: 1
The electrical conductivity of 6-nines copper and 4-nines copper (99.99% pure) is nearly the same at ambient temperature, although the higher-purity copper has a higher conductivity at cryogenic temperatures. Therefore, for non-cryogenic temperatures, 4-nines copper will probably remain the dominant material for most commercial wire ...
Copper's superior conductivity enhances the efficiency of electrical motors. [135] This is important because motors and motor-driven systems account for 43–46% of all global electricity consumption and 69% of all electricity used by industry. [136] Increasing the mass and cross section of copper in a coil increases the efficiency of the motor.
The International Annealed Copper Standard (IACS) is a standard established in 1914 by the United States Department of Commerce. [1] It is an empirically derived standard value for the electrical conductivity of commercially available copper .
