Ohm-meters to percent IACS
Type a value in Ω·m to get it in %IACS instantly.
1.724%IACS
That's 7× as conductive as steel, while seawater is 200,000× higher. A meter of 1 mm² wire made of it would have about 1 Ω of resistance.
Convert the other way: %IACS to Ω·m
What it means
How well does it conduct?
Resistivity rises with temperature for metals and falls for semiconductors. Published values are at 20 °C unless stated otherwise.
The math
How to convert Ω·m to %IACS
%IACS is a reciprocal: %IACS = 1.7241 × 10⁻⁸ ÷ ρ × 100 with ρ in ohm-meters, so a better conductor has a higher percentage and a lower resistivity. The rest are plain multiples.
Example: 1×10⁻⁶ Ω·m = 1.7241 %IACS.
