Percent IACS to ohm-meters
Type a value in %IACS to get it in Ω·m instantly.
1.724Ω·m
That's 8.6× as conductive as seawater, while pure silicon is 371× higher. A meter of 1 mm² wire made of it would have about 1,724,000 Ω of resistance.
Convert the other way: Ω·m to %IACS
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 %IACS to Ω·m
%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 %IACS = 1.7241 Ω·m.
