%IACS Conductivity Converter
Copper-industry %IACS ↔ MS/m ↔ resistivity.
The 1913 'International Annealed Copper Standard' froze 100% at 58 MS/m — modern OFHC copper beats it at 101–102%. Eddy-current NDT sorts alloys by this number in seconds.
Formula
%IACS Conductivity Converter is a free iacs conversion for design engineers, metallurgists and QA inspectors — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.

Frequently asked questions
What formula does the %IACS Conductivity Converter use?+
It computes 100 %IACS = 58 MS/m = 1.7241 µΩ·cm, per IACS (1913); ASTM B193. The formula is displayed under the result along with a worked example substituted with your own inputs.
What should I keep in mind when using this calculator?+
The 1913 'International Annealed Copper Standard' froze 100% at 58 MS/m — modern OFHC copper beats it at 101–102%. Eddy-current NDT sorts alloys by this number in seconds.
Where do the material property defaults come from?+
Defaults are standard handbook values (ASM, manufacturer datasheets, the cited standard). Always substitute certified values from your material's test certificate for critical work.
Is the %IACS Conductivity Converter free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
