Convert Amperes per inch to Amperes per centimetre
Convert Amperes per inch (A/in) to Amperes per centimetre (A/cm) instantly and accurately.
Conversion Formula
A/cm = A/in × 0.3937007874
About Amperes per inch
The ampere per inch (A/in) equals 1/0.0254 A/m ≈ 39.370 A/m. Standard unit in US magnetic core and inductor datasheets from manufacturers like Magnetics Inc. and Ferroxcube; B-H curves and core loss specifications for powder cores and ferrites are commonly plotted in Oe (H-axis) or A/in in North American catalogs. 1 A/in = 1/0.0254 A/m ≈ 39.37 A/m.
About Amperes per centimetre
The ampere per centimetre (A/cm) equals 100 A/m. Widely used in European and Japanese magnetics datasheets and IEC standards; soft ferrite B-H curves in power electronics applications are frequently plotted with H in A/cm; magnetic core loss characterisation in IEC 60404 uses A/cm for H values. 1 A/cm = 100 A/m = 4π/10 Oe.
