Convert Amperes per foot (A/ft) to Amperes per centimetre (A/cm) instantly and accurately.
Conversion Formula
A/cm = A/ft × 0.03280839895
About Amperes per foot
The ampere per foot (A/ft) equals 1/0.3048 A/m ≈ 3.281 A/m. Used in US electromagnetic coil design and transformer winding specifications where dimensions are in feet; older US Navy and DoD magnetic shielding specifications for shipboard demagnetisation state H values in A/ft. 1 A/ft = 1/0.3048 A/m ≈ 3.2808 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.
