Convert Amperes per metre to Milliamperes per metre
Convert Amperes per metre (A/m) to Milliamperes per metre (mA/m) instantly and accurately.
Conversion Formula
mA/m = A/m × 1000
About Amperes per metre
The ampere per metre (A/m) is the SI coherent unit of magnetic field strength H, expressing the magnetomotive force per unit length. It defines how strongly a field drives magnetic flux through a material. Earth's geomagnetic H field is approximately 40-60 A/m; a typical transformer core operates at 100-1000 A/m. 1 A/m = 1 A m⁻¹.
About Milliamperes per metre
The milliampere per metre (mA/m) equals 10⁻³ A/m. Antenna near-field H-field measurements and EMC pre-compliance tests use mA/m; CISPR 14/16 and FCC Part 15 limit radiated field strength for consumer electronics in mA/m or equivalent dBµA/m at specified distances. 1 mA/m = 10⁻³ A/m = 10⁻³ Oe × (1000/4π).
