Amperes per Metre to Kiloamperes per Metre (A/m to kA/m)
1 ampere per metre (A/m) = 0.001 kiloamperes per metre (kA/m). 1 kA/m = 1000 A/m. Example: 15 A/m = 15 × 0.001 = 0.015 kA/m.

How to Convert Ampere per Metre to Kiloampere per Metre
- 1 A/m = 0.001 kA/m
- 1 kA/m = 1000 A/m
- Example: convert 15 A/m to kA/m: 15 A/m = 15 × 0.001 kA/m = 0.015 kA/m
Formula
kA/m = A/m ÷ 1000
Derivation from SI units:
- The SI unit of magnetic field strength H
- 1 kA/m = 1000 A/m
Both units are defined exactly, so the factor is exact. Ampere per Metre definition: ampere per metre; Kiloampere per Metre definition: kiloampere per metre.
Worked examples
- A reading of 80 A/m converts to 0.08 kA/m.
80 A/m × 0.001 = 0.08 kA/m - A value of 1000 A/m is 1 kA/m.
1000 A/m × 0.001 = 1 kA/m

Where it's used
Amperes per Metre are used for coil and solenoid design, while kiloamperes per metre appear in permanent magnet coercivity (for example 900–2000 kA/m for NdFeB). Both measure magnetic field strength (H field) and coercivity, so the conversion is a fixed factor.

Frequently asked questions
How many kiloamperes per metre are in 1 ampere per metre?
1 A/m = 0.001 kA/m.
How do I convert amperes per metre to kiloamperes per metre?
Multiply the value in A/m by 0.001, or divide it by 1000. For example, 15 A/m × 0.001 = 0.015 kA/m.
Is the A/m to kA/m conversion exact?
Yes. Both units are defined exactly, and 1 A/m is exactly 0.001 kA/m.
