Amperes per Metre to Amperes per Centimetre (A/m to A/cm)
1 ampere per metre (A/m) = 0.01 amperes per centimetre (A/cm). 1 A/cm = 100 A/m. Example: 15 A/m = 15 × 0.01 = 0.15 A/cm.

How to Convert Ampere per Metre to Ampere per Centimetre
- 1 A/m = 0.01 A/cm
- 1 A/cm = 100 A/m
- Example: convert 15 A/m to A/cm: 15 A/m = 15 × 0.01 A/cm = 0.15 A/cm
Formula
A/cm = A/m ÷ 100
Derivation from SI units:
- The SI unit of magnetic field strength H
- 1 A/cm = 100 A/m
Both units are defined exactly, so the factor is exact. Ampere per Metre definition: ampere per metre; Ampere per Centimetre definition: ampere per centimetre.
Worked examples
- A reading of 80 A/m converts to 0.8 A/cm.
80 A/m × 0.01 = 0.8 A/cm - A value of 1000 A/m is 10 A/cm.
1000 A/m × 0.01 = 10 A/cm

Where it's used
Amperes per Metre are used for coil and solenoid design, while amperes per centimetre appear in magnetic particle inspection (tangential field, for example 20–60 A/cm). Both measure magnetic field strength (H field) and coercivity, so the conversion is a fixed factor.

Frequently asked questions
How many amperes per centimetre are in 1 ampere per metre?
1 A/m = 0.01 A/cm.
How do I convert amperes per metre to amperes per centimetre?
Multiply the value in A/m by 0.01, or divide it by 100. For example, 15 A/m × 0.01 = 0.15 A/cm.
Is the A/m to A/cm conversion exact?
Yes. Both units are defined exactly, and 1 A/m is exactly 0.01 A/cm.
