Magnetic Conversion Factors

To convert from SI units to cgs units for use in GM-SYS, use the conversion table below. For example, divide magnetization reported in A/m by 10³ for input into GM-SYS.

Conversion Factors
Quantity cgs unit SI Unit Conversion
Magnetic field (B) gauss (G) tesla (T) 1 gauss=0.0001 T
" gamma [1] nanotesla (nT) [2] 1 gamma [1] = 1 nT [2]
Field intensity (H) oersted (Oe)A/m 1 oersted = 10³ / 4 A/m
Magnetization (M) gauss [3] (G) A/m 1 gauss [3] = 10³ A/m
Susceptibility ( or S) dimensionless dimensionless 1 (cgs) = 4 (SI)
Koenigsberger ratio (Q) dimensionless dimensionless 1 (cgs) = 1 (SI)
[1] 1 gamma = 10-5 gauss
[2] 1 nanotesla = 10-9 tesla
[3] Also called emu/cm³.
