Conversion of Gauss to Tesla:
1µG = 0.1nT, 1mG = 100nT, 1G = 100µT, 10G = 1mT, 10,000G = 1T

Relationship between Magnetic Flux Density (B) and Magnetic Field Strength (H):
In vacuum (or air) B=µoH. For SI units µo = 4pi x 10-7H/m, B is expressed in Tesla and H in Ampere turn/m or A/m. Hence in vacuum or air a flux density of 1T = 796kA/m.
For cgs units µo = 1, B is expressed in gauss and H in oersted. Hence in vacuum or air a flux density of 1 gauss = 1 oersted.
