Frequently Asked Questions
Common questions about Magnetic Field & Flux Density Converter units, conversions, and formulas.
1 Tesla (T) equals exactly 10,000 Gauss (G). Therefore, 1 Gauss equals 100 microteslas (100 μT or 0.0001 T).
Earth's geomagnetic field ranges from approximately 25 to 65 microteslas (0.25 to 0.65 Gauss) at the surface, depending on geographic location.
B is magnetic flux density measured in Tesla (SI) or Gauss (CGS), while H is magnetic field strength measured in Ampere per meter (A/m) or Oersteds (Oe). In a vacuum, B = μ0 × H, where μ0 is the vacuum magnetic permeability (4π × 10⁻⁷ H/m).
