How It Works

How to Convert Tesla to Gauss

Formula

Gauss = Tesla x 10,000

The Tesla (T) and Gauss (G) both measure magnetic flux density. The Tesla is the SI unit while the Gauss belongs to the CGS system. One Tesla is exactly 10,000 Gauss. The relationship arises because 1 T = 1 Wb/m² and 1 G = 1 Mx/cm², with the area ratio of 10,000 cm² per m² producing the conversion factor.

Worked Example

Convert 0.5 Tesla to Gauss.

tesla = 0.5
  1. 01Apply the conversion factor: 1 T = 10,000 G
  2. 02Gauss = 0.5 * 10,000 = 5,000 G
  3. 03Also: 0.5 T = 500 mT

Frequently Asked Questions

Why are there two units for magnetic field?

The Gauss comes from the older CGS system of units. The Tesla is the SI standard adopted internationally. Both measure magnetic flux density (B-field), with 1 T = 10,000 G.

What magnetic field strength is dangerous?

Static fields below about 8 T are generally considered safe for short exposure. MRI machines operate at 1.5 to 7 T. Very strong fields above 10 T require special safety protocols.

How does this differ from magnetic field intensity (H)?

Tesla measures magnetic flux density (B-field), while Ampere per meter (A/m) measures magnetic field intensity (H-field). They are related by B = mu * H, where mu is the permeability of the medium.
