How many teslas are in one gauss?

One gauss equals 0.0001 T. The formula is T = G × 0.0001.

How do I convert gauss to teslas?

Multiply the value in gauss by 0.0001. For example, 100 × 0.0001 = 0.01 — so 100 G = 0.01 T.

Magnetic flux density

Why your fridge magnet is stronger than the Earth

A compass needle points north flawlessly, guiding sailors for centuries — yet the field that steers it is hundreds of times weaker than a cheap magnetic toy on a fridge door. This is a journey across the scale of magnetic flux density: from the quiver of a compass, through the mighty teslas of an MRI scanner, to cosmic magnetars.
