How many gauss are in one microtesla?

One microtesla equals 0.01 G. The formula is G = µT × 0.01.

How do I convert microteslas to gauss?

Multiply the value in microteslas by 0.01. For example, 100 × 0.01 = 1 — so 100 µT = 1 G.

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.
