Convert Gauss to Microtesla (G to µT)
1 gauss (G) = 100 microtesla (µT). 1 µT = 0.01 G. Example: 15 G = 15 × 100 = 1500 µT.

How to Convert Gauss to Microtesla
- 1 G = 100 µT
- 1 µT = 0.01 G
- Example: convert 15 G to µT: 15 G = 15 × 100 µT = 1500 µT
Formula
µT = G × 100
Derivation from SI units:
- 1 G = 10⁻⁴ T (exact)
- 1 µT = 10⁻⁶ T
- 1 G = 0.0001 T ÷ 0.000001 T per µT = 100 µT
Both units are defined exactly, so the factor is exact. Gauss definition: gauss; Microtesla definition: microtesla.
Worked examples
- A reading of 50 G converts to 5000 µT.
50 G × 100 = 5000 µT - A value of 5000 G is 500000 µT.
5000 G × 100 = 500000 µT

Where it's used
Gauss are used for permanent magnet surface fields (for example 3000–5000 G for neodymium), while microtesla appear in earth’s magnetic field and compasses. Both measure magnetic flux density (B field), so the conversion is a fixed factor.

Frequently asked questions
How many microtesla are in 1 gauss?
1 G = 100 µT.
How do I convert gauss to microtesla?
Multiply the value in G by 100. For example, 15 G × 100 = 1500 µT.
Is the G to µT conversion exact?
Yes. Both units are defined exactly, and 1 G is exactly 100 µT.
