Convert Microtesla to Tesla (µT to T)
1 microtesla (µT) = 0.000001 tesla (T). 1 T = 1000000 µT. Example: 15 µT = 15 × 0.000001 = 0.000015 T.

How to Convert Microtesla to Tesla
- 1 µT = 0.000001 T
- 1 T = 1000000 µT
- Example: convert 15 µT to T: 15 µT = 15 × 0.000001 T = 0.000015 T
Formula
T = µT ÷ 1000000
Derivation from SI units:
- 1 µT = 10⁻⁶ T
- 1 T = 1 Wb/m² = 1 kg/(s²·A), the SI unit of magnetic flux density
Both units are defined exactly, so the factor is exact. Microtesla definition: microtesla; Tesla definition: tesla.
Worked examples
- A reading of 1 µT converts to 0.000001 T.
1 µT × 0.000001 = 0.000001 T - A value of 25 µT is 0.000025 T.
25 µT × 0.000001 = 0.000025 T

Where it's used
Microtesla are used for earth’s magnetic field and compasses, while tesla appear in MRI scanners (1.5 T and 3 T). Both measure magnetic flux density (B field), so the conversion is a fixed factor.

Frequently asked questions
How many tesla are in 1 microtesla?
1 µT = 0.000001 T.
How do I convert microtesla to tesla?
Multiply the value in µT by 0.000001, or divide it by 1000000. For example, 15 µT × 0.000001 = 0.000015 T.
Is the µT to T conversion exact?
Yes. Both units are defined exactly, and 1 µT is exactly 0.000001 T.
