Convert between magnetic field units: Tesla (T), Gauss (G), microtesla (μT), millitesla (mT), kilogauss (kG), and megagauss (MG). Ideal for MRI, motor design, geophysics, electromagnetic research, and academic studies. Includes conversion formulas, real-world examples, and scientific notation support.
| Conversion | Formula |
|---|---|
| Tesla → Gauss | 1 T = 10⁴ G |
| Gauss → Tesla | 1 G = 10⁻⁴ T |
| mT → Gauss | 1 mT = 10 G |
| μT → Gauss | 1 μT = 0.01 G |
| kG → Tesla | 1 kG = 0.1 T |
| MG → Tesla | 1 MG = 100 T |
The Earth's magnetic field is about 0.5 Gauss.
Tesla: 0.5 × 10⁻⁴ T = 5 × 10⁻⁵ T
Microtesla: 5 × 10⁻⁵ T = 50 μT
A typical MRI scanner uses a 1.5 Tesla magnet.
Gauss: 1.5 × 10⁴ G = 15,000 G
Kilogauss: 15,000 G ÷ 1,000 = 15 kG
A strong neodymium magnet has a surface field of 12,000 Gauss.
Tesla: 12,000 × 10⁻⁴ T = 1.2 T
Millitesla: 1.2 T × 1,000 = 1,200 mT
High-power pulsed magnets can reach 1 Megagauss.
Gauss: 1 MG = 10⁶ G = 1,000,000 G
Tesla: 1,000,000 G × 10⁻⁴ T/G = 100 T
A magnetic sensor reads 800 microtesla.
Tesla: 800 × 10⁻⁶ T = 8 × 10⁻⁴ T
Gauss: 8 × 10⁻⁴ T ÷ 10⁻⁴ = 8 G

The strongest continuous magnetic field is around 45 T (450,000 G), achieved using hybrid magnets.
Pulsed fields can exceed 100 T (10 MG) for very short durations.
Historical reasons: many older instruments and textbooks use Gauss.
Also, Gauss is more convenient for small fields (e.g., Earth’s field ≈ 0.5 G), while Tesla is better for large fields (e.g., MRI).
Yes! You can input values like 1.5e-5 for 15 microtesla or 3e4 for 30,000 Gauss.
The tool supports real-time bidirectional calculation.
No! 1 μT = 0.01 G
So, 100 μT = 1 G.
Common mistake: people confuse μT and mT.
Most clinical MRI scanners use magnets with fields between 1.5 T and 3.0 T, which equals 15,000 to 30,000 Gauss.
Research MRI systems can go up to 7 T or higher.
Tesla (T) is the SI unit of magnetic flux density.
Gauss (G) is a CGS unit, commonly used in older literature and some industries.
1 T = 10,000 G — so 1 Gauss = 0.0001 Tesla.
