Convert magnetic field unit values easily
Result: -
Magnetic fields are everywhere — from Earth’s protective shield to smartphones, medical scanners, transformers, and electric motors. Yet, measuring magnetism isn't always straightforward. Scientists and engineers use different units depending on industry standards, region, and measurement purpose.
The Free Magnetic Field Unit Converter by AlllinTools allows accurate conversion between magnetic field strength, magnetic flux density, and related physics units such as:
Tesla (T) — SI unit for magnetic flux density
Gauss (G) — Common in legacy scientific applications
Millitesla (mT) & Microtesla (µT) — Low-intensity fields
Oersted (Oe) — Magnetic field strength in CGS system
Ampere per meter (A/m) — Used in electromagnetics & material science
Precision matters — whether designing MRI machines or calibrating tiny sensors.
When magnetism is measured correctly, technology performs safely and efficiently.
Magnetic field values impact performance, safety, and compatibility in many industries. Incorrect conversions may result in:
❌ Faulty sensors or incorrect calibration
❌ Weak motor performance
❌ Transformer overheating & energy loss
❌ Misinterpretation in scientific studies
❌ Unsafe EMI (Electromagnetic Interference) exposure levels
Correct magnetic measurement ensures:
✔ Efficient energy transfer
✔ Safe electronic environments
✔ Accurate medical diagnosis
✔ Reliable navigation and sensors
✔ Stable industrial automation
Where magnetism exists — conversion is required.
| Measurement | Unit | Symbol | Usage |
|---|---|---|---|
| Magnetic flux density | Tesla | T | Motors, electronics, MRI |
| Magnetic flux density (legacy) | Gauss | G | Geophysics, early magnetism studies |
| Field strength | Ampere per meter | A/m | Coil design, magnetic materials |
| Field strength (CGS) | Oersted | Oe | Magnet fabrication and testing |
📌 Tesla ↔ Gauss
1 Tesla = 10,000 Gauss
1 Gauss = 0.0001 Tesla
📌 Tesla ↔ Millitesla
1 T = 1000 mT
📌 Tesla ↔ Microtesla
1 T = 1,000,000 µT
📌 Oersted ↔ A/m
1 Oersted ≈ 79.57747 A/m
Example:
Permanent magnet strength: 0.5 T
→ 5,000 Gauss
→ 500 mT
All conversions handled instantly by AlllinTools with precise scientific constants.
| Field Strength | Equivalent | Source / Effect |
|---|---|---|
| 50 µT | ~0.5 G | Earth’s magnetic field (surface average) |
| 1–2 mT | 10–20 G | Small fridge magnets |
| 0.3–3 T | 3000–30,000 G | MRI scanners |
| 45 T | 450,000 G | Lab high-field research magnets |
