UnitConMagnetic Flux Density
Magnetic flux density, written B, measures magnetic field per unit area. It is measured in tesla in SI and gauss in CGS, and it appears in applications ranging from MRI systems to motors and sensors. This converter helps compare weak fields such as Earth's with strong engineered magnets. It is useful for both education and technical reference.
Common conversions
| From | To |
|---|---|
| 1 Tesla | 10,000 Gauss |
| 50 Microtesla | 0.5 Gauss |
| 1 Millitesla | 10 Gauss |
| 1000 Gauss | 0.1 Tesla |
| 1 Nanotesla | 0.001 Microtesla |
Frequently asked questions
Magnetic flux density describes how strong a magnetic field is over an area. It is one of the most common ways to quantify magnetic field magnitude.
Tesla is the SI unit and gauss is the CGS unit. One tesla equals 10,000 gauss.
Clinical MRI systems commonly operate around 1.5 to 3 tesla. That is far stronger than Earth's magnetic field.
Earth's field is typically on the order of tens of microtesla. The exact value depends on location and local geology.
