The Tesla (T) is the SI (International System of Units) unit of magnetic flux density, named after inventor Nikola Tesla. One Tesla represents a very strong magnetic field: for context, Earth's magnetic field is only about 50 microtesla (0.00005 T), while a typical refrigerator magnet produces around 0.005 T. Medical MRI machines generate fields from 0.5 to 7 Tesla, and research superconducting magnets can exceed 20 Tesla. Because the Tesla represents such a powerful field strength, laboratory measurements often use smaller units like millitesla (mT) for convenience. The Tesla is defined as one weber per square meter, relating magnetic flux to area, making it fundamental to electromagnetic theory and practical applications.
Converting Tesla to millitesla is a simple metric conversion. Since "milli" means one-thousandth, and we're going from a larger unit (Tesla) to a smaller unit (millitesla), we multiply by 1000.
Example: Convert 1.5 T to mT
1.5 T × 1000 = 1500 mT
Medical professionals specify MRI machine strength in Tesla (typically 1.5 T or 3 T), while detailed field mapping and calibration often use millitesla for precision measurements.
Scientists working with superconducting magnets and particle accelerators frequently convert between Tesla and millitesla when documenting experimental conditions and magnetic field strengths.
Engineers testing magnetic materials and ferromagnetic properties use these conversions to specify applied magnetic fields and measure material responses accurately.
Design engineers working on electric motors, generators, and transformers convert between Tesla and millitesla when calculating magnetic circuit performance and core saturation.
Manufacturing facilities use millitesla measurements for quality assurance testing of magnetic sensors, Hall effect devices, and magnetoresistive components.
One Tesla is extremely strong compared to common magnets. A refrigerator magnet is about 0.005 T (5 mT), and a strong neodymium magnet is around 0.3-1.3 T. Earth's magnetic field is only 0.00005 T (0.05 mT).
Millitesla provides a more convenient scale for many laboratory measurements. Instead of writing 0.350 T, scientists can write 350 mT, which is easier to read and reduces decimal point errors in calculations.
The strongest continuous magnetic field created in a laboratory is over 45 Tesla (45,000 mT). Pulsed magnetic fields have briefly exceeded 100 Tesla, though such extreme fields can destroy the equipment creating them.
Yes, 1 Tesla equals 10,000 Gauss. While Tesla is the SI unit, Gauss is still commonly used in some fields, particularly in the United States. Millitesla equals 10 Gauss.
Yes, the conversion is exact by definition: 1 T = 1000 mT precisely. This is a metric prefix conversion with no approximation or measurement uncertainty involved.
Most clinical MRI machines operate at 1.5 Tesla (1,500 mT) or 3 Tesla (3,000 mT). Research MRI systems can reach 7 Tesla or higher, providing better image resolution but requiring more safety precautions.
