millitesla to microtesla formula
Milli is 10^-3 and micro is 10^-6. They are three powers of ten apart, so every mT to µT conversion uses the exact factor 1,000.
µT = mT × 1,000
50 mT × 1,000 = 50,000 µTmT to µT table

Understanding milliteslas and microteslas
A millitesla (mT) is 10⁻³ of the base unit (tesla) and a microtesla (µT) is 10⁻⁶. They sit three powers of ten apart, so going from mT to µT means multiplying by exactly 1,000 — move the decimal point three places to the right.
Milliteslas cover permanent magnets, motor air gaps and magnetic-field exposure limits. A refrigerator magnet is roughly 5 mT at its surface, and the 0.5 mT line is the conventional safety boundary for pacemakers around MRI hardware.
This calculator shifts the decimal exponent rather than multiplying in binary floating point, so 50 mT returns exactly 50,000 µT — not a value with a trailing rounding error.
Common mT to µT mistake
Gauss is still common in magnet catalogues: 1 mT = 10 G, so a magnet listed at 3000 G is 300 mT. Reading gauss as if it were µT or mT misplaces the value by a factor of ten or ten thousand.
When to use mT vs µT
milliteslas and microteslas are used for medical MRI measurements, geomagnetic fields, sensor calibration, and biomagnetism. Use the larger milli unit when the number becomes easier to scan, and the smaller micro unit when you need finer detail.
