Unit definition
Millitesla (mT) One millitesla equals 0.001 tesla.
Unit history
Millitesla is represented here using its modern SI definition or an internationally accepted relationship to an SI base unit.
Step by step
1. Parse the value, including fractions.
2. Convert mT to tesla.
3. Convert the base value to µT and apply your display precision.
Understand the result before using it
Millitesla to Microtesla converts a value measured in Millitesla (mT) into the equivalent value in Microtesla (µT). The numerical value changes because the size and definition of the selected unit changes; the underlying quantity does not.
Calculated result
The conversion follows the displayed unit relationship. Display rounding can hide additional digits, and measured inputs cannot become more accurate merely by changing units.
Formula, assumptions, and example
Formula
result = input × 0.001 ÷ 0.000001
Assumptions
- Millitesla and Microtesla represent the same magnetic flux density quantity.
- The input is expressed in mT; the output is expressed in µT.
- The unit definitions and conventional relationship shown on this page apply.
Worked example
1 mT = 1,000 µT. For another value, apply the same relationship and round only to the precision your source measurement supports.
When to use it
Good uses
- Read a mT measurement in a document that expects µT.
- Compare a millitesla value with a value reported in microtesla.
- Check the mT-to-µT arithmetic before copying the result into another calculation.
Limitations
Common mistakes to avoid
- Do not confuse mT with another unit that has a similar name or symbol.
- Round the output to a precision justified by the original measurement.
- Verify safety-critical, regulated, laboratory, and contractual conversions against the controlling standard.
