Unit history
Microtesla 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 µT to tesla.
3. Convert the base value to mT and apply your display precision.
Understand the result before using it
Microtesla to Millitesla converts a value measured in Microtesla (µT) into the equivalent value in Millitesla (mT). 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 × 0.000001 ÷ 0.001
Assumptions
- Microtesla and Millitesla represent the same magnetic flux density quantity.
- The input is expressed in µT; the output is expressed in mT.
- The unit definitions and conventional relationship shown on this page apply.
Worked example
1 µT = 0.001 mT. 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 µT measurement in a document that expects mT.
- Compare a microtesla value with a value reported in millitesla.
- Check the µT-to-mT arithmetic before copying the result into another calculation.
Limitations
Common mistakes to avoid
- Do not confuse µT 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.
