Unit definition
Tesla (T) One tesla equals 1 tesla.
Unit history
The tesla, named for Nikola Tesla, was adopted as the SI unit of magnetic flux density.
Step by step
1. Parse the value, including fractions.
2. Convert T to tesla.
3. Convert the base value to µT and apply your display precision.
Understand the result before using it
Tesla (T) and microtesla (µT) are units of magnetic flux density. Micro means one millionth, so 1 T = 1,000,000 µT. Multiply the tesla value by 1,000,000 to express the same flux density in microtesla.
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 × 1000000
Assumptions
- Tesla and Microtesla represent the same magnetic flux density quantity.
- The input is expressed in T; the output is expressed in µT.
- The unit definitions and conventional relationship shown on this page apply.
Worked example
For 0.00005 T, multiply 0.00005 by 1,000,000 to get 50 µT. For 0.002 T, calculate 0.002 × 1,000,000 = 2,000 µT.
When to use it
Good uses
- Express a magnetic flux density recorded in T in the µT units used by a table.
- Compare magnetic flux density values after converting them to the same prefix.
Limitations
Common mistakes to avoid
- T and µT describe magnetic flux density. Magnetic flux in webers and field strength in amperes per metre are different quantities.
- Keep the prefix symbols distinct: mT is millitesla and µT is microtesla.
- Conversion changes the unit, not the precision of the original measurement.

Questions about this calculation
How many microtesla are in one tesla?
One tesla equals 1,000,000 microtesla. Multiply a value in T by 1,000,000 to obtain µT.
What is 0.00005 T in µT?
0.00005 T × 1,000,000 = 50 µT.
Are microtesla and millitesla the same?
No. One millitesla (mT) equals 1,000 microtesla (µT). Read the prefix in the original measurement before converting.
