How to Convert Teslas to Milliteslas
The tesla and millitesla are both units of magnetic field. By definition, 1 millitesla equals exactly 1000000 teslas. This means to convert teslas to milliteslas, you divide by 1000000.
Formula
Step-by-Step Example
Convert 5 T to milliteslas:
We need to convert teslas to milliteslas
Since 1 mT = 1000000 T, divide by 1000000
5 ÷ 1000000 = 5e-6
5 T = 5e-6 mT

About These Units
Tesla (T)
The tesla (T) is the SI unit of magnetic flux density (magnetic field strength). Named after Nikola Tesla. MRI machines: 1.5-7 T, neodymium magnet surface: 1-1.4 T, Earth's field: ~50 μT. One tesla = one weber per square meter = 10,000 gauss.
Millitesla (mT)
A millitesla (mT) equals 0.001 teslas or 10 gauss. Common range for permanent magnets: fridge magnet 5 mT, speaker magnet 100-400 mT, hard drive head 10-50 mT. Used in electronics, medical devices, and magnetic sensors.
