n. the SI derived unit of magnetic flux density, equal to one weber per square metre. When used as a unit of measurement, it is not capitalised, though its symbol (T) is.
The MRI machine uses a powerful three tesla magnet.
In high-energy physics experiments, superconducting magnets are often pushed to several teslas to steer particle beams at nearly the speed of light.
Usage
The unit name is written in lowercase (tesla) when spelled out, but the symbol is a capital T.
Pitfall
The field was 5 Tesla.The field was 5 teslas.When referring to the unit of measurement in the plural, it should be lowercase and take an 's'.
