No, Tesla is not an SI unit in the sense that it is not a fundamental unit like meter or kilogram. However, it is an SI unit. The **Tesla (T)** is the unit of magnetic flux density or magnetic induction, and it is named after the inventor and electrical engineer **Nikola Tesla**.
In the SI system:
- 1 Tesla is equal to 1 **weber per square meter** (Wb/m²).
- It measures the strength of a magnetic field, and it is used to describe how strong or intense the magnetic field is in a given area.
So, while Tesla is indeed part of the SI system, it specifically relates to magnetism, not something more fundamental like length or mass.
