When we talk about the magnetic field, different units are used to measure it. Basically, there are two systems of units based on the metric system used: the SI unit and CGS units. Thus, we will look at the unit of magnetic field below.
SI Unit of Magnetic Field
Generally, the magnetic field can be defined in several specific ways in relation to its effect on the environment. Accordingly, we have the B-field and the H-field. B-field is a magnetic field defined by the force it exerts on a moving charged particle, whereas an H-field is similar to a B-field except when they are inside a material. However, they are measured differently.
In the SI System:
- B is measured in teslas represented as T.
- Whereas the H-field is measured in amperes per metre (A/m).

Other Common Units
Some other common unit of Magnetic Field is given below:
- Apart from the SI system, the B-field in the Gaussian-CGS system is measured with the unit gauss (G).
- If we look at the conversion it is 1 T = 10000 G.
- Meanwhile, the H-field is measured with the help of Oersted (Oe) in the CGS system.
