A flux density of one Wb/m 2 (one weber per square metre) is one tesla.
One tesla is equal to one weber per square metre.

### Magnetic flux

fluxfluxes definition of flux used in electromagnetism
In physics, the weber ( symbol: Wb) is the SI derived unit of magnetic flux. The weber may be defined in terms of Faraday's law, which relates a changing magnetic flux through a loop to the electric field around the loop.
The SI unit of magnetic flux is the weber (Wb) (in derived units: volt \cdot seconds), and the CGS unit is the maxwell.

H = henry,
If a current of 1 ampere flowing through the coil produces flux linkage of 1 weber turn, the coil has a self inductance of 1 henry.‌ The unit is named after Joseph Henry (1797–1878), the American scientist who discovered electromagnetic induction independently of and at about the same time as Michael Faraday (1791–1867) in England.

### International Electrotechnical Commission

IECInternational Electrotechnical Commission (IEC)(IEC)
The International Electrotechnical Commission began work on terminology in 1909 and established Technical Committee 1 in 1911, its oldest established committee, "to sanction the terms and definitions used in the different electrotechnical fields and to determine the equivalence of the terms used in the different languages."
The IEC was instrumental in developing and distributing standards for units of measurement, particularly the gauss, hertz, and weber.

### Magnetic field

In 1930, TC1 decided that the magnetic field strength (H) is of a different nature from the magnetic flux density (B), and took up the question of naming the units for these fields and related quantities, among them the integral of magnetic flux density.
(magnetic flux) is measured in webers (symbol: Wb) so that a flux density of 1 Wb/m 2 is 1 tesla.

### Maxwell (unit)

maxwellMx
Mx = maxwell. In 1935, TC 1 recommended names for several electrical units, including the weber for the practical unit of magnetic flux (and the maxwell for the CGS unit).
In 1933, the Electric and Magnetic Magnitudes and Units committee of the International Electrotechnical Commission recommended to adopt the metre-kilogram-second (MKS) system (Giorgi system), and the name weber was proposed for the practical unit of magnetic flux (

This "led eventually to the universal adoption of the Giorgi system, which unified electromagnetic units with the MKS dimensional system of units, the whole now known simply as the SI system (Système International d'unités)."

Three other base units (cd, A, mol) and 17 derived units (N, Pa, J, W, C, V, F, Ω, S, Wb, T, H, kat, Gy, Sv, lm, lx) in the SI system were defined in relation to the kilogram, and thus its stability was important.
