Gauss (unit) symbol is uppercase ("G"), but when the unit is spelled out, it should be written in lowercase ("gauss"), unless it begins a sentence. Gauss (unit) The gauss, abbreviated as G or Gs, is the cgs unit of measurement of magnetic flux density (or "magnetic induction") (B). It is named after German mathematician and physicist Carl Friedrich Gauss. One gauss is defined as one maxwell per square centimeter. The cgs system has been superseded by the International System of Units (SI), which uses the tesla (symbol T) as the unit of magnetic flux density. One gauss equals 1 tesla (100 μT),
Spectral flux density from it only, uncontaminated by radiation from other sources. In this case, spectral flux density is the quantity that describes the rate at which energy transferred by electromagnetic radiation is received from that unresolved point source, per unit receiving area facing the source, per unit wavelength range. At any given wavelength "λ", the spectral flux density, F, can be determined by the following procedure: Spectral flux density is often used as the quantity on the "y"-axis of a graph representing the spectrum of a light-source, such as a star. There are two main approaches to definition of the spectral flux
