What is Gauss? Gauss is a unit of measurement used to describe both the coercivity of a magnet and its saturation magnetization. Basically, it describes how strong the magnetic fields are extending from the magnet and how strong of a magnetic field it would take to de-magnetize the magnet. The name comes from the mathematician physicist Carl Freidrich Gauss.
What are BTUs? BTUs are âBritish Thermal Unitsâ, the unit in which radiator efficiency is measured. Factors such as room dimensions, window size and wall material are used to calculate the required outputs of radiators, in order to adequately heat a room. The best way to get an accurate calculation is to enlist the services of a plumber.
