Many sensors will provide a range of values from 0 to X, where X might be 4095, 32000, or some other value. 
Those raw values translate to something much smaller in human terms: zero to 100% or -40 to +451 degrees. 
We use scaling to translate the raw machine data to the engineering units being read.
