WebFold change is a measure describing how much a quantity changes between an original and a subsequent measurement. It is defined as the ratio between the two quantities; for quantities A and B the fold change of B with respect to A is B/A.In other words, a change from 30 to 60 is defined as a fold-change of 2.
