Another slightly different way to calculate it is to take the difference between the highest and lowest score. The term is usually encountered when dealing with pulse signals although analog K-factors are sometimes used. Once the meter factor is determined it is used as a volume correction in the calculation for net standard volume of a receipt or delivery of liquids. Each calibration or response factor represents the slope of the line between the response for a given standard and the origin. Maybe you've received a calibration certificate for your instrument and noticed that it mentions something like "reported at k=2" at the bottom of the certificate?
