A non-SI unit of energy is the calorie -another way of indicating the amount of chemical energy in a material. One medium potato has 110,000 calories as determined by laboratory measurement (the potato is completely burned with oxygen and the energy released is measured). However, if an internet search is carried out, one potato producer's web site shows this potato to contain 110 Calories (equivalent to the 110,000 "regular" calories). Why would they list the smaller number instead of the scientifically correct one?
