The oldest scale, Balling (°Balling), was developed in 1843 by Bohemian scientist Karl Joseph Napoleon Balling (1805–1868) and Simon Ack. In the 1850s, German engineer-mathematician Adolf Ferdinand Wenceslaus Brix (1798–1870) corrected some of the calculation errors in the Balling scale and introduced the Brix scale. In the early 1900s German chemist Fritz Plato (1858–1938) and his collaborators made further improvements, introducing the Plato scale. Essentially the Balling, Brix, and Plato scales are all the same scale, with improvements in accuracy and reliability in the newer versions, since they are all based on mass fraction of sucrose; the tables for the three scales differ mainly in their precision and in the temperature at which the measurements are to be made.
