PROBLEM: original question: How many units of length are there in the [International System of Units]?
answer: 11
answer type: Unit of Length.
auxiliary information: The International System of Units is the modern form of the metric system and is the world's most widely used system of measurement, used in both commerce and science. It comprises a coherent system of units of measurement built on seven base units. It defines twenty-two named units, and includes many more unnamed coherent derived units. The system also establishes a set of twenty prefixes to the unit names and unit symbols that may be used when specifying multiples and fractions of the units. The system was published in 1960 as the result of an initiative that started in 1948. It is based on the metre-kilogram-second system of units rather than any variant of the centimetre‚Äìgram‚Äìsecond system. SI is intended to be an evolving system, so prefixes and units are created and unit definitions are modified through international agreement as the technology of measurement progresses and the precision of measurements improves. The 25th General Conference on Weights and Measures in 2014, for example, discussed a proposal to change the definition of the kilogram.
