Celsius
subject			fact

Celsius	documentation A ThermodynamicTemperatureMeasure. Kelvin differs from the Celsius scale in that the triple point of water is defined to be 273.16 degrees Kelvin while it is 0 degrees Celsius. The boiling point of water is 100 degrees Celsius. The magnitudes of intervals in the two scales are the same. By definition the conversion constant is 273.1
	has axiom (equal (MeasureFn ?NUMBER Celsius) (MeasureFn (SubtractionFn ?NUMBER 273.15) Kelvin))
	is an instance of SystemeInternationalUnit
	is an instance of ThermodynamicTemperatureMeasure
UnitOfMeasure	is second domain of MeasureFn
ConstantQuantity	is first domain of MagnitudeFn
	is second domain of measure
PhysicalQuantity	is partitioned into ConstantQuantity, FunctionQuantity
Abstract	is disjoint from Physical
