Task: Class Definition Understanding (ontology: Earth_Environment/OBOE)

Which of the following definitions best describes 'BarToKilopascal'?

A. A the concept defines a reference for comparing or naming entities via a measurement. A the concept can be defined intentionally (e.g., as in the case of units) or extensionally (by listing the values of the the concept, e.g., for color this might be red, blue, yellow, etc).
B. A the concept raises a base or prefixed unit to an integer power other than 0 or 1. For example, the unit 'square meter' is a unit derived from the 'meter' base unit raised to the power 2. As another example, a 'square centimeter' is a unit derived from the 'centimeter' prefixed unit raised to the power 2.

BRL 20160601: I removed this restriction so that CompositeUnits like XXXPerLiter would not reason to owl:Nothing. hasUnit exactly 1 (BaseUnit or PrefixedUnit)
C. the concept is a photometric measure of the luminous intensity per unit area of light travelling in a given direction. It describes the amount of light that passes through or is emitted from a particular area, and falls within a given solid angle. The SI unit for the concept is candela per square metre (cd/m2).
D. The bar (symbol: bar) is a unit of pressure equal to 100 kilopascals, and roughly equal to the atmospheric pressure on Earth at sea level.

Answer: The bar (symbol: bar) is a unit of pressure equal to 100 kilopascals, and roughly equal to the atmospheric pressure on Earth at sea level.
