    Luminance 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, is emitted or reflected from a particular area, and falls within a given solid angle. The SI unit for luminance is candela per square metre (cd/m2).

NEPER public static final javax.measure.Unit<javax.measure.quantity.Dimensionless> NEPER A dimensionless unit accepted for use with SI units (standard name Np). Although the neper is coherent with SI units and is accepted by the CIPM, it has not been adopted by the General Conference on Weights and Measures (CGPM, Conférence Générale des Poids et Mesures) and is thus not an SI unit. BEL public static final javax.measure.Unit<javax.measure.quantity.Dimensionless> BEL A dimensionless unit accepted for use with SI units (standard name B). The bel is most commonly used with the SI prefix deci: 1 dB = 0.1 B ELECTRON_VOLT public static final javax.measure.Unit<javax.measure.quantity.Energy> ELECTRON_VOLT An energy unit accepted for use with SI units (standard name eV). The electronvolt is the kinetic energy acquired by an electron passing through a potential difference of 1 V in vacuum. The value must be obtained by experiment, and is therefore not known exactly. UNIFIED_ATOMIC_MASS public static final javax.measure.Unit<javax.measure.quantity.Mass> UNIFIED_ATOMIC_MASS A mass unit accepted for use with SI units (standard name u). The unified atomic mass unit is equal to 1/12 of the mass of an unbound atom of the nuclide 12C, at rest and in its ground state. The value must be obtained by experiment, and is therefore not known exactly. ASTRONOMICAL_UNIT public static final javax.measure.Unit<javax.measure.quantity.Length> ASTRONOMICAL_UNIT A length unit accepted for use with SI units (standard name UA). The astronomical unit is a unit of length. Its value is such that, when used to describe the motion of bodies in the solar system, the heliocentric gravitation constant is (0.017 202 098 95)2 ua3·d-2. The value must be obtained by experiment, and is therefore not known exactly. REVOLUTION public static final javax.measure.Unit<javax.measure.quantity.Angle> REVOLUTION An angle unit accepted for use with SI units (standard name rev). HECTARE public static final javax.measure.Unit<javax.measure.quantity.Area> HECTARE An angle unit accepted for use with SI units (standard name ha).
