Candela was chosen so that the new definition would precisely match the old definition. Although the candela is now defined in terms of the second (an SI base unit) and the watt (a derived SI unit), the candela remains a base unit of the SI system, by definition. If a source emits a known luminous intensity "I" (in candelas) in a well-defined cone, the total luminous flux "Φ" in lumens is given by where "A" is the "radiation angle" of the lamp—the full vertex angle of the emission cone. For example, a lamp that emits 590 cd with a radiation angle
Measure for Measure Measure for Measure Measure for Measure is a play by William Shakespeare, believed to have been written in 1603 or 1604. Originally published in the "First Folio" of 1623, where it was listed as a comedy, the play's first recorded performance occurred in 1604.
