original question: What is the unit of luminance in measurement system [Centimetre‚Äìgram‚Äìsecond system of units]?
answer: stilb
answer type: Unit of Luminance.
auxiliary information: The centimetre‚Äìgram‚Äìsecond system of units is a variant of the metric system based on the centimetre as the unit of length, the gram as the unit of mass, and the second as the unit of time. All CGS mechanical units are unambiguously derived from these three base units, but there are several different ways of extending the CGS system to cover electromagnetism. The CGS system has been largely supplanted by the MKS system based on the metre, kilogram, and second, which was in turn extended and replaced by the International System of Units. In many fields of science and engineering, SI is the only system of units in use but there remain certain subfields where CGS is prevalent. In measurements of purely mechanical systems, the differences between CGS and SI are straightforward and rather trivial; the unit-conversion factors are all powers of 10 as 100 cm = 1 m and 1000 g = 1 kg. For example, the CGS unit of force is the dyne which is defined as 1 g¬∑cm/s¬≤, so the SI unit of force, the newton, is equal to 100,000 dynes. On the other hand, in measurements of electromagnetic phenomena, converting between CGS and SI is much more subtle and involved.
The [Centimetre‚Äìgram‚Äìsecond system of units] measurement system uses what unit of luminance?
