It is not an SI unit, but rather is associated with the older centimetre gram second system of units. The name was coined by André Blondel in 1921.〔Parry Moon. "System of photometer concepts", in the ''Journal of the Optical Society of America'', volume 32, number 6 (June 1942). – Page 355: "The lumen was proposed by Blondel in 1894 and is now universally accepted. The names, phot and stilb were likewise coined by Blondel (1921) and are in general use on the Continent."〕 Metric equivalence: :$1\backslash \; \backslash mathrm\; =\; 1\backslash \; \backslash frac^2\}\; =\; 10,000\backslash \; \backslash frac^2\}\; =\; 10,000\backslash \; \backslash mathrm\; =\; 10\backslash \; \backslash mathrm$ Metric dimensions: :illuminance = luminous intensity × solid angle / length2 == See also == *Illuminance *Lumen (unit) *Lux *Photometry (optics) *Light 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Phot」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
