28 year-old Painting Investments Worker Truman from Regina, usually spends time with pastimes for instance interior design, property developers in new launch ec Singapore and writing. Last month just traveled to City of the Renaissance. A phot (ph) is a photometric unit of illuminance, or luminous flux through an area. 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.

Metric equivalence:

$1\mathrm{p}\mathrm{h}\mathrm{o}\mathrm{t}=1\frac{\mathrm{l}\mathrm{u}\mathrm{m}\mathrm{e}\mathrm{n}}{{\mathrm{c}\mathrm{e}\mathrm{n}\mathrm{t}\mathrm{i}\mathrm{m}\mathrm{e}\mathrm{t}\mathrm{e}\mathrm{r}}^2}=10,000\frac{\mathrm{l}\mathrm{u}\mathrm{m}\mathrm{e}\mathrm{n}\mathrm{s}}{{\mathrm{m}\mathrm{e}\mathrm{t}\mathrm{e}\mathrm{r}}^2}=10,000\mathrm{l}\mathrm{u}\mathrm{x}=10\mathrm{k}\mathrm{i}\mathrm{l}\mathrm{o}\mathrm{l}\mathrm{u}\mathrm{x}$

Metric dimensions:

illuminance = luminous intensity × solid angle / length²
