lux to phot
Please provide values below to convert lux [lx] to phot [ph], or change ↔.
lux [lx]
Definition: A unit of illuminance, measuring the amount of light that falls on a surface area, equal to one lumen per square meter.
Historyandorigin: The lux is part of the International System of Units (SI) and was introduced in the late 19th century as part of the metric system's development.
CurrentUse: It is widely used in lighting design and to measure the intensity of light across a surface in fields such as architecture, photography, and environmental science.
funfact: Lux is commonly used in everyday life to determine how well-lit a room is, with the recommended illuminance level for general reading being about 300 lux.
phot [ph]
Definition: A unit of illuminance that measures the amount of light falling on one square centimeter of a surface, equal to one lumen per square centimeter.
Historyandorigin: The phot was introduced in the early 20th century and was used to measure illuminance, especially in scientific studies.
CurrentUse: It has mostly been replaced by the lux and is no longer widely used, except in some specialized contexts.
funfact: The phot is still occasionally used in older scientific research but has been largely superseded by the SI unit, lux.

How to Convert lux to phot
1 lux [lx] = 0.0001 phot [ph]
1 phot [ph] = 10000 lux [lx]
we use cross multiplication method
lux [lx] → phot [ph]
1 → 0.0001
1.5 → ?( suppose x)
=>1.5*0.0001=1*x
by simplifying
x=0.00015
