lumen/square meter to phot
Please provide values below to convert lumen/square meter [lm/m^2] to phot [ph], or change ↔.
lumen/square meter [lm/m^2]
Definition: A unit of illuminance, representing the amount of luminous flux (in lumens) spread over an area of one square meter.
Historyandorigin: Lumen per square meter is used in photometry to describe how much light falls on a surface.
CurrentUse: It is equivalent to the unit lux and is used worldwide for measuring light intensity in various settings like homes, offices, and street lighting.
funfact: Lumen per square meter (lux) is a standard way to measure lighting levels in buildings and public spaces.
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CurrentUse: It has mostly been replaced by the lux and is no longer widely used, except in some specialized contexts.
funfact: The phot is still occasionally used in older scientific research but has been largely superseded by the SI unit, lux.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 lumen/square meter to phot
1 lumen/square meter [lm/m^2] = 0.0001 phot [ph]
1 phot [ph] = 10000 lumen/square meter [lm/m^2]
we use cross multiplication method
lumen/square meter [lm/m^2] → phot [ph]
1 → 0.0001
1.5 → ?( suppose x)
=>1.5*0.0001=1*x
by simplifying
x=0.00015
