phot to lumen/square foot
Please provide values below to convert phot [ph] to lumen/square foot [lm/ft^2], or change ↔.
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CurrentUse: It has mostly been replaced by the lux and is no longer widely used, except in some specialized contexts.
funfact: The phot is still occasionally used in older scientific research but has been largely superseded by the SI unit, lux.
lumen/square foot [lm/ft^2]
Definition: A unit of illuminance, measuring the amount of luminous flux (in lumens) distributed over one square foot of surface area.
Historyandorigin: It is part of the imperial measurement system and was used in the United States before the metric system became more widely adopted.
CurrentUse: It is still used in some industries in the U.S. and is roughly equivalent to 10.764 lux.
funfact: The lumen per square foot is useful for understanding light levels in spaces like offices and schools where the imperial system is still in use.

How to Convert phot to lumen/square foot
1 phot [ph] = 929.0304 lumen/square foot [lm/ft^2]
1 lumen/square foot [lm/ft^2] = 0.001076391 phot [ph]
we use cross multiplication method
phot [ph] → lumen/square foot [lm/ft^2]
1 → 929.0304
1.5 → ?( suppose x)
=>1.5*929.0304=1*x
by simplifying
x=1393.5456
