Please provide values below to convert lumen/square foot [lm/ft^2] to flame, or change ↔.
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.
flame
Definition: An older, informal unit of light intensity, typically referring to the brightness produced by a flame, often used for measuring gas lamp light output.
Historyandorigin: The flame unit was used in the 19th and early 20th centuries when gas lamps were a major source of light.
CurrentUse: It is no longer used in modern lighting systems and has been replaced by more accurate and standardized units.
funfact: The flame unit was part of the early photometric measurements of light intensity, particularly for gas lamps.

How to Convert lumen/square foot to flame
1 lumen/square foot [lm/ft^2] = 0.25 flame
1 flame = 4 lumen/square foot [lm/ft^2]
we use cross multiplication method
lumen/square foot [lm/ft^2] → flame
1 → 0.25
1.5 → ?( suppose x)
=>1.5*0.25=1*x
by simplifying
x=0.375
