flame to lumen/square foot
Please provide values below to convert flame to lumen/square foot [lm/ft^2], or change ↔.
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CurrentUse: It is no longer used in modern lighting systems and has been replaced by more accurate and standardized units.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.
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 flame to lumen/square foot
1 flame = 4 lumen/square foot [lm/ft^2]
1 lumen/square foot [lm/ft^2] = 0.25 flame
we use cross multiplication method
flame → lumen/square foot [lm/ft^2]
1 → 4
1.5 → ?( suppose x)
=>1.5*4=1*x
by simplifying
x=6
