watt/sq. cm (at 555 nm) to lumen/square foot
Please provide values below to convert watt/sq. cm (at 555 nm) to lumen/square foot [lm/ft^2], or change ↔.
watt/sq. cm (at 555 nm)
Definition: A unit of radiometric power, measuring the amount of radiant power (in watts) per square centimeter at a wavelength of 555 nm, which corresponds to the peak sensitivity of the human eye.
Historyandorigin: This unit is used in photometry to understand the power of light sources that emit light at wavelengths that the human eye is most sensitive to.
CurrentUse: It is used in scientific applications where precise measurement of light intensity at 555 nm is required, such as in the study of vision and optical systems.
funfact: The 555 nm wavelength is in the green part of the spectrum and is the most efficient wavelength for human vision, which is why this unit is used to measure visual brightness.
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 watt/sq. cm (at 555 nm) to lumen/square foot
1 watt/sq. cm (at 555 nm) = 634527.7632 lumen/square foot [lm/ft^2]
1 lumen/square foot [lm/ft^2] = 0.000001576 watt/sq. cm (at 555 nm)
we use cross multiplication method
watt/sq. cm (at 555 nm) → lumen/square foot [lm/ft^2]
1 → 634527.7632
1.5 → ?( suppose x)
=>1.5*634527.7632=1*x
by simplifying
x=951791.6448
