watt/sq. cm (at 555 nm) to foot-candle
Please provide values below to convert watt/sq. cm (at 555 nm) to foot-candle [ft*c, fc], 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.
foot-candle [ft*c, fc]
Definition: A unit of illuminance, equal to one lumen per square foot.
Historyandorigin: The foot-candle was used primarily in the United States and is based on the imperial system of measurement.
CurrentUse: It is still used in some areas, especially in the U.S. for lighting design and environmental assessments.
funfact: One foot-candle is approximately 10.764 lux, making it a convenient unit for those still using imperial units.

How to Convert watt/sq. cm (at 555 nm) to foot-candle
1 watt/sq. cm (at 555 nm) = 634527.7632 foot-candle [ft*c, fc]
1 foot-candle [ft*c, fc] = 0.000001576 watt/sq. cm (at 555 nm)
we use cross multiplication method
watt/sq. cm (at 555 nm) → foot-candle [ft*c, fc]
1 → 634527.7632
1.5 → ?( suppose x)
=>1.5*634527.7632=1*x
by simplifying
x=951791.6448
