Lux to Footcandles
Lux :
  • Light or visible light is electromagnetic radiation that can be perceived by the human eye.
  • Visible light is usually defined as having wavelengths in the range of 400–700 nanometres, corresponding to frequencies of 750–420 terahertz, between the infrared and the ultraviolet.
  • Then, the symbol of lux is lx.
Footcandles :
  • A foot-candle is a non-SI unit of illuminance or light intensity. Then, it is defined as one lumen per square foot.
  • Then, the symbol of footcandles is fc.
Lux to Footcandles :
  • One foot-candle is equal to approximately 10.76 lux.
  • In many practical applications, as when measuring room illumination. 
  • It is often not needed to measure illuminance more accurately than ±10%.
  • Then, these situations it is sufficient to think of one foot-candle as about ten lux.
  • Foot-candles and lux measure the same thing and then the amount of visible light that falls on a surface.
  • The difference is that the foot-candle uses the Imperial standard measuring system (feet, pounds, etc.), while the lux uses the metric system (meters, grams, etc.).
Formula :
  • The formula used to calculate the following calculator lux to footcandles is given below.
  • So, the calculation formula = Illuminance in Lux * 0.09290304.
  • Besides the formula this calculator works.
How to Calculate ?
  • First, Enter illuminance in lux.
  • Click “Calculate” to get the result and then if you want to clear values Click “Reset” in addition to clear the values.
  • Finally, follow these steps to get the results.
  • Then you will get as a illuminance result in footcandles.
