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.
