What is the equivalent unit to a foot-candle?

A foot-candle equals one lumen per square foot. This is a British measurement. Using the metric system, a lumen is measured by a square meter or a lux. Thus a foot-candle is equivalent to approximately 10 lux or 10.57 lux.

How do you convert foot candles to lumens?

One foot-candle equals 10.76 lumens (a lumen is considered the same as lux, which is what most modern light meters calculate their measurements in), so in order to convert your foot-candles to lumens, you will need to take the amount of foot-candles measured and multiply by 10.76 to get the number of lumens.

How do you convert EV to lux?

1 Answer

  1. EV is 5 Lux.
  2. EV is 10 Lux.
  3. EV is 20 Lux.

How do I calculate foot candles?

Multiply the Length times the Width of the Room to get the Room Square Footage. For example, if the room is 10 feet wide and 10 feet long, the Room Square Footage will be 100 square feet. A foot-candle is how bright the light is one foot away from the source.

What is the difference between lux and footcandles?

Foot-candles and lux measure the same thing—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.).

Is lux and EV the same?

From the chart you link to, that looks really easy: 0 EV is 2.5 Lux, and each +1 EV doubles Lux.

What is the difference between lux and EV?

Exposure Value (EV) to Lux Converter Valid for ISO=100, C=250. The EV range is -4 to 16. The lux range is 0.156 to 16,384.

What is CCT K?

CCT is defined in degrees Kelvin; a warm light is around 2700K, moving to neutral white at around 4000K, and to cool white, at 5000K or more. Note that CCT does not tell you anything about the color rendering ability of the LED.

What is the formula for converting Lux to footcandles?

Formula of converting lux to footcandles. Ev (fc) = Ev (lx) x 0.09290304 = Ev (lx) / 10.76391. It means that the illuminance in footcandles is calculated by multiplying 0.09290304 by the illuminance in lux.

How do you calculate the illuminance of a foot candle?

Formula of converting lux to footcandles Ev (fc) = Ev (lx) x 0.09290304 = Ev (lx) / 10.76391. It means that the illuminance in footcandles is calculated by multiplying 0.09290304 by the illuminance in lux. The illuminance in footcandles can also be calculated by dividing the illuminance in lux by 10.76391.
