The lux [lx] to foot-candle [ft*c, fc] conversion table and conversion steps are also listed. Lumens, Lux and Candela are often used to describe brightness of light. But what do they really A 60-watt bulb is roughly 800 Lumens. OK, we just covered  (One lumen per square meter equals one lux, and there are 10.8 lux per foot- candle.) Radiometric: watts. This unit is used to deter- mine the energy input and   7 Nov 2016 A requirement of 20 foot candles is recommended for general spaces in offices. as sunny conditions provide illumination up to 10,000 lux).

The international standard (SI) counterpart of the foot-candle is the "lux." A lux equals 1 lumen per square meter. The equation used to convert foot-candles to lux is: 1 foot-candle = 10.76 lux.

Measure - Micronix

It works this way: 1000 lux (100fc) doubles to 2000 lux (200fc). That is one stop brighter. Double 2000 lux (200fc) to 4000 lux (400fc) and the brightness increases by another stop for a total of 2 stops more light. So … At 4000 lux (400fc) the exposure is two stops more light and is controlled by stopping down by 2 f/stops. One foot candle is about 10.764 lux. Since one foot-candle is the illuminance cast on a surface by a one-candela source one foot away, a lux could be thought of as a "metre-candle", although this term is discouraged because it does not conform to SI standards for unit names.

The power P in watts (W) is equal to the 0.09290304 times the illuminance E v in lux (lx) times the surface area A in square feet (ft 2), divided by the luminous efficacy η in lumens per watt (lm/W): P (W) = 0.09290304 × E v(lx) × A (ft 2) / η (lm/W) Lux to watts calculation with area in A foot candle is equal to about 10 lux. Lux measures luminous intensity just like a lumen, but is in the International System of Units (SI), which is the modern form of the metric system.
