When the metric area over which luminous flux is spread is taken into account, the SI measurement of illuminance, or lux (lx), is used. Alternately, when non-metric (foot) area is calculated, the non-SI footcandle (fc) unit is used to measure illuminance. Mathematically, one lux equals one lumen per square meter, or 1 lx= 1 lm/m2. Conversely, one footcandle equals one lumen per square foot, or 1 fc = 1 lm/ft2. Finally, one footcandle is approximately equal to 10.764 lux.
