About these measurements
Illuminance is luminous flux falling on a surface per unit area.
The base reference used here is the lux. One gigalux is 1,000,000,000 base units; one foot-candle is 10.76391042 base units.
Important distinctions
One lux is one lumen per square meter.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
