gigalux to lux
Convert gigalux (Glx) to lux (lx). Use an editable illuminance converter, conversion formula, and reference table.
1 Glx = 1,000,000,000 lx
Conversion formula
One gigalux equals 1,000,000,000 lux. Multiply your value in gigalux by this factor to get lux. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 gigalux:5 × 1,000,000,000 = 5,000,000,000 lx

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 lux is 1 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.
