gigalumen to kilolumen
Convert gigalumen (Glm) to kilolumen (klm). Use an editable luminous flux converter, conversion formula, and reference table.
1 Glm = 1,000,000 klm
Conversion formula
One gigalumen equals 1,000,000 kilolumen. Multiply your value in gigalumen by this factor to get kilolumen. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 gigalumen:5 × 1,000,000 = 5,000,000 klm

About these measurements
Luminous flux measures the visible-light output weighted by human visual sensitivity.
The base reference used here is the lumen. One gigalumen is 1,000,000,000 base units; one kilolumen is 1,000 base units.
Important distinctions
Lumens measure light output; lux measures illumination per unit area.
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.
Common questions
How do I convert Glm to klm?
