gigalumen to decilumen
Convert gigalumen (Glm) to decilumen (dlm). Use an editable luminous flux converter, conversion formula, and reference table.
1 Glm = 10,000,000,000 dlm
Conversion formula
One gigalumen equals 10,000,000,000 decilumen. Multiply your value in gigalumen by this factor to get decilumen. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 gigalumen:5 × 10,000,000,000 = 50,000,000,000 dlm

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 decilumen is 0.1 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 dlm?
