Luminous Flux Converters
Pick a family to convert between common luminous flux units used in lighting specifications.
Explanation
Luminous flux measures total visible light output and is expressed in lumens (lm). This hub applies exact SI prefix scaling across lumens, kilolumens, and megalumens for direct mirror conversion paths.
How to use this hub
- Choose a converter family.
- If converting to/from grams from a volume unit, select an ingredient.
- For pure unit changes (volume↔volume or weight↔weight), use universal conversions.
If your conversion includes grams, you’ll choose an ingredient; otherwise you won’t.
