FAQs
What is illuminance?
Illuminance measures how much light falls on a surface and is typically measured in lux (lumens per square meter).
Can I convert lux to lumen?
Lux already includes lumens per area. This tool converts between lux and equivalents like lumens per square centimeter or foot-candles.
Is this suitable for photography or cinematography?
Yes. The tool supports units like foot-candles, used widely in film and lighting setups.
Does it support SI and non-SI units?
Yes. It supports SI units like lux and kilolux, as well as non-SI units like foot-candle and nox.
Do I need to install anything?
No. This is a web-based tool that runs in your browser—no download needed.
Will my data be saved or uploaded?
No. The tool works entirely offline and we do not save or transmit user data.
Is the tool free?
Yes. It’s completely free to use, with no ads or registration.
Can it handle very high or small values?
Yes. It supports scientific notation for extreme illuminance levels.
