Illuminance Converter
Convert illuminance units like lux and foot-candles for lighting and photography.
About Illuminance Converter
Photographers, growers and architects need to translate lux, foot-candles and lumens per square metre. Tooloria’s Illuminance Converter does exactly that, including photometric conversions from lumens and area. A “camera mode” shows EV values for exposure planning, while horticulture mode indicates PPFD guidelines. All computations remain client-side.
Frequently Asked Questions
Lux versus lumens—what’s the difference?
Lumens measure light output; lux measures illumination on a surface (lumens per square metre). The converter handles both when you supply area.
How does camera mode work?
Enter desired EV and ISO, and the tool translates lux to shutter-speed and aperture suggestions—handy for manual shooting.
Does it support PPFD for plants?
Yes—enable horticulture mode to convert lux readings to approximate photosynthetic photon flux density in μmol·m⁻²·s⁻¹.
