Illuminance conversion is essential in many fields:
Lighting Design
Architects and lighting designers use illuminance measurements to ensure proper lighting levels in buildings, offices, and public spaces according to safety standards.
Photography & Cinematography
Photographers and videographers use light meters that often display values in different units. Converting between lux and foot-candles helps achieve proper exposure.
Plant Cultivation
Indoor farming and greenhouse operations require specific light levels for optimal plant growth, often measured in lux or foot-candles.
Workplace Safety
Occupational health regulations specify minimum illuminance levels for workplaces to prevent eye strain and ensure safety.
Display Manufacturing
Screen brightness specifications often require conversion between different illuminance units for international markets.
Scientific Research
Researchers studying photobiology, circadian rhythms, or solar radiation need to convert between various illuminance units.
