SwitchExplanation
Formula: Foot-candles = Lux × 0.092903. Why: this is a cross-system illuminance conversion. The calculator normalizes the value through lux, then applies the exact target-unit constant for consistent lighting and exposure work.
Lux (lx): the SI derived unit of illuminance, equal to one lumen incident on one square meter of surface area.
Foot-candles (fc): an imperial illuminance unit based on lumens per square foot, common in lighting design, building standards, and photographic exposure references.
This route is useful when translating illuminance values between lux-based and foot-candle scales for architectural lighting, workplace standards, and exposure measurements.
This conversion is purely multiplicative because both units reduce through lux using fixed illuminance definitions with no offset.
