SwitchExplanation
Formula: Foot-candles = Phot × 929.0304. Why: phot is tied exactly to lux through the square-centimeter to square-meter area relationship, so the route normalizes through lux before applying the target unit.
Phot (ph): a CGS illuminance unit equal to one lumen per square centimeter, which is exactly 10,000 lux.
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.
