Illumination Converter
Light falling on a surface: lux, foot-candles, phots and lumens per area. A bulb’s total lumens (luminous flux) is a different quantity.
That is below absolute zero (−273.15 °C), which isn’t physically possible.
1 Lux = 0.09290304 Foot-candles
Formula: multiply the illumination value by 0.09290304

How to convert illumination units
Light falling on a surface: lux, foot-candles, phots and lumens per area. A bulb’s total lumens (luminous flux) is a different quantity. Every conversion goes through one base unit, the lux, using exact factors, so results don’t drift.
Lux to foot-candles (lx to fc)
To convert lux to foot-candles, multiply by 0.09290304. 1 lux = 0.09290304 foot-candles.
| lx | fc |
|---|---|
| 1 lx | 0.09290304 fc |
| 2 lx | 0.1858061 fc |
| 5 lx | 0.4645152 fc |
| 10 lx | 0.9290304 fc |
| 20 lx | 1.858061 fc |
| 50 lx | 4.645152 fc |
| 100 lx | 9.290304 fc |
Foot-candles to lux (fc to lx)
To convert foot-candles to lux, divide by 0.09290304. 1 foot-candle = 10.76391 lux.
| fc | lx |
|---|---|
| 1 fc | 10.76391 lx |
| 2 fc | 21.52782 lx |
| 5 fc | 53.81955 lx |
| 10 fc | 107.6391 lx |
| 20 fc | 215.2782 lx |
| 50 fc | 538.1955 lx |
| 100 fc | 1,076.391 lx |
Kilolux to lux (klx to lx)
To convert kilolux to lux, multiply by 1,000. 1 kilolux = 1,000 lux.
Phots to lux (ph to lx)
To convert phots to lux, multiply by 10,000. 1 phot = 10,000 lux.
