About this tool
Convert lux to foot-candles instantly. Free, bidirectional, and fully in-browser.
1 lux equals 0.09290304 foot-candles — enter any lux value to convert it to foot-candles instantly. This Lux to Foot-candle converter is a client-side tool: it applies a single multiplication (fc = lx × 0.09290304) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert foot-candles back to lux. A reference table lists common lux values already converted, and nothing you enter is sent to a server.
Open Lux to Foot-candle Converter on AltFTool — it loads instantly in your browser.
Type the value you want to convert into the Lux field.
Read the equivalent in foot-candles in the result field, and copy it if needed.
Use the decimal-places slider for more or less precision, or press swap to convert foot-candles to lux.
The result updates as you type, and the swap button flips the conversion to foot-candle → lux without reloading.
The conversion uses the precise factor (fc = lx × 0.09290304), so the number matches a manual calculation to the decimal places you choose.
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Everything runs locally in your browser — no upload, no account, no limit on conversions.
