Why this tool is useful
Use this converter when specifications, downloads or measurements are given in foot-candles, but your worksheet or destination requires kilolux. It avoids manual factor mistakes.

Convert foot-candles (fc) to kilolux (klx) with a transparent illuminance formula.
Ready. Your working data stays in this browser.
Use this converter when specifications, downloads or measurements are given in foot-candles, but your worksheet or destination requires kilolux. It avoids manual factor mistakes.
The browser converts fc to the shared illuminance base unit using scale 10.7639 and offset 0, then converts that base value to klx using scale 1000 and offset 0.
For example, entering 1 fc returns 0.01076391042 klx. Results include the formula and enough precision for a quick verification.
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
