Phots to Foot-Candles Converter
Convert phots (ph) to foot-candles (fc) with a transparent illuminance formula.
Ready. Your working data stays in this browser.
How it works
The browser converts ph to the shared illuminance base unit using scale 10000 and offset 0, then converts that base value to fc using scale 10.7639 and offset 0.
Practical example
For example, entering 1 ph returns 929.0304 fc. Results include the formula and enough precision for a quick verification.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
