About This Tool
This tool converts illumination values from foot-candle (fc) to lux (lx) with a simple, math-driven approach. It serves professionals in lighting design, electrical engineering, facility management, and academic settings who work with both imperial and metric units.
Conceptually, the conversion uses the exact factor 1 fc = 10.764 lux. Users provide a value in fc and receive an immediate lux result. The system validates input, applies the factor, and formats the output to two decimal places.
Unique value includes precise constant, immediate feedback, and robust validation for non-numeric or negative inputs. It supports quick cross-unit data integration in reports and spreadsheets, without requiring external tools.
Typical use cases include lighting design reviews, compliance checks, energy calculations, and educational demonstrations. The tool is suitable for engineers, designers, students, and facility teams seeking SI-consistent results.
How to Use
1. Provide the fc value in foot-candle units (e.g., 50 fc).
2. The tool computes the equivalent lux value instantly using the standard factor (1 fc = 10.764 lux).
3. Read the lux result (formatted to two decimals).
4. Use the output in lighting calculations or documentation.
5. Copy or export the value if needed.
