What Is This Tool?
This converter transforms illumination values from foot-candles, a North American non-SI unit measuring luminous flux per square foot, to lux, the SI unit measuring luminous flux per square meter. It helps users apply consistent lighting standards across various applications.
How to Use This Tool?
- Enter the illumination value in foot-candle (ft*c, fc).
- Select foot-candle as the source unit and lux (lx) as the target unit.
- Click the convert button to get the equivalent illuminance in lux.
- Review conversion results and examples to confirm accuracy.
- Use the output for applications like lighting design or photographic exposure settings.
Key Features
- Converts foot-candle (ft*c, fc) values accurately to lux (lx).
- Supports lighting design, photography, horticulture, and compliance purposes.
- Provides clear unit definitions and context for practical use.
- Web-based and easy to use with no installation required.
- Displays conversion examples for quick verification.
Examples
- 5 foot-candles equals 53.8195520835 lux based on the conversion rate.
- 10 foot-candles converts to 107.639104167 lux using the given formula.
Common Use Cases
- Specifying and verifying task lighting in offices and retail environments.
- Setting exposure levels in photography, film production, and stage lighting.
- Managing recommended light intensities in museums, galleries, and greenhouses.
- Aligning North American lighting specifications with international lux standards.
- Supporting compliance with building codes and lighting design criteria.
Tips & Best Practices
- Always verify the converted lux values with application requirements.
- Consider environmental conditions that may affect illuminance readings.
- Use this tool to maintain consistency when working with both foot-candle and lux units.
- Apply the conversion carefully in critical lighting applications to avoid errors.
- Refer to provided examples to understand and validate conversions.
Limitations
- Foot-candle is a non-SI unit mainly used in North America, requiring precise conversion.
- Environmental and measurement factors may impact illuminance values beyond unit conversion.
- Conversion accuracy depends on exact use of the provided rate; avoid assumptions.
Frequently Asked Questions
- What is a foot-candle?
- A foot-candle is a non-SI unit of illuminance equal to one lumen per square foot, commonly used in North American lighting practices.
- How is lux defined?
- Lux is the SI derived unit of illuminance defined as one lumen per square meter, weighted by the human photopic visual response.
- Why convert foot-candle to lux?
- Converting foot-candle to lux helps standardize illumination measures for international lighting design, photography, and horticulture requirements.
Key Terminology
- Foot-candle
- A non-SI unit of illuminance equal to one lumen per square foot, used mainly in North America.
