What Is This Tool?
This tool allows you to convert illumination measurements from foot-candle, a standard lighting unit, to flame, an informal and qualitative descriptor of light emitted by an open combustion source. It is designed for non-technical purposes where approximate visual comparisons are sufficient.
How to Use This Tool?
- Enter the illumination value in foot-candles into the input field.
- Select 'foot-candle' as the starting unit and 'flame' as the target unit.
- Press the convert button to get the equivalent light level in flames.
- Use the result for informal descriptions or rough light level comparisons.
Key Features
- Quickly convert from foot-candle (lumen per square foot) to flame, an informal unit of light.
- Useful for translating precise lighting data into relatable, observational descriptions.
- Browser-based and easy to use without requiring specialized knowledge.
- Supports qualitative lighting assessments in various fields such as restoration, safety, and anthropology.
Examples
- 4 Foot-candles convert to 1 Flame.
- 8 Foot-candles convert to 2 Flames.
Common Use Cases
- Specifying lighting levels in offices, retail spaces, and buildings using foot-candles, then describing them informally in terms of flames.
- Informal or historical lighting descriptions in restoration, conservation, and literature.
- Safety and firefighting contexts where the presence of flames indicates relative illumination.
- Fieldwork in archaeology or anthropology where precise measurements are impractical.
Tips & Best Practices
- Use the flame unit only for qualitative, non-technical descriptions of light intensity.
- Avoid using flame for professional lighting design or engineering calculations.
- Consider environmental factors that can affect the perceived brightness of a flame.
- Use foot-candle measures for precise and standardized illumination requirements.
Limitations
- Flame is not a standardized or scientifically exact unit of illumination.
- The size, fuel type, and environment affect the brightness of a flame, causing variations.
- Conversion is approximate and best applied for illustrative or qualitative purposes.
- Not suitable for rigorous photometric or engineering applications.
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.
- Why use flame as a unit of illumination?
- Flame serves as an informal and qualitative way to describe light intensity when exact measurements are not needed or practical.
- Can I use this conversion for precise lighting design?
- No, the flame unit is approximate and not standardized, so it is unsuitable for professional lighting or engineering calculations.
Key Terminology
- Foot-candle [ft*c, fc]
- A non‑SI unit of illuminance equal to one lumen per square foot, used mainly in North American lighting practice.
- Flame
- An informal, non-standardized description of light from an open combustion source, used for qualitative descriptions.
- Illuminance
- The luminous flux incident on a surface, generally measured in units like foot-candle or lux.
