What Is This Tool?
This unit converter transforms values from the informal 'flame' unit, representing light from open combustion sources, into the phot [ph] unit, a standardized older measure of illuminance. It helps convert qualitative lighting descriptions into quantifiable photometric values.
How to Use This Tool?
- Enter the number of flames as the source illumination value
- Choose 'flame' as the input unit and 'phot [ph]' as the target unit
- Click convert to obtain the corresponding phot value using the formula
- Review the result displayed in phot [ph] for your reference or calculations
Key Features
- Converts informal 'flame' illumination values to the standardized phot [ph] unit
- Uses the precise formula: 1 Flame = 0.0043055642 Phot [ph]
- Supports applications in lighting engineering, safety operations, and historical lighting analysis
- Browser-based and easy to use with clear step-by-step conversion
- Facilitates comparison between descriptive and scientific light measurements
Examples
- 5 Flames = 5 × 0.0043055642 = 0.02153 Phot [ph]
- 10 Flames = 10 × 0.0043055642 = 0.04306 Phot [ph]
Common Use Cases
- Translating informal or qualitative light levels from open flames into standardized illumination units
- Supporting lighting design and engineering with quantifiable photometric values
- Historical research involving lighting conditions described in older technical documents or literature
- Safety, firefighting, and fieldwork where approximate light levels from flames inform operations
- Anthropology and archaeology contexts requiring rough estimates of natural illumination levels
Tips & Best Practices
- Use this conversion to move from qualitative to quantitative light measurements for clarity
- Apply with caution, considering flame intensity and environment variability affecting accuracy
- Remember phot [ph] is an older unit largely replaced by lux; adapt results accordingly
- Use for rough estimates rather than precise illuminance in scientific or engineering contexts
Limitations
- 'Flame' is a non-standard, informal unit lacking exact definition; conversions are approximate
- Phot is a historical unit; most modern standards use lux for illuminance measurements
- Flame intensity varies by source and conditions, making precise conversion challenging
- Results should be treated as rough estimates rather than exact figures
Frequently Asked Questions
- What does the unit 'flame' represent?
- 'Flame' is an informal term describing light emitted by open combustion sources, such as candles or torches. It is not standardized in photometry.
- What is a phot [ph] unit used for?
- The phot [ph] is an older unit of illuminance equal to one lumen per square centimetre, used historically for high-level lighting measurements.
- Is the flame to phot conversion exact?
- No, since 'flame' is informal and variable, conversions provide approximate estimates rather than precise values.
Key Terminology
- Flame
- An informal, non-standard unit describing illumination from an open combustion light source.
- Phot [ph]
- An older unit of illuminance equal to one lumen per square centimetre, equivalent to 10,000 lux.
- Illuminance
- The measure of luminous flux incident on a surface, usually expressed in lux or phot.
