What Is This Tool?
This tool converts luminous intensity values specifically from the Carcel unit to the Bougie decimal unit, both of which are historical measurements used primarily during the 19th and early 20th centuries. It assists in interpreting and comparing archival photometric data between different historical standards.
How to Use This Tool?
- Enter the luminous intensity value in Carcel units.
- Select the source unit as Carcel unit and the target unit as Bougie decimal.
- Click the convert button to see the equivalent value in Bougie decimal.
- Use the results to interpret or compare historical lighting data accurately.
Key Features
- Converts luminous intensity between Carcel unit and Bougie decimal
- Supports conversion for historical and archival research
- Bridges 19th-century lighting measurement systems
- Browser-based and easy to use without installation
Examples
- 2 Carcel units equal 19.22 Bougie decimals
- 0.5 Carcel unit equals 4.805 Bougie decimals
Common Use Cases
- Analyzing 19th-century oil lamp brightness in historical lighting catalogs
- Interpreting French and European archival photometric documents
- Supporting restoration projects for period lighting equipment
- Studying the development of photometry and measurement units
Tips & Best Practices
- Double-check historical context to ensure appropriate unit usage
- Use conversion results as approximate values due to historical variability
- Apply conversions mainly for educational, archival, or restoration purposes
- Consider the conditions under which original measurements were made
Limitations
- Both Carcel and Bougie decimal units are obsolete and non-standard
- Conversions may vary due to differences in lamp conditions and measurement methods
- Modern photometry relies on the candela, not these historical units
- Precision depends on the original specifications of the oil lamps used
Frequently Asked Questions
- What is a Carcel unit?
- The Carcel unit is a 19th-century historical unit of luminous intensity based on the output from a standardized oil lamp burning colza oil under specific conditions.
- Why convert Carcel to Bougie decimal?
- Converting between these units allows for comparison of historical lighting data from different regions, aiding archival research and understanding of past photometric standards.
- Are these units still used today?
- No, both Carcel and Bougie decimal are obsolete and have been replaced by the candela in modern photometry.
Key Terminology
- Carcel unit
- A historical luminous intensity unit based on the light emitted by a standardized oil lamp using colza oil under defined conditions during the 19th century.
- Bougie decimal
- An obsolete French unit of luminous intensity used in the 19th and early 20th centuries, representing a decimal candle measurement before the adoption of the candela.
- Luminous intensity
- A measure of the wavelength-weighted power emitted by a light source in a particular direction, historically quantified using various units including Carcel and Bougie decimal.
