What Is This Tool?
This converter transforms values measured in carcel units, an outdated 19th-century luminous intensity unit based on a standardized oil lamp, into candle (international) [c], another historical unit formerly used for photometric reference before modern units like the candela.
How to Use This Tool?
- Enter the value measured in carcel units into the input field
- Select 'carcel unit' as the source unit and 'candle (international) [c]' as the target unit
- Click the convert button to see the equivalent luminous intensity in candle (international) [c]
- Use the result for interpreting historical luminous intensity data or converting old photometric standards
Key Features
- Converts between two obsolete luminous intensity units used historically in lighting studies
- User-friendly interface ideal for historical lighting research and archival documentation
- Supports interpretation and comparison of legacy photometric measurements
- Browser-based tool requiring no installation or special hardware
- Facilitates understanding of older lighting standards and technical documents
Examples
- 1 Carcel unit equals 9.61 Candle (international) [c]
- 5 Carcel units convert to 48.05 Candle (international) [c]
Common Use Cases
- Translating historical illumination data from 19th-century sources
- Analyzing legacy lighting specifications and photometric experiments
- Supporting museum or archival descriptions involving old luminous intensity units
- Converting obsolete measurement units for engineering analysis of early lighting technologies
- Comparing luminous intensity standards before adoption of the modern candela
Tips & Best Practices
- Use this conversion primarily for historical or archival research rather than modern scientific work
- Be mindful that both units are non-SI and have variable definitions tied to specific lamp conditions
- Verify the context of old data before applying conversions to ensure appropriate interpretation
- Consider consulting original measurement conditions when analyzing conversion results
- Use modern SI units such as candela for precise photometric calculations wherever possible
Limitations
- Both carcel unit and candle (international) [c] are obsolete and non-SI units
- Definitions rely on specific historical lamp types and conditions that may vary
- Conversion accuracy is limited by variations in the original lamp standards
- Not suitable for precise modern engineering or scientific photometric calculations
- Historical context may affect how conversions should be interpreted or applied
Frequently Asked Questions
- What is a carcel unit?
- A carcel unit is a historical measure of luminous intensity based on a standardized 19th-century oil lamp using colza (rapeseed) oil with defined wick and burner conditions.
- How does candle (international) [c] differ from modern candela?
- Candle (international) [c] is an outdated photometric unit defined by a standard lamp used before the SI candela was adopted; it appears mainly in older technical literature.
- Why convert between carcel unit and candle (international) [c]?
- Converting helps interpret and compare historical luminous intensity data measured with different legacy standards for research or archival purposes.
Key Terminology
- Carcel unit
- A 19th-century luminous intensity measure based on the light from a standardized oil lamp burning colza oil under specified conditions.
- Candle (international) [c]
- An outdated photometric unit defined by the intensity of a standard lamp, used historically before modern SI definitions like the candela.
- Luminous intensity
- A photometric measure of the wavelength-weighted power emitted by a light source in a particular direction.
