What Is This Tool?
This converter transforms luminous intensity measurements expressed in the carcel unit, an old 19th-century standard based on a specific oil lamp, into hefner candle values, a former German unit defined by a specialized lamp burning amyl acetate.
How to Use This Tool?
- Enter the value in carcel unit you wish to convert.
- Select 'carcel unit' as the source unit and 'hefner candle' as the target unit.
- Click the convert button to see the equivalent value in hefner candles.
- Use the result for research, documentation, or historical lighting analysis.
Key Features
- Converts between two historical luminous intensity units: carcel unit and hefner candle.
- Browser-based and user-friendly interface for quick and simple conversions.
- Supports interpretation of antique lighting specifications and archival data.
- Facilitates restoration and calibration of vintage photometric instruments.
Examples
- 2 Carcel units equals 21.3555555602 Hefner candles.
- 0.5 Carcel unit converts to 5.33888889005 Hefner candles.
Common Use Cases
- Comparing brightness values of 19th-century oil lamps in historical lighting catalogs.
- Interpreting and converting antique photometric data from German-speaking regions.
- Supporting museum curation and archival record documentation of period illumination.
- Restoring and calibrating vintage photometric instruments referencing obsolete units.
Tips & Best Practices
- Verify the historical context and standardization conditions when interpreting unit values.
- Use this converter primarily for research and archival purposes rather than modern lighting design.
- Cross-reference converted values when documenting or restoring historical lighting artifacts.
Limitations
- Both the carcel unit and hefner candle are outdated and not applicable in current SI measurements.
- Conversion precision may vary due to historical variations in lamp conditions and standards.
- The tool is intended for historical, research, and archival contexts, not for practical lighting engineering.

- The carcel unit is a historical measure of luminous intensity based on a 19th-century oil lamp with specified wick and burner conditions.
- What does the hefner candle represent?
- The hefner candle is an obsolete luminous intensity unit defined by a standardized lamp burning amyl acetate, formerly used in German-speaking countries.
- Why convert between carcel unit and hefner candle?
- Converting between these units helps researchers and archivists interpret historical lighting data and calibrate vintage instruments from different regional standards.
Key Terminology
- Carcel unit
- A 19th-century luminous intensity unit based on the light emitted by a standardized oil lamp burning colza oil under specified conditions.
- Hefner candle
- An obsolete luminous intensity unit defined by a lamp burning amyl acetate, historically used in German-speaking areas before the candela.
