How to Use This Tool?
- Enter the value in pentane candle (10 candle power) you wish to convert.
- Select carcel unit as the target measurement.
- Click convert to obtain the corresponding luminous intensity in carcel units.
Key Features
- Converts values between pentane candle (10 candle power) and carcel unit.
- Based on historical luminous intensity standards from candle and oil lamp measurements.
- Suitable for interpreting and comparing 19th-century lighting data.
- Browser-based and easy to use for researchers and historians.
Examples
- 5 pentane candles (10 candle power) equals approximately 5.2029 carcel units.
- 2 pentane candles (10 candle power) equals approximately 2.0812 carcel units.
Common Use Cases
- Comparing light output of candles and lamps in historical lighting literature.
- Translating photometric measurements recorded with candle-based units.
- Documenting and analyzing 19th-century lighting standards in museum or academic settings.
- Restoring and studying antique lamps using historical luminous intensity data.
Tips & Best Practices
- Use this tool primarily for historical or academic research rather than modern lighting design.
- Cross-check converted values when interpreting old lighting specifications.
- Understand that both units are based on outdated measurement standards.
- Apply the conversion in the context of 19th-century lighting calibration and documentation.
Limitations

- Conversion values may carry uncertainties due to historical variations in lamp conditions.
- Not intended for modern engineering or practical lighting applications.
Frequently Asked Questions
- What is a pentane candle (10 candle power)?
- It is a historical unit of luminous intensity based on a standard candle burning pentane, representing ten times the traditional candle unit.
- What does the carcel unit measure?
- The carcel unit is a historical luminous intensity measure defined by the light output of a standardized oil lamp burning rapeseed oil under specific conditions.
- Why convert between pentane candle (10 candle power) and carcel units?
- This helps translate and compare 19th-century lighting measurements recorded with different candle-based standards in research and historical documentation.
Key Terminology
- Pentane candle (10 candle power)
