What Is This Tool?
This converter helps transform values between two historical units of luminous intensity: the candle (international) and the hefner candle. Both units are obsolete and were used before the adoption of the modern candela. The tool facilitates interpretation and comparison of old photometric data and lighting standards.
How to Use This Tool?
- Enter the luminous intensity value in candle (international)
- Select the target unit as hefner candle
- Click convert to see the equivalent value
- Use the conversion result for historical comparison or technical interpretation
Key Features
- Converts luminous intensity from candle (international) to hefner candle
- Based on historical standard lamps and obsolete units
- Supports research, restoration, and archival work
- Browser-based and easy to use
Examples
- 5 candle (international) equals 5 × 1.111111111 = 5.555555555 hefner candle
- 10 candle (international) equals 10 × 1.111111111 = 11.11111111 hefner candle
Common Use Cases
- Specifying luminous intensity in older standards and datasheets
- Analyzing lighting data from historical research documents
- Converting photometric measurements for restoration of antique instruments
- Interpreting period lighting specifications from German-speaking regions
Tips & Best Practices
- Use this conversion primarily for interpreting historical and legacy lighting data
- Understand that both units are no longer used in modern measurements
- Check original context for accurate application of conversion
- Combine with other unit conversions when restoring or calibrating old instruments
Limitations
- Units are obsolete and not suitable for modern photometric applications
- Conversion precision is limited by original lamp standardization conditions
- Intended mainly for historical research and archival interpretation
Frequently Asked Questions
- Why are candle (international) and hefner candle no longer used?
- Both units are obsolete and have been replaced by the candela in the International System of Units for standardizing luminous intensity.
- Can this conversion be used for modern lighting design?
- No, this conversion is intended mainly for historical research, restoration, and interpretation of older photometric data.
- What is the conversion factor between candle (international) and hefner candle?
- 1 candle (international) equals 1.111111111 hefner candle.
Key Terminology
- Candle (international)
- An obsolete photometric unit representing luminous intensity based on a historic standard lamp used before the candela.
- Hefner candle
- An obsolete luminous intensity unit defined by a standardized lamp burning amyl acetate; used historically mainly in German-speaking countries.
- Luminous intensity
- A measure of the wavelength-weighted power emitted by a light source in a particular direction.
