What Is This Tool?

This converter helps you transform luminous intensity measurements from the Carcel unit, a 19th-century standard based on a colza oil lamp, into the Candle (pentane) unit, an earlier photometric measure derived from a pentane-fueled flame. It supports historical research and comparison of early lighting standards.

Frequently Asked Questions

What is the Carcel unit?
The Carcel unit is a historical measure of luminous intensity based on a standardized oil lamp burning colza oil, used primarily in the 19th century for early photometry.

How is the Candle (pentane) unit defined?
Candle (pentane) is an old non-SI luminous intensity unit defined by the light from a pentane-fueled flame, used historically before the adoption of the candela.

Why should I convert Carcel units to Candle (pentane)?
Converting helps interpret and compare early photometric data, which is valuable for historical research, museum conservation, and educational purposes.

Key Terminology

Carcel unit
A 19th-century luminous intensity unit based on the light from a standardized oil lamp burning colza oil under specified conditions.
Candle (pentane)
A historical non-SI unit of luminous intensity based on the light from a pentane-fueled flame, used in early photometry before the candela.
Luminous intensity
A measure of the wavelength-weighted power emitted by a light source in a particular direction, perceived by the human eye.
