FOOTCANDLE Meaning and
Definition
-
A footcandle is a unit of measurement used to quantify the intensity of light received at a specific point at a given distance from a light source. It is defined as the amount of light illuminating a one square foot surface from a single candle placed one foot away. In other words, it measures the luminous flux or light output distributed over an area.
A footcandle is an important concept in lighting design, as it helps determine the appropriate lighting levels needed for different environments and activities. It is widely used to specify lighting requirements in various settings, such as offices, homes, theaters, and outdoor spaces.
Footcandles are commonly used in the United States, while lux is the equivalent metric unit used in the International System of Units (SI). One footcandle is equivalent to approximately 10.764 lux. Conversion between the two units can be useful when comparing lighting measurements internationally.
By measuring the footcandles in a particular area, lighting designers can assess the adequacy or insufficiency of lighting levels. They can then make informed decisions about the number and types of light fixtures required to achieve the desired level of illumination.
Overall, footcandles play a pivotal role in the field of lighting design, providing a quantifiable measure of light intensity to ensure optimal lighting conditions for various activities and environments.

Etymology of FOOTCANDLE
The word "footcandle" is derived from the combination of two units of measurement: "foot" and "candle".
The term "foot" refers to the unit of length, which is equal to approximately 30.48 centimeters. It represents the average length of a human foot and has been used as a unit of measurement in various systems throughout history.
The term "candle" refers to the traditional unit of luminous intensity. Historically, it originated from the practice of using candles as a source of light. Luminous intensity is the amount of light emitted per unit solid angle, and "candle" was defined as the luminous intensity of a pure spermaceti candle weighing one-sixth of a pound (approximately 72 grams) and burning at a specific rate.
