The amount (flux) of light incident at a distance of 1 foot from a standard candle.
the 'foot' measurement was derived from the length of the human foot. The word ''inch' was adopted from the Latin word 'unica' meaning a 12th part. The early English, having no measurement of their own adopted the 'unica' from 'unus' meaning one
As a new measurement, they measured King Henry's (I Think) foot. This is known as a "ruler"
Measuring "area" refers to determining size in two dimensions (e.g., length and width). The resulting measure is typically reported in terms of units of measurement "squared." For example, if a surface is one foot long and one foot wide, the area of the surface is called "one square foot" or "one foot squared."
a king invented it :)
A long time ago a king wanted to see how long his foot was. His foot was exactly 12 feet long so he called that a foot.

Because a king very long ago wanted to know how big his foot was.So he called his servants to measure his foot.Is foot appeared to be 12 inches long.Since the king's foot was the first thing measure,he decided to call 12 inches a foot.
A foot candle refers to the the amount of light a light bulb, sun.. etc puts out.
No, lumens and foot candles are not the same. Lumens measure the total amount of light output from a source, while foot candles measure the illuminance or light intensity on a surface. Lumens are used to describe the brightness of a light source, whereas foot candles are used to describe the light level at a specific point.
the foot was a measurement of the king's foot, which happened to be 12 inches long. Thus 1 foot = 12 inches.

One foot-candle is equal to the illumination produced by one candle from a distance of one foot away. It is a measure of illuminance used in lighting design and is equivalent to 10.76 lux in the metric system.
0.5 footcandle is a unit of measurement used to quantify the amount of light falling on a surface. It is equivalent to the illuminance produced by a candle from a distance of one foot.
The name 'foot' says it.
The measurement of my Dad is 6 foot.
