What does LUX stand for?

The lux is the SI unit of illuminance, and is equal to 1 lumen per square meter.


How do you calculate a lux level in a room?

Light Level or Illuminance, is the total luminous flux incident on a surface, per unit area. The work plane is where the most important tasks in the room or space are performed.Measuring Units Light Level - IlluminanceIllumenance is measured in foot candles (ftcd, fc, fcd) (or lux in the metric SI system). A foot candle is actually one lumen of light density per square foot, one lux is one lumen per square meter. 1 lux = 0.0929 foot candle = 1 lumen /sq meter = 0.0001 phot1 ftcd = 1 lux / 10.7521 lumen/sq ft = 1 foot candle = 1x104 lux = 1 phot


How many meters is in one 1 square meter?

Technically, the answer is "un-defined" or un-answerable. They define 2 different types of measurement.A "meter" is a measurement of length, while a square meter is a measurement of area.Think of it in terms of the shape of a square that is 1 meter x 1 meter x 1 meter x 1 meter. You can define the perimeter length (which is what you might be asking for), and that = 4 meters (each of the sides of the square added together). The area of the square is 1 square meter, which you get by multiplying 2 sides of the square together, which in this case is 1 meter multiplied by 1 meter = 1 sq/meter.

What SI base unit is used to measure light?

The second.I see the "second" as a measure of time, not light.LUX, Lumen or Candela do ring a bell and something like watt per square meter..Yes the S.I. unit measure of light is a limen (lm) .lumen (lm)The SI derived unit for measuring the luminous flux of light being produced by a light source or received by a surface. The luminous intensity of a light source is measured in candela. One lumen represents the total flux of light emitted, equal to the intensity in candela multiplied by the solid angle in steradians (1/(4pi) of a sphere) into which the light is emitted. Thus the total flux of a one-candela light, if the light is emitted uniformly in all directions, is 4pi lumen.
