What is an apostilb?
An apostilb is a specific unit of luminance, the luminance of a perfectly diffusing emitting light at the rate of pi^-1 candela per square metre.
What is the practical unit of electricity?
'Electricity' is not a quantity, so cannot be measured and, therefore, has no unit of measurement. It is the name of a field of study, just like 'chemistry', etc.A 'unit' of electrical energy is short for 'Board of Trade Unit' (a former government organisation that, at one time, set energy prices in the UK), and is exactly equivalent to a kilowatt hour, which is defined as the amount of energy consumed, over a period of one hour, at a rate of one kilowatt. A unit or kilowatt hour is equal to 3.6 million joules (a joule being the SI unit for energy), and normally costs around £0.15 to buy.

In what unit is luminance measured?
The unit of measurement for luminance in the International System of Units (SI) candela per square metre. In the Centimetre-gram-second system of units, the unit of luminance is the stilb.

What is the nonSI unit for temperature?
The SI unit for temperature is Kelvin.Kelvin = Celsius + 273Fahrenheit and Celsius are non SI units, however, Celsius is used in science as it is so easily converted to Kelvin.
What is an apostilb?
An apostilb is a specific unit of luminance, the luminance of a perfectly diffusing emitting light at the rate of pi^-1 candela per square metre.
What is photo luminance?
Luminance is a photometric measure of the luminous intensity per unit area of light travelling in a given direction. It describes the amount of light that passes through or is emitted from a particular area, and falls within a given solid angle. The SI unit for luminance is candela per square metre (cd/m2). Photo-Luminance is a technique through which we can find energy band gap Eg of a material generally a semiconductor. The sample is exposed to light and the photons emitted by the sample give the required information.
What is the difference between radiance and luminance?
Radiance is the amount of light energy emitted or reflected from a surface per unit solid angle, regardless of where it is being viewed from. Luminance, on the other hand, is the amount of light energy emitted or reflected from a surface per unit area as seen from a given viewing angle. In simpler terms, radiance is the total light output, while luminance is how bright it appears to an observer.

What is a footcandle vs a footlambert?
A footcandle is a unit of measurement for illuminance on a surface, equal to one lumen per square foot. A footlambert, on the other hand, is a unit of luminance, measuring the brightness of a surface emitting or reflecting light in footlamberts.
