Definition:
Illuminance, measured in lux (lx) is a measure of the amount of light falling on a surface. One lux is equal to one lumen per square meter. The illuminance at a surface is calculated by dividing the luminous flux by the area of the surface. Illuminance is often used to measure the brightness of a room or other space, and it is typically measured in units of lux or foot-candles.
History/origin:
The concept of illuminance was first introduced by the German physicist Johann Heinrich Lambert in 1777 in his book "Photometria." In this book, Lambert defined illuminance as the density of the luminous flux on a surface. The unit of illuminance, the lux, was later introduced by the International System of Units (SI) in 1971.
Current use:
Illuminance is widely used in a variety of industries and applications. In the field of lighting design, illuminance is used to determine the appropriate level of lighting for a given space. In the field of photography, illuminance is used to measure the brightness of a scene. In the field of visual ergonomics, illuminance is used to measure the level of lighting in a work environment and to ensure that it is comfortable for the human eye. In the field of energy efficiency, illuminance is used to measure the energy efficiency of lighting systems.

In the above table, you can see the different units of illuminance and how they are related to one another. The table shows the conversion factors between these units. It is important to note that these conversion factors are exact, and they may vary slightly in real-world scenarios due to various factors like measurement errors, temperature variations and other factors.
In summary, the illuminance converter is an essential tool for measuring and comparing the brightness of a room or other space in different units. The conversion formulas and conversion table provided in this article will be useful for converting illuminance from lux to other units, making it easy to accurately measure and compare brightness levels in different industries and applications.
It is also important to note that these conversions can also be made for other units of area, such as square feet or square inches, by adjusting the conversion factor accordingly.
In the field of lighting design, illuminance is used to determine the appropriate level of lighting for a given space, such as a room or outdoor area. The recommended level of illuminance can vary depending on the type of space and the intended use. For example, a hospital operating room may require a higher level of illuminance compared to a residential living room.
In the field of photography, illuminance is used to measure the brightness of a scene, which is important for determining the correct exposure settings for a camera. Photographers use light meters to measure the illuminance of a scene and adjust their camera settings accordingly.
In the field of visual ergonomics, illuminance is used to measure the level of lighting in a work environment and to ensure that it is comfortable for the human eye. The recommended level of illuminance for a work environment can vary depending on the type of work being performed and the visual acuity of the worker.
In the field of energy efficiency, illuminance is used to measure the energy efficiency of lighting systems. By measuring the illuminance of a space and comparing it to the recommended level, energy efficiency experts can determine if a lighting system is operating efficiently.
In all the above applications, it is important to have accurate measurements of illuminance and the ability to convert between different units of illuminance. The illuminance converter is an essential tool that can help to ensure accurate measurements and conversions, making it easy to compare and analyze illuminance in different industries and applications.
In conclusion, the illuminance converter is a valuable tool that can help to ensure accurate measurements and conversions of illuminance in various industries and applications. The conversion formulas and conversion table provided in this article are useful for converting illuminance from lux to other units, making it easy to accurately measure and compare brightness levels in different industries and applications.
