Commonly Used Units
As stated earlier, the unit most commonly used for illuminance measurement is the lux (lx). The lux is one lumen per square meter, and it's a very easy unit to use. Lux is widely used and the standard unit for measuring illuminance in most industries and applications.
Lesser-Known Units: Lux is the standard unit for illuminance, but there are other lesser-known units that exist in certain fields as follows.
Footcandle (fc): A footcandle (as used in the U.S.) is that illuminance provided by one lumen of light uniformly distributed over a square foot surface area. To convert lux to footcandles, you can use the conversion factor: 1 lux = 0.0929 footcandles.
Candela per square meter (cd/m²): This unit indicates illuminance in terms of luminous intensity per square meter. It is applied in fields such as astronomy and radiometry, which require very accurate measurements of brightness.
How To Use Our Converter
Using Our Illuminance Converter is simple:
Input Illuminance Value: Fill in the input field with the illuminance value you wish to convert. This value means the light strength in this unit of measurement.
Select Unit: Select the current unit of illuminance from the dropdown menu.
Get the Result: Just press the "Convert" button, and our converter will instantly generate the converted results.

FAQs
What is illuminance?
Illuminance is the measure of how much light falls on a given area. It is typically measured in lux (lx), which is equal to one lumen per square meter. Illuminance is crucial in fields such as architecture, photography, agriculture, astronomy, and occupational safety.
Why is illuminance important?
Illuminance plays a vital role in various aspects of daily life and professional fields:
- Architecture: Helps in designing well-lit and comfortable spaces.
- Photography: Essential for capturing the right exposure and mood in photos.
- Agriculture: Critical for optimizing plant growth in environments like greenhouses.
- Astronomy: Used to measure the brightness of celestial bodies.
- Occupational Safety: Ensures proper lighting conditions to reduce accidents and eye strain in workplaces.
What units are used to measure illuminance?
The most common unit is the lux (lx). Other units include:
- Microlux (µlx): One-millionth of a lux.
- Millilux (mlx): One-thousandth of a lux.
- Kilolux (klx): One thousand lux.
- Foot-candle (fc): Used primarily in the United States; one foot-candle is equal to approximately 10.764 lux.
- Lumen per square meter (lm/m²): Equivalent to lux.
- Lumen per square centimeter (lm/cm²): Equal to 10,000 lux.
- Phot (ph): Equal to 10,000 lux.
- Nox: An older unit, equal to 0.001 lux.
- Candela per square meter (cd/m²): Also known as a "nit," it measures luminance.
How does the Illuminance Converter work?
The Illuminance Converter allows users to convert between different units of illuminance. Users input the value they wish to convert, select the current unit, and choose the target unit. The tool then provides the converted value using precise conversion factors.
When should I use an illuminance converter?
- International Collaboration: To standardize measurements when working with professionals from different countries.
- Compliance with Standards: To adhere to industry or regional standards specifying particular units.
- Quick Calculations: To save time and avoid errors compared to manual conversions
