Illuminance Converter

Welcome to our Illuminance Converter, a handy tool for students, professionals, and enthusiasts of lighting, photography, and architecture. This tool helps you quickly convert illuminance units while keeping your results accurate and easy to use.

What is the Illuminance Converter Tool?

• The Illuminance Converter Tool allows you to convert illuminance to the unit you need, no matter what unit you start with. It has nine different units of illuminance. Below you can see how they compare to lux.
• Lux to microlux = 4000000
• Lux to millilux = 4000
• Lux to lux = 4
• Lux to kilolux = 0.004
• Lux to lumens per square meter = 4
• Lux to lumens per square centimeter = 0.0004
• Lux to footcandles = 0.36000000036
• Lux to photons = 0.0004
• Lux to nox = 4000

Why do You Need an Illuminance Converter tool?

Since the beginning of science, measuring things has been important. Today, both measuring and converting values ​​are more important.
This tool provides rounded results so that numbers are short and clear. You can use it online on any device. It saves time by providing quick answers without lengthy manual work. Engineers, students, and people who often use different units find it very useful.

How to use the Illuminance Converter tool?

Follow these steps to get the illuminance you need:

• Type the illuminance value you want to convert.
• Select the unit of the value you entered.
• Click Calculate to see the result.

To make the conversion process easier, we will go through the main light units and their conversion values.

Lux (lx): Lux is the standard SI unit for light level. It indicates how many lumens fall on one square meter.

Conversion factor: 1 lx = 1 lm/m²

Meter-candle (m•c): This is an old unit for light level. It means the same as lumens per square meter.
Conversion factor: 1 m•c = 1 lm/m² = 1 lx

Centimeter-candle (cm•c): This old unit shows the lumens falling on one square centimeter.
Conversion factor: 1 cm•c = 1 lm/cm² = 10000 lx

Foot-candle (f•c): This non-SI unit was used before. It shows the lumens falling on one square foot.
Conversion factor: 1 f•c = 1 lm/ft² = 10.764 lx

Flame (flame): This unit represents the brightness of a candle. One flame is equal to 4 lumens per square foot.
Conversion factor: 1 flame = 4 lm/ft² = 43.056 lx

Photo (ph): A photo is another unit of light. One photo is equal to one centimeter-candle or 10 kilolux.

Conversion factor: 1 ph = 10000 lx

Nox (nx): A nox is used for very low light, such as at night. It is equal to one millilux.

Conversion factor: 1 nx = 0.001 lx

Lumen per square meter (lm/m²): This represents the light from one lumen spread across one square meter.

Conversion factor: 1 lm/m² = 1 lx

Lumen per square centimeter (lm/cm²): This represents the light from one lumen spread across one square centimeter.
Conversion factor: 1 lm/cm² = 10000 lx

Lumen per square foot (lm/ft²): This represents the light from one lumen spread across one square foot. It is mostly used in the US.
Conversion factor: 1 lm/ft² = 10.764 lx

Watt per square centimeter (W/cm²): This unit represents power per area. The relationship between lux and W/cm² varies with the type of light. At 555 nm, one watt is equal to 683 lumens.
Conversion factor: 1 W/cm² (at 555 nm) = 683 lm/cm²
