Illuminance Converter

Light plays a critical role in our daily lives. From homes, offices, schools, hospitals, and factories to photography studios, streets, and stadiums—proper lighting is essential for comfort, safety, productivity, and health. Measuring and comparing light intensity accurately is therefore extremely important.

Illuminance is the scientific quantity used to measure how much light falls on a surface. However, illuminance is expressed in different units depending on the country, industry, or application. While Lux (lx) is the internationally accepted SI unit, Foot-Candles (fc) are still widely used in the United States and some other regions.

Manually converting between these units can be confusing and time-consuming. To make this process easy, smallwebtools.net offers a powerful and user-friendly Illuminance Converter that instantly converts between all common illuminance units with complete accuracy.

What Is an Illuminance Converter?

An Illuminance Converter is an online tool that converts values of light intensity falling on a surface from one unit to another.

Examples

• Lux (lx) → Foot-Candles (fc)

• Foot-Candles (fc) → Lux (lx)

• Phot → Lux

Instead of memorizing formulas or performing manual calculations, users simply enter a value, select the units, and get instant results.

Understanding Illuminance

What Is Illuminance?

Illuminance is a measure of how much luminous flux (visible light) is incident on a surface per unit area. In simple words, it tells us how bright a surface appears due to the light falling on it.

For example:

• A brightly lit office has higher illuminance

• A dim hallway has lower illuminance

Illuminance is different from brightness or luminance, which refers to light emitted or reflected from a surface.

SI Unit of Illuminance

The SI (International System of Units) unit of illuminance is the Lux (lx).

• 1 Lux = 1 lumen per square meter (lm/m²)

Lux is widely used in science, engineering, architecture, and international lighting standards.

Common Illuminance Units Explained

1. Lux (lx)

• SI unit of illuminance

• Used worldwide

• Common in lighting standards and regulations

2. Foot-Candle (fc)

• Imperial unit of illuminance

• Commonly used in the United States

• 1 fc = 10.764 lux

3. Phot (ph)

• Older CGS unit

• 1 phot = 10,000 lux

4. Millilux (mlx)

• Used for very low-light measurements
