7 Best Free Online Candela to Lux Conversion Calculator Websites

Here is a list of the best free online Candela to Lux Conversion Calculator websites. Candela is the SI unit of luminous intensity. It measures the amount of light emitted in a particular direction by a light source. On the other hand, Lux is the SI unit of illuminance. It measures the amount of light that falls on a surface per unit area. Lux is derived from Candela and meters squared, following is the formula for lux conversion:

Lux = Candela / Distance².

As the distance from the light source increases, Lux decreases. This is because the same amount of light is spread over a larger area. Lux value depends on the distance from the light source, it can not be directly used from a candela measurement. You have to perform a conversion with the specific distance for the lux value. This post covers 7 websites where you can convert Candela to Lux online. These websites provide simple tools where you can add your values and quickly perform the conversion.

Frequently Asked Questions

Candela is the SI unit of luminous intensity, measuring the amount of light emitted in a particular direction by a light source.

Lux is the SI unit of illuminance, measuring the amount of light that falls on a surface per unit area.

Lux is derived from Candela and meters squared (lx = cd/m²). It represents the intensity of light at a specific point on a surface.

Lux = Candela / Distance². The distance is measured in meters.

As the distance from the light source increases, Lux decreases because the same amount of light is spread over a larger area.

No, the Lux value depends on the distance from the light source, so the conversion must consider the specific distance.

Yes, the conversion is applicable to all light sources, provided you know the luminous intensity in Candela and the distance.

Candela is typically measured using a photometric sphere, integrating sphere, or other calibrated instruments.
