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.

OmniCalculator.com

OmniCalculator.com is a popular website that provides thousands of free online calculators for various tasks. It has a Lumen Calculator (Lumen to Lux to Candela) that can help you convert between the three most popular units of measuring light: candelas, lumens, and lux. The calculator has candela, lumen, lux, source radiation angle, distance, and surface area as the parameters. You can add candela/lumen/lux value along with the distance to make the conversion. Apart from candela and lumen, the calculator supports multiple measuring units for the other parameters. You can pick the unit of choice for those parameters and easily perform your conversion. This calculator takes the conversion a step ahead with the angle of the radiation source. It can help you factor in a light source that is not directly parallel or vertical to the surface.
