Foot Candle Calculator
The Foot Candle Calculator is a handy tool designed to measure illuminance, providing insights into the brightness of a surface. It functions on a simple formula: Foot-candles (fc) = Lumens (lm) / Area (sq. ft). Let's break down this formula into simpler terms:
- Foot-candles (fc): This is the unit used to measure illuminance. It signifies the amount of light reaching a particular surface.
- Lumens (lm): The total light emitted by a light source, determining its brightness.
- Area (sq. ft): The space over which you wish to calculate illuminance, measured in square feet.
Understanding the Foot Candle Calculator helps in making informed decisions regarding lighting requirements, ensuring adequate brightness for various activities and settings.

Example of Foot Candle Calculator
Consider a scenario where you're designing an office space. Using the Foot Candle Calculator, you can input the lumens emitted by the lighting fixtures and the area of the workspace. This enables you to determine the appropriate foot-candle level required for optimal working conditions. For instance, an office environment may require around 30-50 foot-candles, ensuring a comfortable and productive atmosphere.
Most Common FAQs
Calculating the area involves multiplying the length and width of the space in feet.
The recommended levels vary based on settings:
Offices: 30-50 foot-candles
Homes: 20-30 foot-candles
Outdoors: Varies based on activities and safety requirements.
Using a light meter or referring to the light source's specifications can provide the lumens emitted.
