What Is This Tool?

This tool converts illumination values from foot-candle, a non-SI unit measuring luminous flux per square foot, to lumen per square centimeter, a unit measuring brightness per unit area on a smaller metric scale.

How to Use This Tool?

  • Enter the illumination value measured in foot-candles into the input field.
  • Select foot-candle as the source unit if needed.
  • Choose lumen per square centimeter as the target unit.
  • Activate the conversion to get the equivalent luminous flux per square centimeter.

Key Features

  • Converts foot-candle values to lumen per square centimeter accurately using established conversion rates.
  • Supports applications in photography, horticulture, LED brightness measurement, and laboratory photometry.
  • Easy to use interface requiring just input of the foot-candle value for quick conversion.

Examples

  • Converting 10 foot-candles results in 0.01076391 lumen/square centimeter.
  • For 50 foot-candles, the equivalent is 0.05381955 lumen/square centimeter.

Common Use Cases

  • Setting lighting levels in offices and retail according to building codes.
  • Measuring exposure for photography, film, and stage lighting.
  • Calibrating LED brightness for small-scale electronic components.
  • Assessing illuminance on microscope slides in laboratory settings.
  • Controlling recommended light intensities in museums and greenhouses.

Tips & Best Practices

  • Verify unit selections before conversion to ensure accuracy.
  • Be mindful of the scale difference between square feet and square centimeters when interpreting results.
  • Use the tool for small-area or high-detail lighting applications where precise measurement matters.

Limitations

  • Foot-candle is a non-SI unit using square feet, while lumen per square centimeter is metric and much smaller in scale.
  • Conversion precision is important for measurements on very small surfaces.
  • Rounding errors can impact high-accuracy illumination calculations.

Frequently Asked Questions

What is a foot-candle?
A foot-candle is a non-SI unit of illuminance representing one lumen per square foot, commonly used in North America for lighting measurements.

How does lumen per square centimeter relate to lux?
One lumen per square centimeter equals 10,000 lux, reflecting the luminous flux per square meter scaled down to square centimeters.

Why convert foot-candles to lumen per square centimeter?
This conversion is useful for precise lighting assessments in small or detailed areas like LEDs, microscope slides, or display calibration.

Key Terminology

Foot-candle [ft*c, fc]
A non-SI illuminance unit equal to one lumen per square foot, used to quantify luminous flux incident on a surface.
Lumen/square centimeter
A photometric measure indicating luminous flux falling on one square centimeter surface area, weighted by the human eye's response.
