What Is This Tool?

This converter transforms luminance measurements from lumen per square foot per steradian, a non-SI unit, to kilocandela per square meter, an SI unit commonly used to represent brightness in photometry and display engineering.

How to Use This Tool?

  • Enter the luminance value in lumen per square foot per steradian.
  • Select 'lumen/square foot/steradian' as the input unit and 'kilocandela/square meter' as the output unit.
  • Click the convert button to see the result in kilocandela per square meter.
  • Refer to provided examples for guidance.
  • Use the conversion to interpret or report luminance in SI units.

Key Features

  • Converts non-SI luminance units (lumen/square foot/steradian) to SI units (kilocandela/square meter).
  • Browser-based tool requiring no installation.
  • Supports applications in lighting design, display technology, and outdoor signage measurement.
  • Includes example conversions for clarity.
  • Facilitates standardization in scientific and engineering contexts.

Examples

  • 10 lumen/square foot/steradian equals 0.107639104 kilocandela/square meter.
  • 50 lumen/square foot/steradian equals 0.53819552 kilocandela/square meter.

Common Use Cases

  • Measuring brightness of billboards and signs using U.S. customary units.
  • Lighting design assessments related to glare control and visual comfort using foot-based area units.
  • Calibrating and reporting luminance measurements from photometers in non-SI units.
  • Specifying peak brightness for HDR displays and televisions.
  • Establishing luminance standards for automotive HUDs and instrument panels.
  • Defining brightness criteria for outdoor LED billboards.

Tips & Best Practices

  • Always enter accurate input values to ensure correct conversion results.
  • Be aware that using non-SI customary units can introduce approximation errors.
  • Consider calibration and measurement conditions as luminance depends on these factors.
  • Use conversions to maintain consistency across international and scientific applications.
  • Check conversion examples to verify understanding.

Limitations

  • The from-unit uses non-SI customary area units which may cause rounding or approximation during conversion.
  • Luminance values depend on measurement setups and instrument calibration; thus, precision can vary.
  • This tool does not account for variations beyond simple unit conversion.

Frequently Asked Questions

What does lumen/square foot/steradian measure?
It measures luminance as luminous flux per unit area per unit solid angle, reflecting brightness in non-SI customary units.

Why convert lumen/square foot/steradian to kilocandela/square meter?
To standardize luminance values using SI units widely accepted in scientific, engineering, and international contexts.

Can this conversion be used for display brightness evaluation?
Yes, especially for specifying peak brightness of HDR displays, TVs, and automotive instrument panels.

Key Terminology

Lumen/square foot/steradian
A non-SI luminance unit measuring luminous flux per square foot per steradian, equivalent to candelas per square foot.
Kilocandela/square meter
An SI luminance unit equal to 1000 candelas per square meter, indicating luminous intensity emitted or reflected per unit area.
Luminance
A photometric measure of the luminous intensity per unit area projected in a specific direction.
