What Is This Tool?

This converter allows you to change luminance measurements from apostilb, a traditional unit, into candela per square centimeter, which is commonly used for specifying brightness of small, intense light sources.

How to Use This Tool?

  • Enter the luminance value in apostilb you want to convert
  • Select apostilb as the input unit and candela per square centimeter as the output unit
  • Click the convert button to view the result
  • Use the converted value for your luminance analysis or specifications

Key Features

  • Converts luminance values from apostilb to candela per square centimeter with ease
  • Supports applications related to display engineering, lighting design, and cinematography
  • Browser-based tool requiring no installation
  • Facilitates interpretation of historical photometric data for modern contexts

Examples

  • 5 Apostilb converts to 0.000159155 Candela/square centimeter
  • 10 Apostilb converts to 0.00031831 Candela/square centimeter

Common Use Cases

  • Translating older photometric brightness data into units suitable for modern display components
  • Specifying brightness of LED indicators, OLED pixels, and other small emitting surfaces
  • Analyzing luminance of camera viewfinders and surgical lamps during design or quality control

Tips & Best Practices

  • Verify the input value and units before conversion to avoid errors
  • Understand that apostilb is a historical unit and may cause inconsistencies in SI-based systems
  • Use this conversion mainly for small-area luminance where candela per square centimeter is appropriate
  • Handle converted values carefully due to their very small magnitudes

Limitations

  • Apostilb being non-SI and historical may not align perfectly with contemporary measurement standards
  • Candela per square centimeter is typically suited for small light-emitting areas, not large surfaces
  • Due to the tiny conversion factor, numerical values in candela per square centimeter are very small, requiring precise calculation handling

Frequently Asked Questions

What is apostilb used for?
Apostilb is historically used for reporting screen brightness, describing diffusely reflecting surfaces, and calibrating imaging equipment in older photometric contexts.

Why convert apostilb to candela per square centimeter?
Converting apostilb to candela per square centimeter helps accurately specify brightness of small, intense light sources like LEDs and OLED subpixels in modern display technology.

Can this converter be used for large surface luminance?
Because candela per square centimeter is suitable for very small areas, this conversion is less ideal for luminance measurements involving large surfaces.

Key Terminology

Apostilb
A historical, non-SI luminance unit equal to 1/π candela per square metre, used in older photometric and cinematography measurements.
Candela per square centimeter
A non-SI luminance unit expressing luminous intensity per unit area, commonly used for small, high-intensity emitting surfaces.
Luminance
The luminous intensity emitted or reflected from a surface per unit projected area in a given direction.
