What Is This Tool?

This tool allows you to convert luminance measurements from millinit (mnt), a unit representing very low brightness levels, to apostilb (asb), a historic unit used in photometric and cinematographic applications. It helps translate modern decimal luminance values into older measurement standards.

How to Use This Tool?

  • Enter the luminance value in millinit (mnt) you wish to convert.
  • Select millinit as the source unit and apostilb as the target unit.
  • Click on the convert button to perform the calculation.
  • View the converted value in apostilb displayed instantly.
  • Use the formula and examples provided to verify results if needed.

Key Features

  • Converts luminance units from millinit to apostilb accurately.
  • Based on established conversion factors involving nits and candela per square metre.
  • Supports users in lighting engineering, display manufacturing, and historical photometric research.
  • Provides quick and simple conversion formula and examples.
  • Browser-based and easy to use, requiring no installation.

Examples

  • Convert 10 millinit: 10 × 0.0031415927 = 0.031415927 apostilb.
  • Convert 100 millinit: 100 × 0.0031415927 = 0.31415927 apostilb.

Common Use Cases

  • Describing very low display luminance levels such as night-mode or dimmed screen states.
  • Specifying brightness of low-luminance signage, instrument panels, or indicator lights.
  • Converting luminance data for compatibility with older photometric and cinematographic specifications.
  • Supporting lighting engineering literature on matte or diffusely reflecting surfaces.
  • Integrating new luminance measurements with historic photometric data for equipment calibration.

Tips & Best Practices

  • Ensure the input value is in millinit to use the correct conversion factor.
  • Verify conversions by cross-checking with the given formula and examples.
  • Be mindful that apostilb is a non-SI unit and may not be commonly used in all modern contexts.
  • Use this converter primarily for luminance values based on photometric definitions for best relevance.
  • Consult relevant industry standards when applying converted values in engineering or cinematography.

Limitations

  • Apostilb is a historical, non-SI unit and might cause confusion in modern standardization.
  • Conversion accuracy depends on constants derived from π and may vary accordingly.
  • Applicable mainly when luminance values are consistent with photometric measurement concepts.

Frequently Asked Questions

What does millinit measure?
Millinit is a unit of luminance representing one-thousandth of a nit, used to describe very low brightness levels emitted or reflected from surfaces.

Why use apostilb as a unit?
Apostilb is a historical unit used especially in older photometric and cinematographic contexts to describe luminance, facilitating comparison with legacy data.

Is apostilb an SI unit?
No, apostilb is a non-SI, historical unit of luminance and is less commonly used in modern measurement standards.

Key Terminology

Millinit [mnt]
A unit of luminance equal to one-thousandth of a nit, measuring low luminous intensity per unit area.
Apostilb [asb]
A non-SI historical unit of luminance equal to 1 divided by π candela per square metre, used in older photometric contexts.
Luminance
A measure of the luminous intensity emitted or reflected by a surface per unit area in a given direction.
