What Is This Tool?

This converter transforms measurements of luminance from millilambert, a traditional unit often used in cinematography and imaging, into lumen per square centimetre per steradian, a modern photometric unit suited for precise brightness measurement on small or bright surfaces.

How to Use This Tool?

  • Enter the luminance value in millilambert (mL)
  • Select millilambert as the input unit and lumen/sq. cm/steradian as the output unit
  • Click the convert button to get the equivalent luminance in lumen per square centimetre per steradian
  • Review the result and utilize it for your specific luminance evaluation or calibration needs

Key Features

  • Supports conversion between millilambert (mL) and lumen/sq. cm/steradian units
  • Facilitates translation of legacy luminance values into specialized photometric units
  • Includes clear conversion formula and practical usage examples
  • Useful for applications in cinematography, imaging labs, and micro-scale light source measurement
  • Browser-based and easy to use with no installation required

Examples

  • 5 Millilambert [mL] equals approximately 0.0015915495 Lumen/sq. cm/steradian
  • 10 Millilambert [mL] equals approximately 0.003183099 Lumen/sq. cm/steradian

Common Use Cases

  • Specifying display and projector screen luminance in cinematography and broadcast engineering
  • Characterizing photographic prints, film, and lightbox luminance in imaging laboratories
  • Calibrating and testing luminance meters for small-area or high-intensity samples
  • Measuring brightness of micro-LED or OLED pixel emitters in high-precision optical design
  • Converting historically used luminance units into modern SI-based values for analysis

Tips & Best Practices

  • Verify unit selections before conversion to ensure accuracy
  • Use this tool primarily for small-area or high-brightness photometric assessments
  • Consider the legacy nature of millilambert when interpreting converted results
  • Apply conversions carefully when calibrating sensitive luminance measurement instruments

Limitations

  • Millilambert is a non-SI, mostly outdated unit which may cause rounding approximations
  • Lumen/sq. cm/steradian is specialized for micro-scale luminance and may not suit larger surfaces
  • Interpreting results requires understanding of the units’ appropriate contexts
  • Conversion should be used cautiously in generalized luminance assessments beyond high-precision needs

Frequently Asked Questions

What is a millilambert used for?
Millilambert is primarily used in cinematography, broadcast engineering, and imaging labs to specify luminance of displays, photographic prints, and films.

How does lumen/sq. cm/steradian relate to candela per square centimetre?
Lumen per square centimetre per steradian is equivalent to candela per square centimetre, representing luminous intensity per unit area.

Can I use this conversion for large surface luminance measurements?
This conversion is best suited for small or high-brightness areas; for larger surfaces, the units and conversion may not be appropriate.

Key Terminology

Millilambert (mL)
A non-SI unit of luminance equal to one-thousandth of a lambert used to quantify luminous intensity per unit area and solid angle.
Lumen/sq. cm/steradian
A photometric unit measuring luminous flux per unit area per unit solid angle, equivalent to candela per square centimetre.
Luminance
A photometric measure of the luminous intensity per unit area of light travelling in a given direction.
