What is a foot-lambert?

A foot-lambert is an imperial unit of luminance measuring the luminous intensity emitted or reflected from a surface per unit projected area in a specific direction.

Why convert from foot-lambert to millilambert?

Converting between these units helps users translate luminance values across different measurement systems used in cinema, imaging, and display calibration.

Can I use this tool to convert to SI units directly?

This tool converts foot-lambert to millilambert, which are legacy units; for SI conversions, additional steps or tools are required.

What Is This Tool?

This tool enables you to convert luminance measurements from foot-lambert, an imperial unit commonly used in cinema and home theater calibration, to millilambert, a non-SI unit used in cinematography and imaging. It helps translate values between different luminance standards for accurate calibration and specification.

How to Use This Tool?

Enter the luminance value in foot-lambert (fL) you want to convert
Select the target unit as millilambert (mL)
Execute the conversion to get the corresponding millilambert value
Use the result for display calibration, imaging analysis, or specification comparison

Key Features

Converts foot-lambert (fL) to millilambert (mL) accurately based on standard conversion rate
Browser-based and simple to use for quick luminance conversions
Useful for cinema, broadcast, and imaging luminance applications
Supports compatibility between imperial and non-SI luminance units

Examples

5 foot-lamberts equals 5.3819552085 millilamberts
10 foot-lamberts equals 10.763910417 millilamberts

Common Use Cases

Specifying and measuring projected-screen brightness for cinemas and home theaters
Characterizing luminance in photographic prints, film, and broadcast displays
Converting legacy luminance units for calibration in imaging labs and display manufacturing
Comparing display or projection brightness across different unit systems

Tips & Best Practices

Ensure the units relate to projected area and viewing direction for accurate conversion
Use this tool when dealing with imperial or legacy CGS luminance data
Cross-check converted values with SI candela per square meter standards if needed
Apply conversions carefully in calibration scenarios to maintain consistency

Limitations

Foot-lambert uses imperial units while millilambert is a non-SI legacy unit, which may affect precision
Modern luminance measurements more commonly use SI candela per square meter units
Proper interpretation of surface area and solid angle parameters is necessary to ensure accuracy
