What Is This Tool?
This converter allows you to translate luminance measurements from candela per square foot, an imperial unit, to millilambert [mL], a non-SI unit mainly used in imaging, cinematography, and broadcast engineering.
How to Use This Tool?
-
Enter the value in candela per square foot you wish to convert.
-
Select candela per square foot as the input unit and millilambert [mL] as the output unit.
-
Perform the conversion to get the equivalent luminance in millilambert [mL].
Key Features
-
Converts luminance values between candela/square foot and millilambert [mL].
-
Uses a precise conversion rate specific to these luminance units.
-
Supports applications in display calibration, photographic print measurement, and lighting design.
Examples
-
2 candela/square foot equals approximately 6.763 millilambert [mL].
-
0.5 candela/square foot equals approximately 1.691 millilambert [mL].
Common Use Cases
-
Measuring display and monitor brightness using imperial units.
-
Calibrating projector and cinema screen luminance in theater settings.
-
Converting legacy luminance values in imaging labs and broadcast engineering.
Tips & Best Practices
-
Ensure consistent unit selection to avoid confusion between imperial and non-SI units.
-
Use this converter when working across fields such as cinema, imaging, and lighting design that require both unit systems.
-
Be mindful of contextual differences when interpreting luminance values between these units.
Limitations
-
Both candela per square foot and millilambert are non-SI units, which may affect standardization.
-
Conversion involves approximations using π, potentially introducing small variances.
-
Candela per square foot is mainly applicable where imperial area measurements are standard, limiting its global use without conversion.
Frequently Asked Questions
-
What is candela per square foot used for?
-
Candela per square foot is used to specify luminance in settings where imperial area units prevail, such as display brightness or lighting design in theaters.
-
Why convert to millilambert [mL]?
-
Millilambert is common in cinematography and imaging labs for measuring luminance, making it useful for converting legacy or imperial-based luminance data.
-
Are these units part of the SI system?
-
No, both candela per square foot and millilambert are non-SI units used mainly in specialized fields.
Key Terminology
-
Candela per square foot
-
A non-SI luminance unit expressing luminous intensity per square foot, describing the brightness of a surface area in imperial units.
-
Millilambert [mL]
-
A non-SI luminance unit equal to one thousandth of a lambert, used mainly in cinematography and imaging to describe surface brightness.
-
Luminance
-
A measure of luminous intensity emitted or reflected by a surface per unit area in a given direction.
