What Is This Tool?
This converter allows you to transform luminance measurements from nit, a common brightness unit in display technology, into lumen per square centimetre per steradian, a precise photometric unit used for characterizing small or high-intensity light sources.
How to Use This Tool?
-
Enter the luminance value in nit [nt]
-
Select 'nit [nt]' as the input unit and 'lumen/sq. cm/steradian' as the output unit
-
Click on the convert button to get the equivalent value
-
Review the converted value displayed in lumen per square centimetre per steradian
Key Features
-
Converts luminance units from nit [nt] to lumen/sq. cm/steradian accurately
-
Supports brightness level translation for display engineering and optical design
-
User-friendly interface suitable for professionals and enthusiasts
-
Browser-based tool requiring no installation

Examples
-
Convert 500 nits to lumen/sq. cm/steradian: 500 × 0.0001 = 0.05 lumen/sq. cm/steradian
-
Convert 1000 nits to lumen/sq. cm/steradian: 1000 × 0.0001 = 0.1 lumen/sq. cm/steradian
Common Use Cases
-
Specifying brightness levels for displays such as TVs, monitors, and smartphones
-
Defining brightness criteria for outdoor digital signage and billboards
-
Measuring luminance for vehicle dashboards and cockpit interfaces
-
Characterizing brightness of micro-LED and OLED pixels
-
Calibrating and testing luminance meters for small or intense light sources
Tips & Best Practices
-
Ensure units are correctly selected to avoid conversion errors
-
Understand the difference between square meters and square centimetres in unit definitions
-
Use lumen/sq. cm/steradian for detailed measurements of small or high-brightness sources
-
Verify conversion results with provided examples for accuracy
-
Keep in mind limitations when applying conversions in specialized optical contexts
Limitations
-
Difference in area units (square meters vs. square centimeters) requires careful unit management
-
Nit is a non-SI unit and may be less precise for small or intense light sources
-
Conversion may not fully represent angular or spectral weighting in some optical measurements
Frequently Asked Questions
-
What is a nit in luminance measurement?
-
A nit is a non-SI unit of luminance equal to one candela per square meter used to quantify perceived brightness from a surface.
-
What does lumen per square centimetre per steradian measure?
-
It measures luminous flux leaving or passing through a surface per unit area per unit solid angle, useful for small-area or high-intensity light sources.
-
Why convert from nit to lumen/sq. cm/steradian?
-
This conversion helps translate display brightness to photometric units ideal for optical design and measurement of fine details or very bright sources.
Key Terminology
-
Nit [nt]
-
A unit of luminance equal to one candela per square meter, used to express brightness of displays and lighting.
-
Lumen/sq. cm/steradian
-
A photometric luminance unit representing luminous flux per area per solid angle, equivalent to candela per square centimetre.
-
Luminance
-
A measurement of luminous intensity emitted or reflected from a surface per unit area in a given direction.
