What Is This Tool?
This converter allows you to convert luminance measurements from candela per square meter (cd/m²) to nit [nt], which are equivalent units commonly used to describe the brightness of surfaces and displays.
How to Use This Tool?
-
Enter the luminance value in candela per square meter
-
Select the target unit as nit [nt]
-
View the converted brightness value instantly
Key Features
-
Converts luminance units between candela per square meter and nit with a direct 1:1 ratio
-
Supports measurement contexts such as display brightness, lighting design, and signage
-
Provides clear definitions and typical use cases for both units
Examples
-
50 candela/square meter equals 50 nit
-
300 candela/square meter equals 300 nit
Common Use Cases
-
Specifying and comparing display brightness for TVs, monitors, and smartphones
-
Designing lighting and architectural elements to predict perceived brightness
-
Regulating luminance for road signs and vehicle instrument panels
-
Ensuring outdoor digital billboards meet daylight visibility requirements
Tips & Best Practices
-
Use the unit name that best fits the audience or industry standard
-
Remember that both units measure the same luminance despite differences in naming
-
Apply this conversion to communicate clearly about display brightness levels
Limitations
-
Candela per square meter and nit represent the same luminance quantity, so conversion is straightforward
-
Nit is a non-SI unit, so scientific contexts may prefer candela per square meter for formal documentation
Frequently Asked Questions
-
Are candela per square meter and nit different units?
-
No, they represent the same luminance quantity with a direct equivalence of 1 cd/m² equals 1 nit.
-
Why convert candela per square meter to nit?
-
Converting to nit aligns with common terminology in display and lighting industries, making brightness specifications easier to communicate.
-
When should I prefer candela per square meter over nit?
-
Candela per square meter is preferred in scientific and precise measurement contexts because it is the SI unit.
Key Terminology
-
Candela per square meter (cd/m²)
-
The SI unit of luminance that measures luminous intensity emitted or reflected from a surface per unit area in a given direction.
-
Nit [nt]
-
A non‑SI unit of luminance equal to one candela per square meter, commonly used to describe display and lighting brightness.
