What is Candela per Square Meter (cd/m²)?
Candela per Square Meter, also known as a nit, is a unit of luminance used to measure the brightness of a surface.
- Symbol: cd/m²
- Origin: It derives from the SI base unit of luminous intensity, the candela, and area in square meters.
- Significance: Commonly used in display manufacturing (TVs, monitors, smartphones), automotive dashboards, and lighting calculations.
- Real-world Example: A typical smartphone display might have a luminance of 500 cd/m².
Conversion Formulas and Explanation
- Candela per Square Meter to Foot-Lambert
Formula: Foot-Lambert = cd/m² × 0.2919
Example: 100 cd/m² = 29.19 Foot-Lamberts - Candela per Square Meter to Nit
Formula: 1 cd/m² = 1 Nit (They are equivalent)
Example: 250 cd/m² = 250 Nits - Candela per Square Meter to Stilb
Formula: Stilb = cd/m² ÷ 10,000
Example: 50,000 cd/m² = 5 Stilb
These conversions help standardize luminance measurements across different systems and applications.
