Understanding Luminance Measurements
Luminance conversions are essential for various applications, from lighting design and photography to everyday measurements and environmental science. Understanding luminance conversions ensures accurate and consistent results across different measurement systems.
Common Luminance Units
Metric Units
- Candela per Square Meter (cd/m²)
- Nit (nt)
- Stilb (sb)
- Apostilb (asb)
Other Units
- Foot-lambert (fL)
- Lambert (L)
- Millilambert (mL)
- Candela per Square Foot (cd/ft²)
Common Applications
| Field | Measurement Types | Typical Uses |
|---|---|---|
| Lighting Design | Candela per Square Meter, Foot-lambert | Light fixtures, room lighting |
| Photography | Candela per Square Meter, Nit | Camera settings, image brightness |
| Display Technology | Nit, Foot-lambert | Screen brightness, display calibration |
| Environmental Science | Candela per Square Meter, Lambert | Light pollution, natural lighting |
Conversion Tips
- Use a luminance meter for precise luminance measurements
- For quick estimates: 1 foot-lambert = 3.426259 candela per square meter
- Remember that 1 nit = 1 candela per square meter
- For display brightness, use nits or foot-lamberts
- For lighting design, use candela per square meter or foot-lamberts
Luminance Conversions
| Conversion | Formula/Rule | Quick Answer |
|---|---|---|
| Candela per Square Meter to Foot-lambert | 1 fL = 3.426259 cd/m² | Divide cd/m² by 3.426259 |
| Foot-lambert to Candela per Square Meter | 1 cd/m² = 0.291863 fL | Multiply fL by 3.426259 |
| Candela per Square Meter to Nit | 1 nt = 1 cd/m² | 1 cd/m² = 1 nt |
| Nit to Candela per Square Meter | 1 cd/m² = 1 nt | 1 nt = 1 cd/m² |
| Candela per Square Meter to Lambert | 1 L = 3183.099 cd/m² | Divide cd/m² by 3183.099 |
| Lambert to Candela per Square Meter | 1 cd/m² = 0.000314 L | Multiply L by 3183.099 |
| Candela per Square Meter to Apostilb | 1 asb = 0.31831 cd/m² | Divide cd/m² by 0.31831 |
| Apostilb to Candela per Square Meter | 1 cd/m² = 3.14159 asb | Multiply asb by 0.31831 |
