Converted value
AI explanation
Formula
Converted value = amount × (from-unit-to-cd/m² factor) ÷ (to-unit-to-cd/m² factor)Worked example
300 nits to foot-lamberts
| Field | Value |
|---|---|
| Amount | 300 |
| From unit | nit |
| To unit | footlambert |
| Converted value | 87.559 |
Assumptions
- Nit and candela per square meter (cd/m²) are exactly the same unit under different names.
- 1 foot-lambert is derived from the exact international foot: 1 fL = (1/π) cd/ft² ≈ 3.4263 cd/m².
Frequently asked questions
Is "nit" the same as candela per square meter?
Yes — nit is simply a common name for candela per square meter (cd/m²), widely used in display/monitor brightness specifications.
What luminance is typical for a smartphone screen?
300-800 nits for typical indoor use, with many phones boosting to 1000+ nits in an "outdoor" or "HDR" brightness mode.
How is luminance different from illuminance?
Illuminance (lux, measured by the Illumination Converter) is light falling on a surface; luminance is light emitted or reflected from a surface toward the eye — what makes a screen or object appear "bright" to a viewer.
