Convert Nanocandelas per square metre to Meganits
Convert Nanocandelas per square metre (ncd/m²) to Meganits (Mcd/m²) instantly and accurately.
Conversion Formula
Mcd/m² = ncd/m² × 1.000000000e-15
About Nanocandelas per square metre
The nanocandela per square metre (ncd/m²) equals 10⁻⁹ cd/m². Represents luminance at the threshold of cooled photomultiplier tubes and avalanche photodiode detectors. The darkest OLED black levels (~10⁻⁴ cd/m²) are still five orders of magnitude brighter; this unit is used in single-photon counting photometry. 1 ncd/m² = 10⁻⁹ cd/m².
About Meganits
The meganit (Mcd/m²) equals 10⁶ cd/m². The scale for extreme light sources: outdoor LED video walls at peak brightness reach 3-10 Mcd/m²; laser exit apertures are typically 10-10 000 Mcd/m²; the solar disc at zenith has luminance ≈1 600 Mcd/m² (1.6×10⁹ cd/m²). Used in laser safety and high-power illumination. 1 Mcd/m² = 10⁶ cd/m².
