How to Convert Candela/square inch to Bril

Converting Candela/square inch (cd/in²) to Bril (Bril) is a core calculation in Luminance, which measures the photometric luminous intensity emitted or reflected per unit area in a given direction. This calculation navigates the boundary between the International Metric System (SI) and British Imperial / US Customary engineering standards. In contemporary metrology, Imperial units are defined in terms of exact SI standards via international agreements—notably NIST SP 811 and the 1959 International Yard and Pound Agreement. Exactly 1 Candela/square inch equals 4.869478 × 10¹⁰ Bril, while 1 Bril equals 2.053608 × 10⁻¹¹ cd/in².

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (candela per square meter (cd/m²)) without arbitrary rounding:

Vtarget=Vsource×(ksource→SIktarget→SI)V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)
Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)
1. Source SI Bridge (ksource):1 cd/in² = 1550.0031 candela per square meter (cd/m²)
2. Target SI Bridge (ktarget):1 Bril = 3.183099 × 10⁻⁸ candela per square meter (cd/m²)
Step-by-step substitution for Candela/square inch → Bril:V(Bril) = V(cd/in²) × ( 1550.0031 / 3.183099 × 10⁻⁸ ) = V(cd/in²) × 4.869478 × 10¹⁰
Mathematical FormulaValue in Bril = Value in Candela/square inch × 4.86947835 × 10¹⁰Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 75 cd/in², applying the conversion factor yields exactly 3.652109 × 10¹² Bril. At larger operational scale, 5000 Candela/square inch corresponds to 2.434739 × 10¹⁴ Bril.

Inverse check: 1 Bril = 2.053608 × 10⁻¹¹ cd/in².
