How to Convert Bril to Watt/sq. cm/sr (at 555 nm)

Converting Bril (Bril) to Watt/sq. cm/sr (at 555 nm) (W/(cm²·sr) @555nm) is a core calculation in Luminance, which measures the photometric luminous intensity emitted or reflected per unit area in a given direction. Because Watt/sq. cm/sr (at 555 nm) is a broader physical scale than Bril, converting from Bril to W/(cm²·sr) @555nm condenses the numerical figure. It takes 2.145708 × 10¹⁴ Bril to equal a single Watt/sq. cm/sr (at 555 nm) (1 Bril = 4.660467 × 10⁻¹⁵ W/(cm²·sr) @555nm). To convert any quantity, multiply by 4.660467 × 10⁻¹⁵ (or divide by 2.145708 × 10¹⁴).

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 Bril = 3.183099 × 10⁻⁸ candela per square meter (cd/m²)
2. Target SI Bridge (ktarget):1 W/(cm²·sr) @555nm = 6830000 candela per square meter (cd/m²)
Step-by-step substitution for Bril → Watt/sq. cm/sr (at 555 nm):V(W/(cm²·sr) @555nm) = V(Bril) × ( 3.183099 × 10⁻⁸ / 6830000 ) = V(Bril) × 4.660467 × 10⁻¹⁵
Mathematical FormulaValue in Watt/sq. cm/sr (at 555 nm) = Value in Bril × 4.66046685 × 10⁻¹⁵Direct computational formula applied for standard conversion.
Worked Example

To convert 50 Bril (Bril) to Watt/sq. cm/sr (at 555 nm) (W/(cm²·sr) @555nm): multiply 50 by 4.660467 × 10⁻¹⁵ to get 2.330233 × 10⁻¹³ W/(cm²·sr) @555nm. At an industrial engineering scale, 240 Bril converts to 1.118512 × 10⁻¹² W/(cm²·sr) @555nm.

Inverse check: 1 W/(cm²·sr) @555nm = 2.145708 × 10¹⁴ Bril.
