📐 The Q-Value Formula

Q = Σ (Qᵢ / Mᵢ) ≤ 1.0
Qᵢ = Net quantity of each DG per inner package
Mᵢ = Maximum net quantity allowed per package (from IATA DGR Packing Instructions)

When packing different dangerous goods together in one outer package ("All Packed in One"), the combined Q-Value must not exceed 1.0.
