Why this conversion matters in chemistry
Educational kitchen demonstrations hits this regularly. A 4 L stock-base batch breaks down into 16.91 US cups for per-portion distribution across a multi-recipe demonstration. The constant of 4.22675 cups per L reduces to 1 cup = 236.588 mL, the modern US definition. In practice you reach for it when a metric lab volume needs to be in the cup-stated instructions household chemistry, food prep, or consumer-product formulation work runs in. Note the US cup ≠ metric cup distinction: 1 L equals 4.227 US cups but exactly 4 metric (250 mL) cups.
Formula
cups = L × 4.22675
