Kalkulačka vína odhaduje láhve potřebné pro akci na základě počtu hostů, trvání akce a preferencí pití. Standardní láhev na víno o objemu 750 ml poskytuje 5 sklenic po 150 ml. Většina akcí přiděluje 2–3 sklenice na osobu na první hodinu plus 1 na další hodinu.

Calkulon makes complex calculations simple — built for students and everyday problem-solvers.
