Calculates cake weight from dimensions and density, or finds the right dimensions for a target weight. The unlocked value adjusts automatically when you change other values.
Lock icons
Each value (diameter, height, density) has a lock icon. The unlocked value adjusts automatically. For example: unlock diameter, change density — diameter recalculates to keep the same weight.
Find density: cake ø20×8 cm, weighs 2800 g
Volume = π×10²×8 = 2512 cm³ · Density = 2800 ÷ 2512 ≈ 1.11 g/cm³
Need 3 kg cake, height 10 cm, density 0.9 — what diameter?
Volume = 3000 ÷ 0.9 = 3333 cm³ · Radius = √(3333 ÷ (π×10)) ≈ 10.3 cm · Diameter ≈ 21 cm
Cake ø20 cm, 2.5 kg, density 0.9 — what height?
Volume = 2500 ÷ 0.9 = 2778 cm³ · Area = π×10² = 314 cm² · Height ≈ 8.8 cm
