Volume Calculator – Quick Cheat Sheet
Box: V = l × w × h
Cube: V = a³
Cylinder: V = π r² h
Cone: V = (1/3) π r² h
Sphere: V = (4/3) π r³
Capsule: V = π r² h + (4/3) π r³ (straight section h only)
Units: 1 m³ = 1,000 L; 1 L = 1,000 cm³; 1 in = 25.4 mm; 1 ft = 12 in; 1 US gal = 231 in³ ≈ 3.785411784 L.
Tip: Pick your Input Unit first; all fields use that unit.
Validation: Dimensions must be positive real numbers.
Notes & edge cases
“Capsule” assumes a cylinder of height h plus two hemispheres (radius r).
Displayed conversions: mm³, cm³ (mL), m³, in³, ft³, L, and US gallons.
Rounding: values are formatted for readability; click “Calculate” after editing any field.
