Volume calculator
Volume of a box, cylinder, sphere or cone in cubic metres and litres.
1 m³ = 1,000 litres.
How this calculator works
Box: l × w × h. Cylinder: π r² h. Sphere: 4/3 π r³. Cone: ⅓ π r² h.
Worked example: a 1.2 × 0.8 × 0.5 m planter holds 0.48 m³, which is 480 litres of potting mix. A round tank 1 m in radius and 2 m high holds about 6,283 litres.
