The Volume Calculator and Converter has two tasks on one page: convert a known volume, or calculate a complete solid from dimensions. Geometry covers rectangular prisms, cylinders, spheres and cones with labelled diagrams. The existing cubic and US liquid conversions remain available and update live.
Use conversion mode when the volume is known, and geometry mode when dimensions are known. The route remains conversions/volume; legacy mode=cube prism links remain valid. For packaging or price estimates use concrete or paint.
Conversion mode accepts a non-negative volume with source and result units. Prism dimensions are length, width and height. Cylinders and cones use radius and perpendicular height; spheres use radius only. Choose metres, centimetres, millimetres, feet or inches. Mode, shape, dimensions and unit values can be shared in the current URL.
Prism: V=lwh. Cylinder: V=πr²h. Sphere: V=4πr³/3. Cone: V=πr²h/3. Dimensions convert to metres before volume is calculated in m³. One litre is 0.001 m³, one cubic foot is 0.028316846592 m³, and one US gallon is 231 in³ or 3.785411784 L. Liquid conversion does not infer density or mass.
A 2×3×4 m prism has 24 m³ or 24000 L. A cylinder with radius 2 m and height 3 m has 12π≈37.699112 m³. The matching cone has 4π≈12.566371 m³. A sphere with radius 2 m has 32π/3≈33.510322 m³. In conversion mode, 1 US gal gives 3.785412 L when displayed to six decimal places.
立体の寸法を入力、または既知の体積を換算。 既知の体積を立方単位や液量単位に換算します。液量には米国単位を使用します。
寸法から体積を計算します。半径は直径の半分、高さは底面に垂直です。
寸法単位の変更は実際の大きさを保ちます。完全な立体が対象です。米ガロン・カップ・スプーンは体積であり重量ではなく、英単位や材料密度は使いません。
