Calculate volume of any 3D shape — cube, sphere, cylinder, cone and more.
Volume is the measure of three-dimensional space occupied by an object or enclosed within a container. It is expressed in cubic units — cubic meters (m³), cubic feet (ft³), cubic centimeters (cm³), liters, or gallons. Our volume calculator online computes the volume of all common 3D shapes including cubes, cylinders, spheres, cones, and rectangular prisms.
Aquarium sizing: Calculate water volume to determine filter capacity and stocking levels. Swimming pool volume: Essential for calculating chemical dosages. Concrete calculation: Volume of concrete needed for foundations and slabs. Tank capacity: Water tanks, fuel tanks, and storage containers. Cooking and baking: Converting between measurement units for recipes. Shipping: Volumetric weight calculations for courier charges.
1 Liter = 1,000 milliliters = 1 cubic decimeter. 1 cubic meter = 1,000 liters. 1 US gallon = 3.785 liters. 1 UK gallon = 4.546 liters. 1 cubic foot = 28.317 liters. 1 cubic inch = 16.387 ml. These conversions are essential when working with different measurement systems, especially for import/export, cooking with foreign recipes, and engineering specifications.
Archimedes' Principle: An object submerged in fluid displaces a volume of fluid equal to the object's own volume. This is how ships float despite being made of metal — the ship's hull encloses a large air volume, making its average density less than water. Volume calculation is also fundamental in fluid dynamics, thermodynamics, and understanding pressure-volume relationships in gases (Boyle's Law).
Volume is the amount of 3D space occupied by an object, measured in cubic units like cm³, m³, liters, or gallons.
Volume of cylinder = π × r² × h, where r is the radius of the base and h is the height.
Volume of sphere = (4/3) × π × r³, where r is the radius of the sphere.
Volume is the space an object occupies. Capacity is the amount a container can hold. A container's capacity equals its internal volume.
