Volume Converter
To convert from unit A to unit B, first convert your value to the base unit (m/s²) using A’s factor, then convert to B by dividing by B’s factor. For a quick one-step conversion, use a direct multiplier: A factor ÷ B factor, then multiply your original value by that result.

Volume measures how much 3D space an object or substance takes up. The SI unit of volume is the cubic meter (m³). When we talk about a container’s volume, we usually mean its capacity—how much liquid it can hold—rather than the space the container’s walls occupy.
Most volumes are easy to find using standard formulas for common shapes. For irregular objects, you can often split the shape into smaller, simple parts and add them together, or use advanced math methods when needed. If you know a material’s uniform density, you can also calculate volume from its mass (or weight). This calculator helps you quickly compute volume for the most popular basic shapes.
What Is a Sphere?
A sphere is a perfectly round 3D shape—like a ball—where every point on its surface is the same distance from the center. That distance is the radius (r), and the longest straight line passing through the center from one side to the other is the diameter (d).
In math, a sphere is the surface, while a ball includes the space inside it—but both use the same radius, center, and diameter, so the volume calculation is the same.
What Is a Cone?
A cone is a 3D shape with a circular base that narrows smoothly up to a single point called the apex (vertex)—think of an ice-cream cone. In geometry, it’s formed by straight lines that connect every point around the base to the top point.
Here, we focus only on a finite right circular cone (a cone with a round base and a vertical height). Cones with non-circular bases or shapes that extend infinitely aren’t included.
What Is a Cube?
A cube is a 3D shape made of six equal square faces. At every corner (vertex), three faces meet, and each face joins its neighbors at a perfect 90° angle.
Because all edges are the same length, cubes are one of the simplest shapes to measure, making them a common example in geometry (also known as a special type of cuboid/parallelepiped).
What Is a Cylinder?
A cylinder is a 3D shape with two equal circular bases connected by a curved side—like a can. In everyday math, the term usually means a right circular cylinder, where the line through the centers of the circles is perpendicular to the bases.
A cylinder is defined by its radius (r) and height (h), which are the key values used to calculate its volume.
