» Volume of a Hemisphere


Calculate hemisphere volume from radius or diameter with V = 2/3 pi r^3. Convert cubic units and reverse solve a missing dimension.

Use this hemisphere volume calculator to find the volume of a hemisphere from radius or diameter using the standard formula V = 2/3 pi r^3.

It is useful for geometry, domed tanks, bowls, half-sphere containers, and cubic unit conversion. You can also reverse solve the missing radius or diameter from a known hemisphere volume.

Volume of a Hemisphere FAQ

What is the formula for the volume of a hemisphere?
The formula is V = 2/3 pi r^3, where r is the radius. A hemisphere has exactly half the volume of a sphere with the same radius.

Can I calculate hemisphere volume from diameter?
Yes. If you enter the diameter, the calculator converts it to radius and then applies the hemisphere volume formula automatically.

Can I convert hemisphere volume into liters or other units?
Yes. The result can be shown in different cubic units and liquid-capacity equivalents, depending on the unit system you need.

Can I solve for a missing radius or diameter?
Yes. Reverse calculation lets you find the missing radius or diameter when the hemisphere volume is already known.

When is a hemisphere volume calculator useful?
It is useful for bowls, domes, tank ends, molds, architectural features, and any half-sphere shape where you need an internal or external volume estimate.
