Ball Volume Online Calculator

The ball is one of the fundamental geometric shapes. In real life, balls of perfect shape are not found very often, but at school or university you may encounter the task of calculating the volume of the ball. Either you need to make balls for the bearing or calculate the volume of basketballs. We suggest you use our simple and quick ball volume calculator. You can also convert the result to the desired measure of volume.

Use this online calculator to compute the volume of a sphere from either radius or diameter. Results appear in cm³, m³, in³, and ft³. Supported length units: centimetres (cm), metres (m), inches (in), feet (ft). Supported volume units: cubic centimetres (cm³), cubic metres (m³), cubic inches (in³), cubic feet (ft³).

How to use

Choose Measurement Type (radius or diameter).
Enter the numeric value and select its Unit (cm, m, in, ft).
Click Calculate. The canvas labels the chosen dimension; the results panel shows volume in all units plus radius, diameter, circumference, and surface area.

The radius of a ball is the distance from its center to its edge

Definitions of units

Centimetre (cm) — SI length unit. 1 m = 100 cm. Exact relation to inch: 1 in = 2.54 cm (exact).
Metre (m) — SI base length unit. 1 m = 39.3700787402 in (derived from 1 in = 2.54 cm exact) and 1 m = 3.280839895 ft. For volume, 1 m³ = 1,000,000 cm³ and 1 m³ = 1,000 L.
Inch (in) — US customary/imperial length unit. Defined exactly as 1 in = 2.54 cm. 12 in = 1 ft.
Foot (ft) — US customary/imperial length unit. 1 ft = 12 in = 0.3048 m (exact). 1 ft³ = 1728 in³.
Cubic centimetre (cm³) — SI-derived volume unit. 1 cm³ = 1 mL. Exact relation: 1 in³ = 16.387064 cm³.
Cubic metre (m³) — SI base volume unit. 1 m³ = 35.3146667 ft³ = 61,023.7441 in³ (exact factors).
Cubic inch (in³) — US customary/imperial volume unit. Exact relation: 1 in³ = 16.387064 cm³.
Cubic foot (ft³) — US customary/imperial volume unit. 1 ft³ = 1728 in³ = 0.028316846592 m³ (exact).

Formula

Sphere volume uses the formula V = (4/3)·π·r³. If diameter d is given, r = d/2; circumference on a great circle is C = 2·π·r; surface area is A = 4·π·r². Reference: Wolfram MathWorld — Sphere.
