How it works
A sphere's volume is (4 ÷ 3) × π × radius³.
Worked example
Radius 1 m. Volume = (4/3) × π × 1³ = 4.1888 m³.
Frequently asked questions
What's the difference between volume and surface area?
Volume is the space inside the sphere (m³); surface area is the skin around it (m²). Use the sphere surface area calculator for the latter.
Can I use the diameter instead?
Halve it first: radius = diameter ÷ 2, then enter the radius.
