Volume of a Sphere Calculator
Formula
V = (4/3) × π × r³
Find sphere volume from radius or diameter for manufacturing, packing, and geometry-based volume estimation.
Formula
Volume = (4/3) * pi * r^3
Worked Example
radius5
Result: 523.60 cubic unitsVolume scales with the cube of radius, so small radius changes can produce large volume differences.
Frequently Asked Questions
Can I input diameter directly?
Yes. Convert with r = diameter / 2 before applying the sphere volume formula.
Why is radius sensitivity so high?
Because radius is cubed in the formula, doubling radius increases volume by a factor of eight.
