CALCULATOR
Sphere Volume Calculator
Find the volume of a complete sphere from its radius in meters.
How the calculation works
Volume = 4π × radius³ / 3.
Worked example
With radius 2 m, sphere volume is 33.51032164 m³.
Assumptions and limits
Forward volume calculation for a complete sphere. Enter radius in meters, from 0.001 to 10,000; radius is half the diameter. Use the internal radius for capacity. No inverse solving, hollow-shell or partial-fill model.
