Oblate Spheroid Volume Calculator (V = ⁴⁄₃πa²c)
This calculator computes the oblate spheroid volume: exact formula V = ⁴⁄₃πa²c, worked example a = 6 cm, c = 3 cm → V = 452.39 cm³, e² = 0.75.

How the oblate spheroid volume Calculator Works
The calculator applies the exact formula V = ⁴⁄₃·π·a²·c, e² = 1 − c²/a². Worked example: a = 6 cm, c = 3 cm → V = 452.39 cm³, e² = 0.75. Keep every input in one unit system and the result follows in cubic units (m³, ft³, liters); full precision is kept until the final rounding. Radius fields expect radii — halve any diameter before entering it.

Tips
- 1
Volume scales with the cube of linear dimensions
- 2
Convert results: 1 m³ = 1000 L, 1 ft³ = 7.48 US gal
- 3
π ≈ 3.14159 — precision kept to the last step
Common Mistakes
Mixing units (cm radius with m height)
Entering a diameter where the formula wants a radius
Forgetting the solid must be closed — check h > 0
