Capsule Volume Calculator
Calculates the total volume of a capsule-shaped object (cylinder with two hemispherical ends).
Calculates the total volume of a capsule-shaped object (cylinder with two hemispherical ends). Enter your Radius (r), Cylinder Height (h) to get an instant capsule volume. Formula: (3.141592653589793 * pow(r, 2) * h) + ((4 / 3) * 3.141592653589793 * pow(r, 3)).

How It Works
How It Works
The Capsule Volume Calculator finds the total volume of a capsule-shaped object, which is made of a cylinder in the middle and two rounded ends that form a full sphere. You enter the radius (r) and the height (h) of the cylindrical section only.
The calculator applies this exact formula: (3.141592653589793 * pow(r, 2) * h) + ((4 / 3) * 3.141592653589793 * pow(r, 3)). The first part calculates the cylinder’s volume, and the second part calculates the volume of the two hemispheres combined (which equal one full sphere).
- Radius (r) is used for both the cylinder and the rounded ends.
- Cylinder height (h) includes only the straight middle section.
- The first term calculates πr²h (cylinder volume).
- The second term calculates (4/3)πr³ (full sphere volume).
- Both parts are added to get the total capsule volume.
Understanding the Results
The result is a single number labeled "Capsule Volume." It represents the total space inside the entire shape, including the cylindrical body and both rounded ends.
The output is expressed in cubic units, based on the unit you used for radius and height. For example, if you enter meters, the result will be in cubic meters.
- The value shows the total internal volume of the capsule.
- Units are cubic versions of your input units (e.g., m³, ft³, in³).
- If you double the radius, the volume increases significantly.
- If you increase only the height, only the cylindrical portion grows.
Frequently Asked Questions
What does the Capsule Volume Calculator compute?
This calculator computes the total volume of a capsule-shaped object, which consists of a cylindrical middle section and two hemispherical ends. It adds the volume of the cylinder (πr²h) and the volume of a full sphere ((4/3)πr³). The result is returned as a single numeric value representing the total volume.
When should I use this calculator?
Use this calculator when you need to determine the volume of objects shaped like capsules, such as tanks, pills, storage containers, or pressure vessels. It is especially helpful in engineering, manufacturing, and scientific applications where accurate volume measurements are required.
Does the cylinder height include the hemispherical ends?
No, the cylinder height (h) should only include the straight middle section of the capsule. Do not include the curved hemispherical ends in this measurement. The calculator automatically accounts for the two hemispheres by adding the volume of a full sphere.
What units should I use for radius and height?
You can use any unit of measurement (such as meters, inches, or feet), as long as both the radius and height use the same unit. The output will be in cubic units corresponding to your input, such as cubic meters or cubic inches.
Why does the formula include the volume of a full sphere?
A capsule has two hemispherical ends, and two hemispheres together make one full sphere. Instead of calculating each hemisphere separately, the formula simplifies the process by adding the volume of a full sphere ((4/3)πr³). This ensures accurate and efficient computation.
What happens if I enter zero or negative values?
The radius and cylinder height must be positive numbers for the formula to produce a meaningful result. If you enter zero or negative values, the calculated volume may be zero or mathematically invalid. For accurate results, always provide positive numeric inputs.
