Volume Calculator
Calculate volume of 3D shapes.
Formula: V = πr²h
Volume calculations matter for shipping estimates, pool and tank capacity, chemistry lab work, and geometry coursework. Utilitoo's Volume Calculator handles cubes, spheres, cylinders, and cones with the correct formula displayed alongside each result.
Warehouse managers estimating container space, homeowners calculating pool chemical doses, and students learning solid geometry all use volume calculators for quick accurate results. Select a shape, pick a unit, and enter dimensions - results update as you type.
Results show cubic units plus liters, cubic meters, and US gallons. Pair with Area Calculator for two-dimensional projects or Speed Calculator when combining volume with flow rate analysis.
All calculations run locally in your browser on Utilitoo. Free for engineers, students, and DIY planners.
Rectangular volume is length × width × height - the same formula whether you measure a cardboard box, a room, or a water tank. Utilitoo's Volume Calculator accepts your dimensions and returns cubic units instantly in the browser. For cylindrical or spherical containers, use a shape-specific formula instead; this tool targets the most common rectangular case in shipping and DIY projects. Write down which unit system you used (metric or imperial) when sharing results with others.
Common use cases
- Estimating shipping box volume for courier quotes and warehouse planning.
- Calculating tank, pool, or container capacity from length, width, and height.
- School or homework geometry exercises involving rectangular prisms.
- Quick sanity checks when converting between cubic units for construction materials.
- Comparing storage options when moving house or organizing warehouse shelf space.
Tips & common mistakes
Use consistent units for all three dimensions - mixing feet with inches produces wrong results. Volume formulas here assume rectangular shapes; irregular objects need different geometry. Results are estimates; verify critical measurements independently for engineering or construction work. When converting between cubic meters, liters, and cubic feet, write down intermediate values to catch unit mistakes. Shipping carriers may use dimensional weight instead of true cubic volume - check their rules. Liquids need container shape formulas beyond rectangular boxes. Area Calculator helps when you only need the base footprint first.
Common errors
- Mixed units - entering length in feet and width in inches without converting produces meaningless cubic output.
- Wrong shape assumption - this calculator is for rectangular prisms, not cylinders, spheres, or tapered containers.
How to use
- Select a shape and a length unit.
- Enter radius or side, plus height for cylinders and cones.
- Read volume in cubic units, liters, and US gallons.
Frequently Asked Questions
Which 3D shapes are supported?▼
Cube, sphere, cylinder, and cone volume calculations are available.
What units should I enter?▼
Pick mm, cm, m, inches, or feet. Utilitoo also shows liters, cubic meters, and US gallons.
How do I calculate cylinder volume?▼
Enter radius and height. Utilitoo applies V = πr²h.
Does it work for tank capacity?▼
Yes. Model a cylindrical tank with radius and height for capacity in cubic units.
Is my data uploaded?▼
No. Dimensions stay on your device. Cubic volume is calculated locally - nothing is uploaded.
