How do I calculate the volume of a cylinder?

Enter the radius of the base and the height of the cylinder into the calculator. The formula used is V = πr²h, where r is the radius and h is the height.

Can I calculate volume in different units like gallons or liters?

Yes, most volume calculators let you select the output unit. Choose your preferred unit from a dropdown menu after entering your dimensions.

What is the volume of a sphere with a radius of 5 cm?

Using the formula V = (4/3)πr³, a sphere with a 5 cm radius has a volume of approximately 523.6 cubic centimeters.

Is there a tool that also works as a volume conversion chart?

Yes, several tools in this group double as converters. You can input dimensions to get volume, then switch the output unit to convert between metric and imperial measures.

Do I need to convert my measurements to the same unit before calculating?

It is best to use the same unit for all dimensions. If your radius is in centimeters and height is in meters, convert one so both match before entering them.

Buyer's guide

How to choose a volume calculator

When picking a volume calculator, first identify whether you need to find the space inside a specific shape or convert between different volume units. If you are working with a geometric solid, look for a tool that lists the exact shape you need and lets you enter its dimensions — some tools only convert units, they don't calculate volume from measurements. If you are switching between units (like gallons to liters), a dedicated converter will be faster and may include cooking measures like cups and tablespoons. Also consider whether you prefer a clean, ad-free experience or don't mind ads for access to more unit options.
