This density of a cylinder calculator is helpful to determine the density of any cylindrical structure, given its mass and volume. If you're uncertain about the cylinder's volume, you can use its dimensions instead.
In this article, let's discuss some basic concepts:
- What is density?
- What is the formula for cylinder density?
- How to find the density of a cylinder?
What is density?
Density is the amount of mass of a substance per unit volume. It is given by:
- is the density of the substance;
- is the mass of the substance; and
- is the volume of the substance.
The SI unit of density is kilogram per cubic meter (), while its imperial unit is pound per cubic feet ().
Cylinder density formula
To derive a cylinder density formula, let's start by calculating its volume:
- is the cylinder's volume;
- is the cylinder's radius; and
- is the cylinder's height.
Combining this with the general formula for density we've seen in the previous section, we get the formula for cylinder density:
How do I find the density of a cylinder?
To calculate the density of a cylinder, follow these steps:
- Measure the mass m of the cylinder if it is not already known.
- Determine the cylinder's volume V from its radius r and height h using the formula V = πr2h.
- Divide the cylinder's mass by its volume to get its density ρ = m/v.
- Verify your results using our density of a cylinder calculator.
How to use this cylinder density calculator?
This density of a cylinder calculator is easy to use. It has two modes of calculation to suit your needs:
- In the default
Simple mode, you can enter the cylinder's
Volumeto calculate its density. Use this mode if both the mass and volume are known quantities.
- Using the
Advanced mode, you can also feed the cylinder's
Radiusinstead of its volume to calculate the cylinder's density. Use this mode if you don't know the cylinder's volume.

What is the density of a 500g cylinder with a 5cm radius and 10cm height?
636.6 kg/m3 is the density of this cylinder. To calculate this answer yourself, follow these steps:
- Calculate the cylinder's volume using V = πr2h to get V = π×(5 cm)2×(10 cm) = 785.40 cm3.
- Divide the cylinder's mass by its volume to get its density as ρ = (500 g)/(785.40 cm3) = 0.6366 g/cm3.
- Convert this density into SI unit to get ρ = 0.6366 × 1000 = 636.6 kg/m3.
- Verify this result using our density of a cylinder calculator.
How do I calculate the density of an oblique cylinder?
The density of an oblique cylinder is given by: ρ = m/πr2h. As long as you measure the cylinder's height h perpendicular to its base, the formula for the volumes of oblique and right cylinders are the same: V = πr2h. Hence, their densities will also be the same.
