The Weight of a Cylinder calculator computes the weight (mass) of a cylinder based on the radius (r) and height of the cylinder (h), and the density of the material (mD). NEW: Weight of Steel Cylinders using millimeters and density of steel.
INSTRUCTIONS: Choose units and enter the following:
Weight of Cylinder (Wt): The weight / mass is returned in kilograms, with the volume of the cylinder in cubic meters. However, these can be automatically converted to compatible units via the pulldown menu.
The Math / Science
The weight or mass of a right circular cylinder formula computes the mass of a right cylinder as a function of the mean density (mD) of the composition and the volume calculated using the radius (r) of the base and the height (h). The default results will be in kilograms but can be converted to any of the system provided units. The formula for the weight of a cylinder is:
Wt=[π⋅r^{2}⋅h]⋅mD
where:
 Wt = weight of the cylinder
 r = radius of cylinder
 h = height of cylinder
 mD = mean density of the material in the cylinder.
The formula to compute the volume of the geometric shape based on the input parameters. Using the volume of a cylinder, the formula for mass from volume and density:
M = V • mD

Mean Density Lookup Function 
Mean density is scientifically volume divided by mass. There are various unit for density adopted by cultures and industries. Common units for density included the following:
 kilograms per cubic meter (kg/m^{3})
 grams per cubic centimeter (g/cm^{3})
 grams per liter (g/L)
 pounds per cubic feet (lb/ft^{3})
 ounces per cubic inch (oz/in^{3})
 pounds per barrel (lb/bbl)
 pounds per bushel (lb/bu)
If you want to identify a material by its density, use the Density Within Range tool.
Weight is technically the downward force that a mass exerts based on the force of gravity and the mass of the object. On the surface of the Earth, mass and weight are often interchanged. In some places, objects are sold by the gram (mass), and in other locations, the same objects are sold by the ounce (weight).
The Weight Calculators use the dimensions of an object and its shape to compute the objects volume. They then apply a density associated with a material to estimate the objects weight.
