The Circular Mass 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:
Circular Mass (m): 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 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
