Weight Calculator Help

Simply enter the density of the material in which your are interested, select the shape from the drop-down list, enter the dimensions, then hit the “Calculate” button. The weight will appear in both metric and common US units.

If you would like to use a typical density value for a material, simply select that material from the list in the Material Selection Box. The density used in the calculations will appear in the density box in g/cc.  If you prefer to see the density in other units, just click the units drop-down box next to the density, and the value will be converted for you automatically.
