One of the most basic differences between varieties, however, can be found in how much they weigh. For more information Please review the privacy policy, Disabling cookies will make it impossible to use member-related functions. The density of water is 1.0 g/mL at room temperature, so the specific gravity is equal to the density of the object expressed without a unit. WebSimply 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. That value must be known in order to determine the overall weight of said project and whether its other components will be able to support the heft of the plastic component - which is why we've put together this quick and easy guide on the weights of some of our most popular plastics.
