A standard gray 8-inch-by-8-inch-by-16-inch cinder block weighs about 37 pounds. This type of block has several variations and their weights are different based on these variations.

Without the characteristic two holes on top, the block that is 8 by 8 by 16 inches weighs 42 pounds. A block with a flat, rather than indented, surface at each end is 40 pounds. A half-size version of the full standard block weighs 24 pounds. A block that has been designed with a 45-degree corner weighs 33 pounds. The solid caps that are 8 by 4 by 16 inches for cinder blocks are 34 pounds.
