Instructions
Measure the brick dimensions (length,width and height) using a ruler. For example, the brick size is 8 by 3 by 2 inches.
Multiply the length, width and height of the brick to calculate its volume. In this example, the volume of the brick is 8 x 3 x 2 = 48 cubic inches.
Multiply the volume in cubic inches by 0.000016 to convert it ti cubic meters. In this example, the brick volume is 48 x 0.000016 = 0.000768 cubic meters.
Find out the density of your brick (see Resources). Note that the density of common red bricks is 1,922 kilograms/cubic meter.
Multiply the volume by the density to calculate the brick weight. In this example, the weight is 0.000768 cubic meters x 1922 kg/cubic meter = 1.476 kg.
Multiply the weight in kilograms by 2.204 to convert it to pounds. In this example, the brick weight is 2.204 x 1.476 = 3.253 pounds.
