How heavy is 2 yards of topsoil?

I'm curious about the weight of 2 yards of topsoil. Could you please explain to me how much it weighs, and if there are any factors that might affect its overall weight? Also, what tools or methods are commonly used to measure the weight of topsoil accurately? Additionally, is there a general range of weights that 2 yards of topsoil could fall within, or does it vary greatly depending on the specific type and quality of the soil? I'm interested in understanding this better to ensure that I can properly plan for my landscaping project.
