How many wheelbarrows full is a yard of soil?

I'm curious to know, could you elaborate on how one might determine the number of wheelbarrows full that constitute a yard of soil? Is there a standard measurement for the capacity of a wheelbarrow that can be used as a reference? Or perhaps, it varies depending on the size and design of the wheelbarrow itself? Additionally, are there any specific factors that need to be considered when making this calculation, such as the weight or density of the soil? I'm eager to gain a better understanding of this question and how it relates to practical applications in landscaping or construction.
