Why weight varies
Moisture is the big variable. Dry, screened topsoil is lighter; wet clay-heavy soil is much heavier. Buying by the yard avoids paying for water weight.
Converting tons to yards and back
The conversion runs through cubic yards. 8 tons at about 1.2 tons per yard is 6.7 yards; multiply by 324 and divide by the depth in inches for square feet. At 3 inches that is roughly 720 square feet, and at 6 inches about 360.

Hauling it
Have it delivered or use a rated dump trailer at this weight. The topsoil calculator converts area and depth into yards.
Measuring accurately
Measure each bed or area in feet and multiply length by width for square feet. For curved beds, a rough rectangle around the shape overestimates; split it into smaller shapes instead. Measure the depth you actually want to add, not the total depth of the bed if some soil is already there.
Common mistakes
Many people underestimate settling, so beds end up low by the second season. Others pile soil or mulch against tree trunks and siding, which invites rot and insects. Wet, sticky soil should wait for a drier day before spreading.
Checking quality
Squeeze a handful: quality topsoil holds together loosely and breaks apart, rather than forming a sticky ball of clay or falling apart like sand. Avoid soil that smells sour or contains debris.
Weight and hauling
A cubic yard of soil can weigh a ton or more, and mulch roughly a quarter to half of that depending on moisture. Check your vehicle’s payload before hauling, and keep trailer loads within the rated capacity.
