The final step will take the total weight of the asphalt required and convert it into tons. Take the last number you found and divide it by 2,000. [total asphalt required] / 2,000 =. Click here to know more about it. In this manner, how do you convert **square** feet **to tons** of **asphalt**? A **square yard** is 9 **sq** ft.For an **asphalt** pavement 4” thick the volume would be; 9 x (4/12)= 3 cubic feet.To determine how many **tons** or part there of is required divide by pounds per **ton** or 2000 for an imperial short **ton**.. Also Know, how do I **calculate** how much **asphalt** I need?. Converting from **cubic feet to metric tons (or tonnes**) is very easy. We know that 1 ft³ = 0.027863514087498 t . So, to convert 50 ft³ to t, multiply 50 ft³ by 0.027863514087498 t. 50 ft³ = 50 × 0.027863514087498 t. 50 ft³ = 1.3931757043749 t. Therefore, 50 cubic feet converted **to metric tons (or tonnes**) is equal to 1.3931757043749 t.
