πŸ’‘ Cylinder Cubic Yardage for Concrete

For concrete piers and round footings, enter the diameter and depth in inches. The calculator converts to cubic feet and cubic yards, and estimates the number of 80-lb bags of premix concrete needed.

Standard Sonotube sizes: 8", 10", 12", 14", 16", 18", 20", and 24" diameter. A 12" Γ— 48" tube holds about 3.14 cu ft = 0.12 cu yd and needs 5–6 bags of 80-lb concrete mix.

A 12" diameter Γ— 48" deep pier: 3.14 cu ft = 0.12 cu yd. Needs 6 bags of 80-lb concrete. Four such piers: 12.57 cu ft = 0.47 cu yd = 21 bags.
