Understanding Cubic Yards
In the United States, ready-mix concrete is universally sold by the cubic yard. One cubic yard is equal to a block that is 3 feet long, 3 feet wide, and 3 feet deep (27 cubic feet total). Converting your project dimensions into cubic yards is the fundamental first step of any concrete project.
Core Formula
Cubic Yards = Total Cubic Feet ÷ 27
Frequently Asked Questions
- How many bags of concrete make a cubic yard?
- It takes forty-five 80 lb bags or sixty 60 lb bags of premixed concrete to equal exactly one cubic yard.
- How much does a cubic yard of concrete weigh?
- A solid cubic yard of standard weight concrete weighs approximately 4,050 lbs (or about 2 tons).
- Can I just order by the square foot?
- No, square footage only measures area. You must multiply the square footage by the thickness (depth) in feet to determine the volume needed.
- What happens if I order too little concrete?
- Ordering a 'short load' to finish a pour incurs hefty delivery fees and can result in 'cold joints' where the first batch dries before the second is poured, compromising structural integrity.
