How Much Does a Yard of Concrete Weigh?
A cubic yard of concrete weighs about 4,050 pounds, or roughly 2 tons, when cured. Wet concrete is slightly heavier. This weight comes from concrete's density of about 150 pounds per cubic foot, times 27 cubic feet in a yard. The table below shows the weight of common amounts, useful for planning delivery and support.
| Cubic yards | Weight (lb) | Weight (tons) |
|---|---|---|
| 0.5 | 2025 | 1.0 |
| 1 | 4050 | 2.0 |
| 2 | 8100 | 4.1 |
| 5 | 20250 | 10.1 |

Calculate your exact amount with the concrete calculatorWhy Does a Yard of Concrete Weigh So Much?
A yard of concrete weighs about 4,050 pounds because concrete is dense: roughly 150 pounds per cubic foot, made of stone, sand, cement and water. Multiply 150 by the 27 cubic feet in a cubic yard and you get about 4,050 pounds. This is why concrete delivery trucks are so heavy and why slabs need a compacted base: the ground must support around 2 tons per cubic yard placed.
How Much Does a Bag of Concrete Weigh Mixed?
A bag of concrete weighs its labeled dry weight (40, 60 or 80 pounds), and slightly more once water is added for mixing. An 80-pound bag makes about 0.6 cubic feet of concrete. Since a full yard weighs about 4,050 pounds, and you need about 45 of the 80-pound bags per yard, the bag weights add up to roughly the same total. The calculator helps you plan both bag counts and total weight.
