Concrete Weight Calculator
Find how much a volume of standard, lightweight or high-density concrete weighs, from a volume, an area and thickness, or dimensions.
Change the values and press Calculate to work out your own figures.
From a volume
Enter the volume and choose the type.
Show the working
- weight = volume × density
From an area and thickness
Enter the area and thickness and choose the type.
Show the working
- weight = volume × density
From dimensions
Enter the length, width and thickness and choose the type.
Show the working
- weight = volume × density
How to use it
Enter the volume and choose the type. Enter the area and thickness and choose the type. Enter the length, width and thickness and choose the type.
Lengths can be decimals, fractions or tape entries such as 12' 6 1/2" (in feet or inches). Prices are optional.
Key facts
weight = volume × density; standard concrete ≈ 150 lb/ft³ = 4,050 lb/yd³ ≈ 2,400 kg/m³
Reinforcement
Reinforced concrete weighs a little more, about 156 lb/ft³ with typical steel.
Questions
How much does a cubic yard of concrete weigh?
About 4,050 lb (3,700–4,220).
How much does 25 cu ft of concrete weigh?
About 3,750 lb.
Formulas

Limitations
- Material densities are typical values (the midpoint of the commonly published range); real loads vary with moisture, grading and compaction, so check with your supplier or type in their density.
- Tank results are the geometric volume; real tanks have wall thickness and fittings.
