Concrete Specifications
Concrete is one of the heaviest building materials, and knowing its weight is crucial for structural engineering, transportation planning, and equipment selection. This calculator helps you determine the weight of concrete structures based on their dimensions and the specific type of concrete used.
Understanding concrete weight is essential for:
- Planning transportation and lifting requirements
- Calculating structural loads on foundations
- Determining if floors or supports can handle the weight
- Estimating material costs based on weight
How to Use This Calculator
- Select your preferred measurement units (imperial or metric)
- Choose the shape of your concrete structure (rectangular or cylindrical)
- Enter the dimensions of your concrete structure
- Select a concrete type or enter a custom density
- Click "Calculate Concrete Weight" to get your results
Concrete Density Information
The density of concrete varies based on its composition:
- Standard Concrete: 150 lbs/ft³ (2,400 kg/m³)
- Lightweight Concrete: 120-140 lbs/ft³ (1,920-2,240 kg/m³)
- High-Density Concrete: 160-180 lbs/ft³ (2,560-2,880 kg/m³)
- Reinforced Concrete: 155-160 lbs/ft³ (2,480-2,560 kg/m³)

Frequently Asked Questions
A cubic yard of standard concrete weighs approximately 4,050 pounds (2.025 tons) or 1,840 kilograms. This can vary based on the specific mix, with lightweight concrete weighing less and high-density concrete weighing more.
A 4-inch (0.33 ft) thick standard concrete slab weighs about 50 pounds per square foot (150 lbs/ft³ × 0.33 ft = 50 lbs/ft²). This is important to know when determining if an existing structure can support a new concrete installation.
Concrete weight is critical for structural design calculations, transportation logistics, crane capacity planning, and foundation load assessments. Underestimating concrete weight can lead to structural failures, transportation issues, or lifting accidents.
Yes, adding steel reinforcement (rebar) increases the weight of concrete. Steel has a density of about 490 lbs/ft³, which is over three times the density of concrete. For heavily reinforced concrete, the weight can increase by 5-10% compared to plain concrete.
