🏗️ Concrete Weight Calculator
Calculate concrete weight based on dimensions and concrete type
How to Use This Calculator
Enter Concrete Dimensions
Input the length, width, and thickness of your concrete piece in inches. Measure all three dimensions accurately for precise weight calculations.
Select Concrete Type
Select the type of concrete (normal-weight, lightweight, heavyweight). Normal-weight concrete is standard at 150 lbs per cubic foot. Different types have different densities.
Calculate and Review
Click "Calculate Concrete Weight" to see concrete weight, volume in cubic yards, weight per cubic yard, and weight per square foot. Use this information for transportation and handling planning.
Plan Transportation
Use the calculated weight to plan transportation, verify equipment capacity, and estimate shipping costs. Heavy concrete requires strong equipment and careful planning.
Formula
Volume (cu ft) = Length (ft) × Width (ft) × Thickness (ft)
Convert Inches to Feet: Divide by 12
Weight (lbs) = Volume (cu ft) × Density (lbs/cu ft)
Weight per Cu Yd = Density (lbs/cu ft) × 27
Weight per Sq Ft = Thickness (ft) × Density (lbs/cu ft)
Example 1: Standard Concrete Slab (120" × 48" × 4", normal-weight)
Step 1: Convert to feet: 120" = 10 ft, 48" = 4 ft, 4" = 0.333 ft
Step 2: Calculate volume: 10 × 4 × 0.333 = 13.33 cu ft
Step 3: Calculate volume in cubic yards: 13.33 ÷ 27 = 0.494 cu yd
Step 4: Normal-weight density: 150 lbs/cu ft
Step 5: Calculate weight: 13.33 × 150 = 2,000 lbs
Step 6: Weight per cubic yard: 150 × 27 = 4,050 lbs/cu yd
Step 7: Weight per square foot: 0.333 × 150 = 50 lbs/sq ft
Example 2: Lightweight Concrete (96" × 36" × 6", lightweight)
Step 1: Convert to feet: 96" = 8 ft, 36" = 3 ft, 6" = 0.5 ft
Step 2: Calculate volume: 8 × 3 × 0.5 = 12 cu ft
Step 3: Lightweight density: 100 lbs/cu ft
Step 4: Calculate weight: 12 × 100 = 1,200 lbs

Frequently Asked Questions
How much does concrete weigh?
Normal-weight concrete weighs 150 pounds per cubic foot (4,050 pounds per cubic yard). Lightweight concrete weighs 100 lbs/cu ft, heavyweight concrete weighs 200 lbs/cu ft. Weight depends on concrete type and dimensions.
How much does a cubic yard of concrete weigh?
A cubic yard of normal-weight concrete weighs approximately 4,050 pounds (2.03 tons). A cubic yard is 27 cubic feet, so 27 × 150 lbs/cu ft = 4,050 lbs. This is the weight of one cubic yard of standard concrete.
How do I calculate concrete weight per square foot?
Weight per square foot = Thickness (feet) × Density (lbs/cu ft). For 4-inch (0.333 ft) normal-weight concrete: 0.333 × 150 = 50 lbs/sq ft. For 6-inch (0.5 ft) concrete: 0.5 × 150 = 75 lbs/sq ft. The calculator shows weight per square foot.
Does concrete type affect weight?
Yes! Concrete type significantly affects weight due to different densities. Normal-weight concrete is 150 lbs/cu ft, lightweight is 100 lbs/cu ft, heavyweight is 200 lbs/cu ft. Always specify the correct concrete type for accurate weight calculations.
Can I calculate weight for irregular shapes?
This calculator works for rectangular concrete pieces. For irregular shapes, calculate the volume manually (approximate as rectangular dimensions) and use the concrete density (150 lbs/cu ft for normal-weight) with the calculated volume.
How accurate is this calculator?
This calculator provides accurate estimates based on standard concrete densities. Actual weight may vary slightly based on specific mix design, aggregate type, moisture content, and curing conditions. Use the calculator as a guide and add safety margins for equipment capacity.
