Weight of Concrete Calculator

When working on any construction project, knowing the weight of concrete is crucial. Whether you're pouring a concrete slab, building a block wall, or transporting ready-mix concrete, accurate weight calculations can save both time and money. That’s why we built this Weight of Concrete Calculator to help users like you get quick, reliable results based on your project dimensions and concrete type.

This tool is ideal for DIY homeowners, engineers, contractors, or students who want to calculate the weight of concrete in kilograms (kg), pounds (lbs), tons, or US tons, using either volume or dimensions.

What is the Weight of Concrete per Cubic Meter?

Concrete weight varies depending on its type and density. However, here are the standard values you can expect:

• Normal concrete: 2400 kg/m³
• Lightweight concrete: 1900 kg/m³
• Heavyweight concrete: 3500 kg/m³
• Reinforced concrete: 2500 kg/m³

So, if you’re calculating the 1m3 concrete weight in kg, the answer is typically around 2400 kg, depending on the type.

How to Use the Weight of Concrete Calculator

Using our tool is super easy. Just follow these steps:

1. Choose the shape

You can calculate concrete weight by entering dimensions for:

• Rectangular block
• Cylindrical block
• Direct volume entry (e.g., in m³, ft³, yd³, etc.)

2. Enter your dimensions

For rectangular or cylindrical shapes, input the required height, width, length, or diameter in your preferred units (meters, feet, inches, or centimeters).

3. Select concrete type

Choose the concrete type you're using. This adjusts the density used in the weight calculation:

• Normal
• Lightweight
• Heavyweight
• Reinforced
• Or input a custom density

4. Get the result

The calculator will instantly display the weight of concrete in kg, lbs, or tons, depending on your selected output unit.

Formula for Calculating Weight of Concrete

The formula used in the calculator is simple and based on real-world physics:

Weight = Volume × Density

Where:

• Volume is measured in cubic meters (m³) or converted from other units like ft³, in³, or cm³
• Density depends on concrete type (kg/m³, lb/ft³, etc.)

Example 1 – Rectangular Block

Suppose you have a concrete block that’s:

• Length: 2 meters
• Width: 1 meter
• Height: 0.2 meters

Volume = 2 × 1 × 0.2 = 0.4 m³

Weight = 0.4 × 2400 = 960 kg

Example 2 – Cylindrical Column

• Diameter: 1 meter
• Height: 2 meters

Radius = 1 / 2 = 0.5 m

Volume = π × 0.5² × 2 ≈ 1.57 m³

Weight = 1.57 × 2400 ≈ 3768 kg

Final Verdict

This Concrete Weight Calculator was created to make your life easier. Whether you're estimating the weight of a slab for transportation or calculating structural loads, this tool gives you quick, accurate results.

Not only does it support multiple shapes and units, but it also adapts to various concrete types and densities. From DIY concrete slabs to industrial concrete blocks, you’ll always get precise weight estimates in kg, lbs, or tons.

FAQs

How much does concrete weigh per m³?

Standard concrete weighs about 2400 kg per cubic meter. The weight can vary slightly based on the type and materials used.

What’s the weight of 1 cubic foot of concrete?

1 cubic foot of standard concrete weighs approximately 68 to 75 pounds (or around 1,600 to 2,400 kg/m³ depending on type).

How much does 4 cubic yards of dry concrete weigh?

4 yards × 2400 kg/m³ × 0.764555 m³/yd³ = ~7336 kg or around 16,175 lbs.

How heavy is a 6 ft × 2 ft × 2 ft concrete block?

Convert to meters:

• 6 ft = 1.8288 m
• 2 ft = 0.6096 m

Volume = 1.8288 × 0.6096 × 0.6096 = ~0.68 m³

Weight = 0.68 × 2400 ≈ 1,632 kg or ~3,598 lbs

Can I calculate weight in pounds or tons?

Yes! Just select the output unit as lbs, tons, or US tons from the dropdown in the calculator.
