Quick start
- Enter concrete volume in cubic yards. Use the neat volume if you only want the shape weight.
- Enter density in pounds per cubic foot. Use 145 to 150 lb/ft3 for a rough normal-weight estimate, or use supplier data when you have it.
- Use waste percent only when you want the weight after adding an ordering cushion.
Best uses
Start here if one of these sounds like your job. The examples below show which inputs matter most.
- Estimate concrete weight for hauling, disposal, or trailer planning.
- Convert cubic yards into pounds and US tons.
- Compare normal-weight, lightweight, and heavier density assumptions.
- Add waste volume before estimating order weight.
What this calculator is solving
The Concrete Weight Calculator converts cubic yards into cubic feet, multiplies by the density you enter, and converts pounds into US tons. It is helpful for hauling, disposal, trailer, and rough planning checks when you already know the concrete volume.
Match each input label on the calculator to Use the calculator after you know the concrete volume. If you only know length, width, and thickness, calculate cubic yards first with the Concrete Calculator or Cubic Yard Calculator..
The formula in plain language
In plain language: The calculator multiplies cubic yards by 27 to get cubic feet, applies waste, multiplies adjusted cubic feet by density in pounds per cubic foot, and divides pounds by 2,000 to get US tons. The examples on the page are there so you can compare your inputs with a worked example before copying the answer.
The math is cubic yards x 27, then adjusted by waste, then multiplied by density in lb/ft3. The tons result is pounds divided by 2,000.
How to read the answer
Read the main result first. Then check the smaller lines for the totals, units, ranges, counts, or formula steps behind it.
- Total pounds is the main weight estimate.
- US tons is total pounds divided by 2,000.
- Cubic feet shows the adjusted volume used in the weight formula.
- Density used repeats the lb/ft3 value so you can spot a bad assumption quickly.
Common mistakes to avoid
If the answer looks strange, the most likely cause is a small input mismatch: a mixed unit, copied value, wrong mode, missing label, or result used for the wrong job.
- Do not assume every concrete mix weighs the same.
- Do not use a rough density when hauling limits or structural loads need exact numbers.
- Do not include rebar weight unless you calculate it separately.
- Do not mix up US tons and metric tonnes.
- Do not use waste percent if you only want the exact neat-shape weight.
Example: 2 cubic yards of normal concrete
Enter 2 cubic yards, 145 lb/ft3 density, and 0 percent waste. The calculator converts 2 cubic yards to 54 cubic feet.
Then it multiplies 54 by 145 to get 7,830 pounds. Dividing by 2,000 gives about 3.92 US tons.
Example: heavy estimate with waste
For 3.5 cubic yards at 150 lb/ft3 with 5 percent waste, the adjusted volume is 99.225 cubic feet.
That produces about 14,884 pounds, or about 7.44 US tons. This is the kind of check that helps before hauling or disposal planning.
Why density matters more than the calculator looks
Normal-weight concrete is often close enough to 145 to 150 lb/ft3 for a rough estimate, but lightweight concrete, air content, aggregate type, moisture, and reinforcement can change the real weight.
If the number affects a truck, trailer, crane, form, dumpster, disposal ticket, or structural load, use the supplier ticket, mix design, or project specification instead of a rough default.
Metric checks
People often ask for 1 m3 concrete weight in kg. A common normalweight estimate is about 2,400 kg per cubic meter.
This calculator stays in US units for now. Use a metric conversion check only as a rough comparison unless the project documents give a metric density.
Research and references
Concrete weight is a density problem. ACI defines normalweight concrete around 150 lb/ft3, and FHWA notes normal-weight concrete is often about 145 to 150 lb/ft3 while lightweight mixes can be lower.

FAQ in plain language
When should I use the Concrete Weight Calculator?
Use it when your task matches one of these common needs: Estimate concrete weight for hauling, disposal, or trailer planning. Convert cubic yards into pounds and US tons. It works best when you already know the measurements, amounts, units, or options the page asks for.
What is the Concrete Weight Calculator doing with my inputs?
In plain language: The calculator multiplies cubic yards by 27 to get cubic feet, applies waste, multiplies adjusted cubic feet by density in pounds per cubic foot, and divides pounds by 2,000 to get US tons. The examples on the page are there so you can compare your inputs with a worked example before copying the answer.
What do the main Concrete Weight Calculator inputs mean?
Cubic yards: the concrete volume you already measured or calculated from a slab, footing, column, or pour. Density: pounds per cubic foot. Normal-weight concrete is often estimated around 145 to 150 lb/ft3, while lightweight concrete can be much lower. Waste percent: extra volume before weighing, useful when you want the weight after adding an ordering cushion. US tons: the total pounds divided by 2,000, useful for hauling and disposal estimates.
How should I read the Concrete Weight Calculator answer?
Read the headline estimate first, then check the material, waste, coverage, and unit lines. For project tools, the supporting lines are often the difference between a rough idea and a list you can actually shop from.
What should I double-check before trusting the answer?
Concrete density varies by mix, aggregate, reinforcement, moisture, air content, and lightweight or heavyweight material choices. Use supplier data for truck limits, crane picks, disposal tickets, forms, or engineering decisions. Also check the unit, scale, mode, and result limit because small input changes can change the answer.
What density should I use for concrete weight?
For rough planning, normal-weight concrete is commonly estimated around 145 to 150 lb/ft3. Use your supplier or project specs when hauling, disposal, lifting, or structural loads matter.
How much does one cubic yard of concrete weigh?
At 150 lb/ft3, one cubic yard weighs about 4,050 lb, or about 2.03 US tons. At 145 lb/ft3, it weighs about 3,915 lb.
