Concrete Weight Calculator
Convert concrete volume or dimensions into planning weight, hauling loads, and optional per-ton cost.
What this calculator includes
Estimate concrete weight from a known volume or a rectangular placement. The calculator keeps density, overage, vehicle payload, and optional per-ton cost visible so you can replace planning assumptions with batch data, scale tickets, disposal rules, and the actual hauling setup.

Move from a weight check to shape-specific volume, ready-mix, bag, base, reinforcement, and form assumptions.
Open Concrete Calculator →How to use this concrete weight calculator
- 01
Choose volume or dimensions
Enter a known concrete volume, or calculate a rectangular volume from measured length, width, and thickness.
- 02
Replace the density
Use the approved mixture information, producer data, test data, or scale records when available; normal-weight and lightweight concrete differ.
- 03
Decide whether overage applies
Use zero for the weight of an existing measured volume, or an editable allowance when planning an order or uncertain debris quantity.
- 04
Verify hauling limits
Enter a conservative usable payload, then check vehicle tare, axle ratings, trailer ratings, legal limits, loading method, and disposal acceptance separately.
Worked example
Example: one cubic yard at 145 lb per cubic foot
One cubic yard contains 27 ft³. At an entered density of 145 lb/ft³ and zero overage, it weighs about 3,915 lb, 1.96 US tons, or 1,776 kg. A 1.5-ton usable payload would require two planning loads.
Practical buying and overage guidance
For new concrete, confirm mixture density and delivered volume with the producer. For removal, separate concrete from soil, asphalt, masonry, reinforcing steel, and other debris; obtain disposal acceptance, container weight limits, haul rates, and scale-ticket rules before loading.

Frequently asked questions
How much does one cubic yard of concrete weigh?
At the common planning density of 145 lb/ft³, one cubic yard weighs about 3,915 lb or 1.96 US tons. Actual density depends on the mixture and aggregate.
Does reinforced concrete weigh more?
Yes. This calculator estimates concrete only from entered density. Reinforcing steel, embedded items, coatings, attached masonry, soil, and mixed demolition debris must be added separately.
Should I include waste when weighing existing concrete?
Usually enter zero when the measured volume already represents the material being removed. Use an allowance only for measurement uncertainty or additional material and make that assumption explicit.
Can the load count tell me what truck to use?
No. It divides estimated weight by the entered payload. Vehicle configuration, tare, axle distribution, trailer and hitch ratings, road limits, loading, securement, and legal requirements still control.
Is wet concrete heavier than cured concrete?
Density changes with mixture proportions, entrained air, moisture, and concrete type. Use project-specific producer or test data whenever weight affects lifting, transport, or structural decisions.
