How Do I Convert Cubic Feet to Cubic Yards of Concrete? (With Conversion Formulas)

If you’re pricing out a driveway, patio, or footing, the first practical question is always how much is a yard of concrete going to cost on your job. The answer depends entirely on accurately converting your cubic feet measurements into cubic yards before you call the batch plant. This guide walks you through the exact formulas, tables, and pricing logic that estimators and site engineers rely on every day.

By the end, you’ll know how to calculate cubic feet from raw dimensions, convert them to yards, and cross-check the weight in tons so your order matches the truck capacity exactly.

How Much Is a Yard of Concrete? Quick Answer & Pricing Overview

So, how much is a yard of concrete right now? Nationally, ready-mix concrete typically runs between $125 and $180 per cubic yard delivered, before pumping or finishing labor.

Prices swing based on regional aggregate costs, mix design (3000 PSI vs 4000 PSI), and how far the plant has to drive. Rural sites and high-strength mixes push the price toward the top of that range.

Orders smaller than 5 cubic yards usually trigger a short-load fee of $50–$100 per yard extra, since plants prefer dispatching full trucks. This is exactly why getting your volume math right before ordering saves real money.

Understanding Cubic Feet vs Cubic Yards in Concrete Work

Before you can nail down how much is a yard of concrete you actually need, you have to understand the two units doing all the work. This is the foundation of how to calculate cubic feet for any concrete pour, and it directly determines how to find cubic feet on your own takeoff sheets.

A cubic foot is a cube measuring one foot on every edge. How big is a cubic foot in smaller units? It equals exactly 1,728 cubic inches (12 × 12 × 12), which is useful if you’re translating inch-based drawings using how to calculate cubic inches for footings or post holes.

If you’re wondering how many inches is cubic feet, remember it’s not a direct swap — inches measure length while cubic feet measure volume, so always convert through the 1,728 figure first. A cubic yard, by comparison, is a cube measuring 3 ft × 3 ft × 3 ft, meaning one cubic yard always equals 27 cubic feet.

How Do I Find the Cubic Feet of a Concrete Slab?

To answer how do i find the cubic feet of a slab, multiply length (ft) × width (ft) × thickness (ft). The same approach works for how to figure cubic feet of walls, columns, and footings.

Example: a slab 10 ft long, 10 ft wide, and 0.5 ft thick (6 inches) equals 50 cubic feet. Learning how to measure cubic feet correctly at this stage is what prevents short-pours and emergency second deliveries.

For irregular shapes, break the pour into rectangular sections, calculate each separately, and add the totals — that’s how to determine cubic feet on any non-uniform slab.

Cubic Feet to Cubic Yards Conversion Formula

The core formula is simple: Cubic Yards = Cubic Feet ÷ 27. This one division answers how to calculate yards of concrete for almost any poured shape on a residential or commercial site.

If how many cubic ft in a cubic yard keeps coming up in your head, the answer is always 27 — write it on your tape measure if you have to. Figuring yards of concrete is only ever this one division away.

The table below turns the how much is a yard of concrete question into cubic footage you can measure on site.

Use this table anytime how to find yards of concrete needs a fast gut-check, or when how to measure yards in concrete on-site doesn’t match the paper takeoff. When in doubt, verify your dimensions with our free online volume calculator before finalizing the order.

How Much Is a Yard of Concrete? Full Cost Breakdown by Project Type

Now that the volume math is settled, let’s translate it into real dollars. How much is a yard of concrete across common residential project types in 2026?

Project TypeAvg. Cubic Yards NeededEstimated Cost Range
Fence post footings0.5–1 cu yd$150–$260
Sidewalk (4 in thick)1–3 cu yd$140–$400
Patio slab (4 in thick)3–6 cu yd$400–$950
Single-car driveway5–8 cu yd$650–$1,350
Garage/shed foundation8–12 cu yd$1,000–$2,100

These figures assume delivered, unpumped concrete at a standard 3000–3500 PSI mix. Add $15–$25 per yard for pump trucks on hard-to-reach pours.

How Much Is a Yard of Concrete When You Order a Short Load?

How much is a yard of concrete on a 2-yard driveway patch versus a 10-yard foundation? The per-yard rate can climb 30–40% on small orders because of flat dispatch and mobilization fees.

How much does a yard of concrete cost on a short load, exactly? Expect $200–$260 per yard all-in once short-load surcharges are added to the base rate.

How Many Cubic Yards in a Ton of Concrete? Weight-to-Volume Conversion

Ready-mix concrete weighs roughly 4,050 lbs per cubic yard, or about 2 US tons, depending on aggregate density and moisture content. This is essential for how many cubic yards in a ton calculations on truck-load scheduling.

Using metric units, how many cubic yards in a tonne works out to roughly 0.49 cubic yards per tonne (1,000 kg), since a tonne is lighter than a US ton. Flip it around and how many tonnes in a cubic yard lands near 1.85 tonnes.

Before scheduling truck loads, cross-check how much is a yard of concrete weighs against the ton capacity of your delivery truck to avoid axle-weight violations.

VolumeApprox. Weight (US Tons)Approx. Weight (Metric Tonnes)
1 cubic yard~2.0 tons~1.85 tonnes
5 cubic yards~10.0 tons~9.25 tonnes
10 cubic yards~20.0 tons~18.5 tonnes

Step-by-Step: How to Calculate Cubic Feet and Convert to Yards On Site

Once you know how much is a yard of concrete weighs and costs, the on-site math becomes straightforward.

  1. Measure length, width, and depth in feet for every section of the pour — this is how to measure cubic feet accurately before any math starts.
  2. Multiply the three dimensions together to get cubic feet per section — the standard method for how to count cubic feet on rectangular pours.
  3. Add all sections together if the slab has multiple thicknesses or steps, which answers how to figure out cubic feet on complex footprints.
  4. Divide the total cubic feet by 27 to convert into cubic yards — the universal answer to how do you calculate cubic feet into ordering units.
  5. Add a 5–10% waste factor for spillage, form leakage, and sub-grade irregularities before placing your final order.

Common Mistakes When Estimating How Much Is a Yard of Concrete You Need

The most frequent error is forgetting to convert inches to feet before multiplying — a 6-inch slab is 0.5 ft, not 6 ft, in the volume formula.

The second is skipping the waste factor entirely, which leaves crews short by half a yard on pour day. Underestimating how much is a yard of concrete you need due to skipped waste factors is the top cause of pour-day delays.

The third mistake is confusing tons with tonnes when scheduling delivery trucks against posted axle weight limits on public roads.

Frequently Asked Questions

How much is a yard of concrete on average right now?

How much is a yard of concrete generally runs $125–$180 delivered for standard residential mixes, with short loads costing more per yard due to dispatch fees.

How many cubic yards in a ton of concrete should I plan for?

Plan for roughly 0.5 cubic yards per ton, since one cubic yard weighs close to 2 US tons at standard ready-mix density.

How do I find the cubic feet of an oddly shaped footing?

Split the footing into rectangular segments, calculate each one using length × width × depth, then add the totals together before dividing by 27.

How many cubic feet are in a cubic yard exactly?

Exactly 27 cubic feet make one cubic yard, since a yard is 3 ft × 3 ft × 3 ft on every side — the number every concrete estimate is built on.

Getting the conversion right the first time is what separates a smooth pour day from an expensive callback order. Whether you’re figuring yards of concrete by hand or double-checking with our free online concrete calculator, the 27-cubic-feet rule and the pricing tables above will keep your estimate accurate and your budget intact.
