Concrete is the mixture of Portland cement, sand (fine aggregates), gravel (coarse aggregate), water and different types of approved admixture or ingredients. Concrete is prepared in different varieties, it is available in dry condition in premixed bagged concrete, or ready mix concrete which are prepared in batching plant by mixture machine, or it is manually mix at construction site by taking required ratio of cement, sand, gravel and water.

Modern era demanding the concreting work for various purpose such as casting of different slab, for making patio, rampe, footing, filling holes, holes post, different types of column, beam, shelter house, street, pathway, roadway, house construction, bridge formation, making heavy dams, canals and channels and in different types of construction industry.

In United States concrete are sold in bag concrete for small projects, popularly known as premix bag such as larger size of 90lb and 80 pound, medium size of 60 pound and smaller size of 40 and 50 pound. A 50 pound concrete is fast setting concrete. Premixed concrete bags are used for driveways, patios, foundations walls and footings, curbs, stairs and structural applications and also great for setting footings, pouring slabs and anchoring posts and poles.

In this article you know about formula of concrete and concrete calculator in yards, or in bags for different shape and size of slab, which will help you making a rough estimate how much concrete you will need. Here we discussed about how to figure yards of concrete and bags of concrete.

What is a cubic yard of concrete?, In United States, based on Imperial and US customary measurement system, A cubic yard of concrete is unit of measurement of volume, which is visually represented by 3 feet long by 3 feet wide by 3 feet depth, so, 1 cubic yard of concrete is 3’×3’× 3′ = 27 cubic feet, so 1 cubic yard of concrete is equivalent to 27 cubic feet.

**Concrete calculator in yards- how much concrete do you need**

A cubic yard of solid slab of concrete, which visually is 3 feet long by 3 feet wide and by 3 feet height, which is equal as 27 cubic feet when multiply length by width by height = 3’×3’×3′ = 27 cubic feet.

Concrete calculator in yards: Yards of concrete = Cubic feet of concrete × 0.037 or Cubic feet of concrete ÷ 27. Multiply the length of solid slab by the width to determine square footage. Convert the thickness of solid slab from inches to feet. Multiply the thickness in feet by the square footage to determine cubic feet. Convert cubic feet to cubic yards by multiplying by 0.037. This is yards of concrete calculation formula.

Cubic yard concrete calculator: Yards of concrete = Cubic feet of concrete × 0.037 or Cubic feet of concrete ÷ 27. To calculate how many cubic yards of concrete you will need for slab, multiply the total cubic feet needed by the 0.037 to get cubic yards of concrete.

**Concrete calculator to yards formula:-**

1) Yards of concrete = Cubic feet of concrete × 0.037

2) Yards of concrete = Cubic feet of concrete ÷ 27

How much concrete do you need?, To calculate how much concrete you will need, multiply the length by the width to determine square footage. Convert the thickness from inches to feet. Multiply the thickness in feet by the square footage to determine cubic feet. Multiply the total by 0.037 to get cubic yards. Total cubic yards is divided by yields to get number of premixed bag.

**Concrete calculator in yards formula:-**

1) Yards of concrete = Cubic feet of concrete × 0.037

2) Yards of concrete = Cubic feet of concrete ÷ 27

This concrete calculator in yards formula will use to find out how much concrete do I need?

**How to figure yards of concrete**

To figure how many cubic yards of concrete you will need for slab, multiply the total cubic feet needed by the 0.037 to get cubic yards of concrete.

To calculate yards of concrete you do the following calculation steps:-

1) Determine how thick you want the concrete

Measure the length and width that you’d like to cover

2) Multiply the length by the width to determine square footage

3) Convert the thickness from inches to feet

4) Multiply the thickness in feet by the square footage to determine cubic feet

5) Convert cubic feet to cubic yards by multiplying by 0.037.

For example:- how to figure how many yards concrete do i need for 10×10 solid slab at 4 inches thick. Ans. maths calculation:- 1) square footage of slab = 10’×10′ = 100 sq ft, 2) 4 inches thickness in feet = 4÷12 = 0.33′, 3) Cubic feet of concrete = 100 × 0.33 = 33 cubic feet, and 4) Cubic yards of concrete = 33 × 0.037 = 1.22 yards. Thus, you will need approximately 1.22 cubic yards, or 33 cubic feet, or 2.5 tons of ready mix concrete for 10 by 10 (10’×10′) slab at suggested depth of 4 inches thick.

**Formula of concrete calculation**

If you want to make rough estimate of how much concrete do you need, use the formula of concrete to find out amount of concrete, which are following:-

Concrete calculator in yards formula:- 1) Yards of concrete = Cubic feet of concrete × 0.037, or 2) Yards of concrete = Cubic feet of concrete ÷ 27

Concrete calculator to cubic feet formula:- Cubic feet of concrete = Length (in feet) × Width (in feet) × Thickness (in feet)

Concrete calculator for bags formula

Divide the total cubic yard of concrete by yields per premixed bag in yards, such as No. of premixed concrete bag = Total cubic yards ÷ yields per premixed bag in yards.

**● How much does concrete weight**

**● How much is a yard of concrete**

**● How much concrete do i need for a 10×16 slab**

**How to calculate yields of concrete premixed bag**

To determine yields of premixed concrete bag (80lb, 90lb, 60lb, 50lb, and 40lb) in yards, divide the weight of one bag of concrete in pounds by 3600 (because one yard of concrete weighs about 3600 pounds).

● 40 pound bag yields 0.011 cubic yards, yields = 40÷3600 = 0.011 yards

● 50 pound bag yields 0.0138 cubic yards, yields = 50÷3600 = 0.0138 yards

● 60 pound bag yields 0.017 cubic yards, yields = 60÷3600 = 0.017 yards

● 80 pound bag yields 0.022 cubic yards, yields = 80÷3600 = 0.022 yards

● 90 pound bag yields 0.025 cubic yards, yields = 90÷3600 = 0.025 yards.

**Concrete calculator for bags**

Concrete calculator for bags:- No. of bags of concrete = Total cubic yards ÷ Yields. To determine how many bags of concrete you will need, divide the total cubic yards needed by the yield.

Use the following yields per each bag size: 1) 40 pound bag yields 0.011 cubic yards, 2) 50 pound bag yields 0.0138 cubic yards, 3) 60 pound bag yields 0.017 cubic yards, 4) 80 pound bag yields 0.022 cubic yards, and 5) 90 pound bag yields 0.025 cubic yards.

**How to figure bags of concrete**

To figure how many bags of concrete you will need, divide the total cubic yards needed by the yield.

To determine bags of concrete, you do the following calculation steps:-

1) Determine how thick you want the concrete

Measure the length and width that you’d like to cover

2) Multiply the length by the width to determine square footage

3) Convert the thickness from inches to feet

4) Multiply the thickness in feet by the square footage to determine cubic feet

5) Convert cubic feet to cubic yards by multiplying by 0.037.

6) No. of bags of concrete = Total cubic yards÷ yields

For example:- to figure how many bags of concrete do i need for 4×4 slab at 4 inches thick. Ans. maths calculation steps:- 1) square footage of slab = 4’×4′ = 16 sq ft, 2) 4 inches thickness in feet = 4÷12 = 0.33′, 3) Cubic feet of concrete = 16 × 0.33 = 5.28 cubic feet, and 4) Cubic yards of concrete = 5.28 × 0.037 = 0.195 yards, 5) No. of 80lb bags = 0.195 ÷ 0.022 = 9 bags, or No. of 60lb bag = 0.195 ÷ 0.017 = 12 bags, or No. of 40lb bag = 0.195 ÷ 0.011 = 18 bags.

Thus, you will need approximately either Nine of 80lb (pound), or Twelve of 60lb (pound), or Eighteen of 40lb (pound) bag of concrete for 4 by 4 (4’×4′) slab at suggested depth of 4 inches thick. Thus, 0.185 cubic yards, or 5.28 cubic feet of ready mix concrete is needed for 4×4 slab at suggested depth of 4 inches thick.

**Conclusions:-**

Concrete calculator in yards: Yards of concrete = Cubic feet of concrete × 0.037 or Cubic feet of concrete ÷ 27. To calculate how many cubic yards of concrete you will need for slab, multiply the total cubic feet needed by the 0.037 to get cubic yards of concrete.
