Calculator for concrete bags | Calculate concrete bags needed | how many concrete bags do i need | how many concrete bags in a yard.

In US, concrete are sold in bag concrete for small projects, popularly known as premix bag. Premix bag of concrete are available in many different size and weight, larger size of bagged concrete are available in 90lb (pound) and 80lb (pound) concrete, medium size available in 60lb (pound) concrete and smaller size is 50lb (pound) and 40lb (pound) concrete.

Premixed bag of concrete is the mixture of Portland cement, sand (fine aggregates), gravel (coarse aggregate), and different types of approved admixture or ingredients. 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 “calculator for concrete bags”, which will help you making a rough estimate how many bags of concrete do i need. Here we discussed about how to calculate how many bags of concrete do i need.

Quikrete or Sakrete 80lb (pounds) bags concrete Mix can be used for building or repairing foundation walls, sidewalks, curbs, steps and ramps and for setting posts. This concrete mix is designed for pouring concrete 2″ to 4″ thick or more and is easy to use by simply adding water.

50lb (pounds) bags of concrete mix is ideal for both structural and non structural application for 2 inch thick or more, 50lb bag of Concrete Mix can be used for building or repairing foundation walls, fence post, sidewalks, curbs, steps and ramps and for setting posts and others concrete structure like, footing, slab & beam.

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.

**Calculator for concrete bags**

To calculate number of bags of concrete do you need, divide the total yards of concrete needed by bags yields in yards. To determine how many bags of concrete you will need for one yard, divide the one cubic yards needed by the yield.

**Calculator for concrete bags**:- Formula for No. of Concrete bags = Cubic yards ÷ Bags 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: 40lb bag yields 0.011 cubic yards, 60lb bag yields 0.017 cubic yards, 80lb bag yields 0.022 cubic yards, 50lb bag yields 0.0138 cubic yards, and 90lb bag yields 0.025 cubic yards.

**Formula for No. of bags of concrete do you need = total cubic yards ÷ bags yields in yards**

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).

**Formula for calculating yields of premixed bag = Weight of one bag of concrete ÷ 3600**

● 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.

**Calculate concrete bags needed**

Calculate concrete bags needed:- To calculate 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: 40 pound bag yields 0.011 cubic yards, 60 pound bag yields 0.017 cubic yards, 80 pound bag yields 0.022 cubic yards, 50 pound bag yields 0.0138 cubic yards, and 90 pound bag yields 0.025 cubic yards.

To figure out how many number of bags of concrete i need, multiply length by width, and then by thickness in feet. Multiply the resulting number by 0.037 to find cubic yards. Then divide the total yards of concrete needed by bags yields in yards. Formula for No. of bags of concrete you need= Total cubic yards ÷ Yields per bag in yards.

**Steps to calculate concrete bags needed are following:-**

1) Square footage of concrete slab = Length × Width

2) Thickness in feet = Thickness in inches ÷ 12

3) Cubic feet of concrete = Square footage × Thickness in feet

4) Cubic yards of concrete = Cubic feet of concrete × 0.037

5) No. of bags of concrete you need = Total yards of concrete ÷ Yields.

**For example:-** To calculate how many bags of concrete do i need for 10×10 slab at 4 inches thick. Ans. maths calculation: 1) Square footage = 10’×10′ = 100 sq ft, 2) 4″ in feet = 4/12 = 0.33′, 3) Total cubic feet = 100×0.33 = 33 cubic feet, 4) Total cubic yards = 33×0.037 = 1.22 yards, 5) No. of 80lb bags = 1.22 ÷ 0.022 = 56 bags, or No. of 60lb bags = 1.22 ÷ 0.017 = 72 bags, or No. of 40lb bags = 1.22 ÷ 0.011 = 110 bags.

You will need approximately Fifty six of 80lb (pounds), or Seventy two of 60lb, or One hundred ten of 40lb bags of concrete for 10 by 10 solid slab at suggested depth of 4 inches thick.

● How much concrete is in a cubic yard

● How many bags of concrete do i need for 10 cubic feet

● How much does a bag of concrete cover (80 lb, 60 lb, 40 lb)

**How many concrete bags in a yard**

There are approximately either Sixty of 60 lb, or Forty of 90 lb, or Forty five of 80 lb, or Seventy two of 50 lb, or Ninety of 40 lb concrete bags in a yard. Thus, the amount of bags it takes to make one yard of concrete is either 90 of 40lb, or 45 of 80lb, or 60 of 60lb bags of concrete.

**How many bags of concrete do you need**

Formula for No. of bags of concrete you need = Total cubic yards ÷ Yields. To calculate number of bags of concrete do you need, divide the total yards of concrete needed by bags yields in yards. For example: You will need approximately either 180 of 40lb, or 90 of 80lb, or 120 of 60lb, or 144 of 50lb, or 80 of 90lb bags of concrete for 2 yards.

**Conclusions:-**

Calculator for concrete bags:- Formula for No. of Concrete bags = Cubic yards ÷ Bags yields. To determine how many bags of concrete you will need, divide the total cubic yards needed by the yield.
