Block manufacturers those that use cinders material of fly ash or bottom ash, coal dust, recycle aggregator, fine particles of ash after burning of coal as an aggregate material are known as cinder blocks in the United States. Its other name concrete block is also popular.

In United States, cinder or concrete block serve as economic building material and there is a wide range of construction application for many types of Residential, Public and industrial building. Due to sturdy and long lasting building material, architect and Engineer will recommended for house construction, retaining wall, security barriers etc and this is best choice.

When you are think about starting and new projects of block masonry in external and internal or partition wall in the house, boundaries for Garden, retaining wall, block pier, foundation and columns, one of the toughest aspect is determining how many concrete blocks you will need, ordering few blocks make delay in construction for over ordering make loss of money that increases your estimate for construction, so block calculation for wall and its formula help you and better guide to find how many blocks you need.

Knowing the size of concrete block help in block wall calculation, cinder block must confirm to ASTM standard when fabricating, most commonly used, a standard size of cinder block is 16 inch long by 8 inch high by 8 inch depth, which is represented in inch as 8″×8″×16″ or in mm as 200 × 200 × 400 (depth × height× length). This is nominal size of standard cinder block, their actual size measures 3/8 inch or 10mm shorter, allowing for mortar joints, their actual size is 7 5/8″ × 7 5/8″ × 15 5/8″ or approx 190 × 190 × 390 in mm.

Regarding this, how to calculate concrete blocks, to find how many blocks you need, you do block wall calculation in following steps:-

**How many concrete blocks per 100 sq ft**

1) Calculate block wall square footage (10 ft × 10 ft = 100 square footage) :- measures length and height of block wall, suppose a block wall is 10 feet long by 10 feet high, wall sq ft = length × height = 10 ft × 10 ft = 100 square footage.

2) Calculate square footage of block (16″× 8″ = 128 sq in ÷ 144 = 0.89 sq ft):- most commonly used, a standard size of concrete block is 8″×8″×16″, block sq ft = length × height = 16″ × 8″ = 128 square inch, divide by 144 to get 128 ÷ 144 = 0.89 square footage

3) determining the number of blocks you need (100 sq ft÷ 0.89 sq ft = 112 nos blocks):- determining the number of blocks you need by dividing the wall square footage by square footage of one concrete block, such as number of blocks = wall sq ft/ block sq ft, 100/0.89 = 112 nos blocks
