The number of concrete blocks in a metre will depend on the type of concrete block being used.Concrete blocks come in different sizes in different countries and each has variations in width, height and thickness based on the standard module size, such as 1/2 or 3/4 variants of each dimension.Note that each block has an actual size and a nominalsize that accounts for a typical mortar joint. Usually the nominal size is a round number giving easier calculations and construction dimensions. (The nominal depth is not usually the depth of the individual wall, as there is no mortar layer needed.)The standard modules for some countries are:UKBlock dimensions 440mm Long × 215mm High × 190mm Deep (~17 1/3" L × 8 7/15" H × 7 1/2" D)Nominal dimensions 450mm Long x 225mm High x 200mm Deep (~17 5/7" L × 8 6/7" H × 7 7/8" D)Number per lineal metre: 2.22Number per square metre: 9.88Also available as a standard module:Block dimensions: 390mm Long x 190mm High x 190mm DeepNominal dimensions: 400mm Long x 200mm High x 200mm DeepNumber per lineal metre: 2.5Number per square metre: 12.5USABlock dimensions: 390mm Long × 190mm High × 190mm Deep(~15 5/8" L × 7 5/8" H × 7 5/8" D)Nominal dimensions: 400mm Long x 200mm High x 200mm Deep (~16"L × 8"H × 8"D)Number per lineal metre: 2.5Number per square metre: 12.5Australia and New ZealandBlock dimensions: 390mm Long x 190mm High x 190mm DeepNominal dimensions: 400mm Long x 200mm High x 200mm DeepNumber per lineal metre: 2.5Number per square metre: 12.5
60 blocks make a metre square
What sort of blocks? Childrens' building blocks? If so, how big is each block?
For blocks that are 450mm x 225mm , you will need 9.88 blocks per square metre.
The number of concrete hollow blocks in 1 square meter depends on the size of the blocks. For example, if the blocks are 20cm x 20cm x 40cm, which is a common size, you would need 25 blocks to cover 1 square meter (assuming no gaps or mortar). This calculation is based on the fact that each block covers 0.04 square meters (0.2m x 0.2m) of surface area. It's important to consider the dimensions of the blocks and the desired layout to determine the exact number needed.
