How To calculate how many 450x225 tiles there are in a m2

To calculate how many 450x225 tiles there are in 1 square metre, use this method:

Step 1:

Multiply the width and height of one tile. So in this case the area of one tile is: 450mm x 225mm =
0.10125 m2
or 45cm x 22.5cm =
0.10125 m2

Step 2:

Divide 1m by the area of one tile to give you the number of 450mm x 225mm tiles in a m2: 1m / 0.10125 = 9.9 Tiles per m2

Step 3:

NOTE: It is only possible to buy whole tiles, therefore you need to round up 9.9 tiles to 10 tiles

9.9 tiles =
10 tiles required
