A standard metric (concrete) block is 190 mm wide, 390 mm long, and 190 mm high, which allows for 10 mm mortar joints in between bricks, giving a standard unit size of 200 mm square by 400 mm long. [3] A standard metric brick is 90 by 57 by 190 mm; with 10 mm of mortar, that produces a standard unit of 100 mm x 200 mm. [3]
In England, the length and width of the common brick remained fairly constant from 1625 when the size was regulated by statute at 9 x 4 + 1 ⁄ 2 x 3 inches [45] (but see brick tax), but the depth has varied from about two inches (51 mm) or smaller in earlier times to about 2 + 1 ⁄ 2 inches (64 mm) more recently.
Working dimensions is the size of a manufactured brick. It is also called the nominal size of a brick. Brick size may be slightly different due to shrinkage or distortion due to firing, etc. An example of a co-ordinating metric commonly used for bricks in the UK is as follows: [4] [5] [6] Bricks of dimensions 215 mm × 102.5 mm × 65 mm;
Equivalent VIII, 1966, 120 Firebricks, 5 by 27 by 90 + 1 ⁄ 4 inches (130 mm × 690 mm × 2,290 mm), occasionally referred to as The Bricks, is the last of a series of minimalist sculptures by Carl Andre. The sculpture consists of 120 fire bricks, arranged in two layers, in a six-by-ten rectangle. [1]
Conversion of units is the conversion of the unit of measurement in which a quantity is expressed, typically through a multiplicative conversion factor that changes the unit without changing the quantity. This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property.

The millimetre (SI symbol: mm) is a unit of length in the metric system equal to 10 −3 metres ( 1 / 1 000 m = 0.001 m). To help compare different orders of magnitude, this section lists lengths between 10 −3 m and 10 −2 m (1 mm and 1 cm). 1.0 mm – 1/1,000 of a meter; 1.0 mm – 0.03937 inches or 5/127 (exactly)
