One of the most common is 1 inch represents 5 feet. This specifies an exact scale of 1:60. That implies that a 28 mm tall figurine represents a 1.68 m (5 ft 6 in) person – which is a reasonable number for a modern 50th percentile male (See: Human height). Another popular scale is 1/72 or 1 inch equals 6 foot which uses 20 mm, to 25 mm miniatures.
When counting dots near the boundary of the shape as 1/2, there are 69 interior dots and 20 boundary dots for an estimated area of 79, close to the actual area of 25 π ≈ 78.54. A dot planimeter is a device used in planimetrics for estimating the area of a shape, consisting of a transparent sheet containing a square grid of dots. To estimate ...
This is the scale which MOROP has defined for O scale, because it is half the size of the 1:22.5 Scale G-gauge model railways made by German manufacturers. [citation needed] 1:43.5: 7.02 mm: Model railways (0) Exact O scale of 7 mm = 1 foot. 1:43: 7.088 mm: Die-cast cars: Still the most popular scale for die-cast cars worldwide, metric or ...
The apparent triangles formed from the figures are 13 units wide and 5 units tall, so it appears that the area should be S = 13×5 / 2 = 32.5 units. However, the blue triangle has a ratio of 5:2 (=2.5), while the red triangle has the ratio 8:3 (≈2.667), so the apparent combined hypotenuse in each figure is actually bent. With the bent ...
1:144 scale is a scale used for some scale models such as micro/mini armor. 1:144 means that the dimensions of the model are 1/144 (0.00694) the dimensions of the original life-sized object; this equates to a scale of 1/2 inch per 6 feet of original dimension. For instance, an airplane 30 feet (9.14 m) in length would be a mere 2.5 inches (63.5 ...
The micrometre (SI symbol: μm) is a unit of length in the metric system equal to 10 −6 metres ( 1 / 1 000 000 m = 0. 000 001 m). To help compare different orders of magnitude , this section lists some items with lengths between 10 −6 and 10 −5 m (between 1 and 10 micrometers , or μm).

1:32 is a useful scale for scratch modelling or railways. As well as standard gauge gauge 1 using 45 mm / 1.772 in track, narrow gauge modellers use 0 gauge (32 mm / 1.26 in) track for 42", 1m and 36" prototype gauges. Also H0/00 track at 16.5 mm is used to represent models of 20 in / 508 mm gauge railways.
