1.435 m – standard gauge of railway track used by about 60% of railways in the world = 4 ft 8 1 ⁄ 2 in; 2.5 m – distance from the floor to the ceiling in an average residential house [118] 2.7 m – length of the Starr Bumble Bee II, the smallest plane; 2.77–3.44 m – wavelength of the broadcast radio FM band 87–108 MHz
For instance the same angle of 0.1 mrad will subtend 10 mm at 100 meters, 20 mm at 200 meters, etc., or similarly 0.39 inches at 100 m, 0.78 inches at 200 m, etc. Subtensions in mrad based optics are particularly useful together with target sizes and shooting distances in metric units .

The basic unit of length in the imperial and U.S. customary systems is the yard, defined as exactly 0.9144 m by international treaty in 1959. [2] [5] Common imperial units and U.S. customary units of length include: [6] thou or mil (1 ⁄ 1000 of an inch) inch (25.4 mm) foot (12 inches, 0.3048 m) yard (3 feet, 0.9144 m)
The newer 2 1 ⁄ 2 inch and 1.8 inch drive bays are specified in metric and use metric mounting screws. Newer SSDs in the M.2 form factor are measured in millimeters (e.g., "M.2 2280" is 22 mm wide by 80 mm long).
In fractions like "2 nanometers per meter" (2 n m / m = 2 nano = 2×10 −9 = 2 ppb = 2 × 0.000 000 001), so the quotients are pure-number coefficients with positive values less than or equal to 1. When parts-per notations, including the percent symbol (%), are used in regular prose (as opposed to mathematical expressions), they are still pure ...

Metric measuring spoons are available in sets, usually between four and six, typically with decilitre (100 ml), tablespoon (15 ml), teaspoon (5 ml) and millilitre measures. [citation needed] For fractional measures, there is often a line inside to indicate "half" or "a quarter", or a separate measure may be included, like 1 ⁄ 2 dl.
