By default, the output value is rounded to adjust its precision to match that of the input. An input such as 1234 is interpreted as 1234 ± 0.5, while 1200 is interpreted as 1200 ± 50, and the output value is displayed accordingly, taking into account the scale factor used in the conversion.
Input with fractions: 1 + 1 ⁄ 2 inches (38.1 mm) The number to convert can be written in fractions. Both / (keyboard slash) ... 1.0 mm 3 (6.1 × 10 −5 cu in) ...
Subdivisions of an inch are typically written using dyadic fractions with odd number numerators; for example, two and three-eighths of an inch would be written as 2 + 3 / 8 ″ and not as 2.375″ nor as 2 + 6 / 16 ″. However, for engineering purposes fractions are commonly given to three or four places of decimals and have been ...
The depth is generally 16 inches (410 mm) (for use in residential fireplaces) but can be anything from 12 to 32 inches (300 to 810 mm). This results in a volume of 32 to 85 cubic feet (0.91 to 2.41 m 3). In the United States, several states only allow wood to be sold by the cord or fractions of a cord, to avoid confusion among consumers. [4] [5]
Drill bit sizes are written as irreducible fractions. So, instead of 78/64 inch, or 1 14/64 inch, the size is noted as 1 7/32 inch. Below is a chart providing the decimal-fraction equivalents that are most relevant to fractional-inch drill bit sizes (that is, 0 to 1 by 64ths).
In the following quote, an "apertal ratio" of "1 ⁄ 24" is calculated as the ratio of 6 inches (150 mm) to 1 ⁄ 4 inch (6.4 mm), corresponding to an f /24 f-stop: In every lens there is, corresponding to a given apertal ratio (that is, the ratio of the diameter of the stop to the focal length), a certain distance of a near object from it ...
If using the metric unit meters for distance and the imperial unit inches for target size, one has to multiply by a factor of 25.4, since one inch is defined as 25.4 millimeters. distance in meters = target in inches angle in mrad × 25.4 {\displaystyle {\text{distance in meters}}={\frac {\text{target in inches}}{\text{angle in mrad}}}\times 25.4}
0.435 mm A value in decimal degrees to a precision of 4 decimal places is precise to 11.1 metres (36 ft) at the equator . A value in decimal degrees to 5 decimal places is precise to 1.11 metres (3 ft 8 in) at the equator.
