Last, multiply the original expression of the physical value by the fraction, called a conversion factor, to obtain the same physical value expressed in terms of a different unit. Note: since valid conversion factors are dimensionless and have a numerical value of one , multiplying any physical quantity by such a conversion factor (which is 1 ...
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.
Digital camera sensor sizes are measured in an archaic manner indicating inverse fractions of an inch representing the diameter of an equivalent vidicon tube. For example, a 1 ⁄ 1.6 in sensor is larger than a 1 ⁄ 2.5 in sensor. However, lenses are marked in terms of focal length in millimeters (e.g., average natural human field of view is a ...
The first metric Melbourne Cup was raced in November 1972. An early change was the metrication of horse racing. This was facilitated because the furlong (one-eighth of a mile) is close to 200 m. Therefore, the Melbourne Cup was changed from 2 mi to 3,200 m, a reduction of 19 m or about 0.6%. The first metric Melbourne Cup was raced in November ...
A simple fraction (also known as a common fraction or vulgar fraction) [n 1] is a rational number written as a/b or , where a and b are both integers. [9] As with other fractions, the denominator (b) cannot be zero. Examples include 1 / 2 , − 8 / 5 , −8 / 5 , and 8 / −5 .
A simple arithmetic calculator was first included with Windows 1.0. [5]In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression.
Metric, but some non-metric units are used for specific areas: rural land – alqueire; cattle weight – arroba; screen sizes – polegada (inch); tyre pressure – libra-força por polegada quadrada, but referred by its English abbreviation: psi. Peru: Peruvian (variants of Spanish) Metric, but inches (pulgadas) are used for screen sizes and ...
A metric prefix is a unit prefix that precedes a basic unit of measure to indicate a multiple or submultiple of the unit. All metric prefixes used today are decadic . Each prefix has a unique symbol that is prepended to any unit symbol.
