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 base unit in the International System of Units (SI) is the meter, defined as "the length of the path travelled by light in vacuum during a time interval of 1 ⁄ 299792458 seconds." [ 4 ] It is approximately equal to 1.0936 yd .
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.
[1] [2] Rømer's system, which he updated in 1698, was based on the Rhine foot. Its definitions included the following: [3] the Danish mile as 24,000 Rhineland feet (i.e. 4 minutes of arc latitude) the Danish pound (pund) as 1 ⁄ 62 of the weight of a cubic Rhineland foot of water (499.7 g) the Danish ell (alen) as 2 Rhineland feet (630 mm)
[1] [2] In order to make mileposts consistent with the real mileage, every milepost beyond the equation would need to be moved. [ 3 ] For example, an equation of 7.6 back = 9.2 ahead means that the feature does not have any section between mile 7.6 and mile 9.2, and the distance between mileposts 7 and 10 is only 1.4 miles.
