Decimal degrees (DD) is a notation for expressing latitude and longitude geographic coordinates as decimal fractions of a degree. DD are used in many geographic information systems (GIS), web mapping applications such as OpenStreetMap, and GPS devices. Decimal degrees are an alternative to using degrees-minutes-seconds notation. As with ...
Input degrees can be signed in which case the hemisphere is not required. A negative value implies a value in the western or southern hemisphere. Minutes and seconds need not be specified. If no degrees are specified then a value of zero is assumed. This template does not attempt to trap invalid values and results in this case might be undefined.
The numerical values for latitude and longitude can occur in a number of different units or formats: [2] sexagesimal degree: degrees, minutes, and seconds : 40° 26′ 46″ N 79° 58′ 56″ W; degrees and decimal minutes: 40° 26.767′ N 79° 58.933′ W; decimal degrees: +40.446 -79.982; There are 60 minutes in a degree and 60 seconds in a ...
The following converts a pressure to four output units. The precision is 1 (1 decimal place), and units are abbreviated and linked. {{convert|895|hPa|psi inHg atm mbar|1|abbr=on|lk=on}} → 895 hPa (13.0 psi; 26.4 inHg; 0.9 atm; 895.0 mbar) It is preferable to use "+" to separate output units when the first unit uses engineering notation; that ...
Signed binary angle measurement. Black is traditional degrees representation, green is a BAM as a decimal number and red is hexadecimal 32-bit BAM. In this figure the 32-bit binary integers are interpreted as signed binary fixed-point values with scaling factor 2 −31, representing fractions between −1.0 (inclusive) and +1.0 (exclusive).
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.
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.
GNU Units is a cross-platform computer program for conversion of units of quantities. It has a database of measurement units , including esoteric and historical units. This for instance allows conversion of velocities specified in furlongs per fortnight , and pressures specified in tons per acre .
