Syntax

SELECT [westclintech].[wct].[NMILES] (
  <@Length, float,>
 ,<@From_scale, nvarchar(4000),>)

Description

Use the scalar function NMILES to convert from fathoms, feet, furlongs, inches, meters, miles, nautical miles, pica, points or yards to nautical miles.

Arguments

@From_scale

is the description of the units for @Length. @From_scale must be a valid value as specified in length unit representations. @From_scale must be of a data type that is implicitly convertible to varchar.

@Length

is any real number. @Length is an expression of type float or of a type that can be implicitly converted to float.

Return Type

float

Remarks

The following table is a representation of the conversion of one of the length units of measure into nautical miles:

{"columns":[{"field":"column 1"},{"field":"column 2","headerClass":"ag-right-aligned-header","cellClass":"ag-right-aligned-cell"}],"rows":[{"column 1":"inches","column 2":"0.0000137149028"},{"column 1":"feet","column 2":"0.0001645788340"},{"column 1":"yards","column 2":"0.0004937365010"},{"column 1":"meters","column 2":"0.0005399568030"},{"column 1":"fathoms","column 2":"0.0009874730020"},{"column 1":"furlongs","column 2":"0.1086220300000"},{"column 1":"miles","column 2":"0.8689762420000"},{"column 1":"nautical miles","column 2":"1.0000000000000"},{"column 1":"pica","column 2":"0.0000022858171"},{"column 1":"points","column 2":"0.0000002"}]}

Conversion of meters includes all the standard prefixes with kilo representing 1,000 and yocto representing 10E-24.
