Updated: 01 December 2008
Use NMILES to convert from fathoms, feet, furlongs, inches, meters, miles, nautical miles, pica, points, or yards to nautical miles.
Syntax
SELECT [westclintech].[wct].[NMILES] (
<@Length, float,>
,<@From_scale, nvarchar(4000),>)
Arguments
@Length
is any real number. @Length is an expression of type float or of a type that can be implicitly converted to float.
@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.
Return Types
float
