Syntax
SELECT [westclintech].[wct].[MSEC] (
<@Speed, float,>
,<@From_scale, nvarchar(4000),>
,<@To_scale, nvarchar(4000),>)
Arguments
@Speed
is any real number. @Speed is an expression of type float or of a type that can be implicitly converted to float.

is the description of the units for @Speed. @From_scale must be a valid value as specified in speed unit representations. @From_scale must be of a data type that is implicitly convertible to varchar.
@To_scale
is the description of the metric units that @Speed is to be converted into. @To_scale must be a valid value as specified in speed unit representations. In addition to meters per second, @To_scale can be decimeters per second, centimeters per second, millimeters per second, micrometers per second, nanometers per second, picometers per second, femtometers per second, attometers per second, zeptometers per second, yoctometers per second, decameters per second, hectometers per second, or kilometers per second .@To_scale must be of a data type that is implicitly convertible to varchar.
