Use CONVERTSPEED to convert to and from feet per hour, feet per minute, feet per second, inches per second, kilometers per hour, knots, miles per hour, miles per minute, miles per second, meters per second, meters per minute, or meters per hour.
Syntax
SELECT [westclintech].[wct].[CONVERTSPEED] (
  <@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
@From_scale
is the description of the units @Speed is being converted from. @From_scale must be a valid value as specified in area unit representations. @From_scale must be of a data type that is implicitly convertible to varchar.
 
@To_scale
is the description of the units @Speed is being converted to. @To_scale must be a valid value as specified in area unit representations. @To_scale must be of a data type that is implicitly convertible to varchar.
 
Return Types
float
