Which data type is used for money?
Unlike the DECIMAL data type, the MONEY data type is always treated as a fixed-point decimal number. The database server defines the data type MONEY(p) as DECIMAL(p,2). If the precision and scale are not specified, the database server defines a MONEY column as DECIMAL(16,2).

CAST is also less powerful and less flexible than CONVERT. On the other hand, CONVERT allows more flexibility and is the preferred function to use for data, time values, traditional numbers, and money signifiers. CONVERT is also useful in formatting the data’s format.
How to convert currency in SQL?
