Simple Conversion Between Two Units

Use method UNIT_CONVERSION_SIMPLE to convert values from one measurement unit to another and round the result to the number of decimal places maintained in the measurement unit table T006, if necessary. Depending on the parameter ROUND_SIGN, the rounding is up ('+'), down ('-'), commercial ('X''), or no rounding (SPACE).

Note:

Make sure that both units are maintained in the measurement unit table and are not dimensionless, but have both the same dimension.
