Given a numeric quantity (src_quantity) specified with a given unit (src_unit) and scale (src_scale), convert that quantity to a specified unit and scale.
| EDCS_SC_SUCCESS | and *dest_quantity_ptr is set to the result of the specified conversion, if valid parameters were passed in. |
| EDCS_SC_NULL_REQUIRED_PARAMETER | and *dest_quantity_ptr is left unchanged, if dest_quantity_ptr was NULL. |
| EDCS_SC_INVALID_INPUT_UNIT | and *dest_quantity_ptr is set to zero (0), if src_unit is not a valid EU code. |
| EDCS_SC_INVALID_OUTPUT_UNIT | and *dest_quantity_ptr is set to zero (0), if dest_unit is not a valid EU code. |
| EDCS_SC_INVALID_INPUT_UNIT_SCALE | and *dest_quantity_ptr is set to zero (0), if src_scale is not a valid ES code. |
| EDCS_SC_INVALID_OUTPUT_UNIT_SCALE | and *dest_quantity_ptr is set to zero (0), if dest_scale is not a valid ES code. |
| EDCS_SC_UNITS_NOT_EQUIVALENT | and *dest_quantity_ptr is set to zero (0), if src_unit and dest_unit do not belong to the same EQ. |
