I'm diving into a new system, and I see reports with a "Amount (converted)" field, from the Opportunity table. I'd like to look at this in SOQL, but there's no field which obviously matches; there aren't even any fields with the characters "Am" and "t". Based on the answers I've received here, it looks like this is a special reporting-only calculated column.
Given the friendly name for a calculated field ("Amount (converted)") how can I get the underlying field names and calculations? Something available through the report builder, REST, or SOAP interfaces would be great. The Schema Builder just lists the underlying names. The LayoutFieldList page lists most custom fields, but not this one.
