Measurement Accuracy

When is a part 2.5mm pin Spacing, and when is it 2.54mm Spacing listed as 2.5mm?

Example: 2222

According to the Raspberry Pi DXF file, it is clearly 2.54 mm pin spacing on the 2x20 connector.

As a PCB Designer, it is absolutely vital the measurement be 100% accurate with the answer carried out to the appropriate # of Decimal Places.
