Caliber is always the bore diameter. The encyclopedia definition is correct but backwards from common usage. Example: my old ship had a 5" 38 caliber gun meaning the bore was 5" and the barrel length was 5" x 38. As I understand the information from Hogg, the fraction 1/26 means that the length of twist was 26 times the bore diameter.
