Correct Caliber Designation[edit]

The unit or designation of measure is Caliber. Caliber is a unit "based" on inches and/or millimeter (mm). When using the designation of caliber it is not represented directly as a measurement of inches. Refer to the definition of caliber. Caliber is expressed in hundredths or thousands of an inch depending on the number of digits. When referring to cartridges, bullets or chambers the units or designation used is caliber. This would be expressed without any leading decimal. Example: 22 LR is the 22 caliber Long Rifle cartridge. It may be approximately 0.22 inches in diameter; however, the Caliber is 22.

Leaving the decimal out of imperial specifications is intentional. It is not common language to say "Point 22 LR" or "Dot 22 LR", the common phrase is "Twenty Two LR". It is also easy to miss read or not see markings with a leading dot, thus another reason the unit of caliber is used.

This page is for specifications in caliber, This is what is used in the industry. Expressing it incorrectly as for example .45 caliber would translate a measurement in inches of 0.45/100 equaling 0.0045 inches. Another example .223 Rem. If this is a caliber unit it would translate to 0.223 thousandths (0.223/1000), which would equate to 0.000223 inches. for empirical units caliber designation never has a decimal place. Metric calibers are also often but not exclusively written and used without a decimal (i.e. Caliber 762).

The title of these pages should be updated as well as the content to avoid confusion for people learning or understanding the correct terms.

Further information on the correct way to specify values and units. Values and the units used are separated by a space. Example 7 mm is correct, 7mm is not correct. Correct case of letters (upper, lower) is also important, mm = millimeters, MM who knows that that would be. Another example (5.56 x 45 mm). Both 5.46 and 45 are in mm (millimeters), note the spacing around the x and between the number (value) and the units (mm). (talk) 21:11, 2 May 2022 (UTC)ScimernetReply[reply]
