What is a caliber?
The caliber belongs to the imperial and US customary family of length units, the system built on inches, feet, yards, and miles. One caliber equals 0.000254 meters, so every conversion on this page starts from that single number.
These units grew out of everyday measuring — paces, ropes, plow lengths, and body parts — so they do not line up in tens the way metric units do. That is exactly why a conversion table is useful, and you will find one for calibers below.
In writing, the caliber is usually shortened to "cl". One caliber is 0.000254 meters, and that ratio is what every figure on this page is built from.
