📏 What is Caliber and Millimeter
Caliber is a unit of length primarily used to measure the internal diameter of a tube or the external diameter of a wire or projectile. In general measurement terms, one standard caliber is defined as exactly one hundredth of an inch. A millimeter is a standard metric unit of length that makes up one thousandth of a meter. Millimeters are globally recognized and used extensively in engineering, manufacturing, and science for high precision.
