To convert 12 mm to inches, you need to know the conversion factor between millimeters and inches. 1 inch is equal to 25.4 millimeters. Therefore, to convert millimeters to inches, you can use the formula: inches = millimeters รท 25.4. Using this formula, let's convert 12 mm to inches.

$$[ 12 \, \text{mm} * \left( \frac{1 \, \text{inch}}{25.4\, \text{mm}} \right) = 0.47244 \, \text{inches} ]$$

Thus, 12 mm is equal to approximately 0.4724 inches when rounded to four decimal places. This calculation was done by understanding the relationship between millimeters and inches, where every inch equals 25.4 millimeters. By dividing the number of millimeters by this conversion factor, we find the equivalent measurement in inches. This simple division allows us to convert measurements from the metric system, which is used widely around the world for its simplicity and standardization, to the imperial system, still in use in a few countries including the United States.
