**140 Millimeters to Inches equals 5.5118 in.**

To convert 140 millimeters (mm) to inches, we use the conversion factor that 1 inch is equal to 25.4 millimeters. The calculation involves dividing the length in millimeters by the conversion factor. This process allows us to determine the equivalent length in inches since the two units measure the same physical quantity, length, but utilize different scales. The formula applied is:

\([ \text{Length in inches} = \frac{\text{Length in millimeters}}{25.4} ]\)

Applying this formula to convert 140 mm into inches, we get:

\([ \text{Length in inches} = \frac{140}{25.4} ]\)

\([ \text{Length in inches} \approx 5.51 ]\)

Thus, 140 mm is approximately equal to 5.51 inches. This calculation entails dividing the millimeter value by the value of one inch in millimeters. The result gives us a straightforward conversion based on the proportionality between the metric system (which uses units such as millimeters) and the imperial system (which uses inches). It's a simple division that yields the equivalence between these two units of measure, providing a clear understanding of the length or distance when converted from the metric system (widely used around the world) to the imperial system (primarily used in the United States).
