Convert 1.5 Inches to Millimeters (in to mm) with our conversion calculator.

1.5 Inches to Millimeters equals 38.1000 mm.

To convert inches to millimeters, we use the conversion factor that 1 inch is equal to 25.4 millimeters. Knowing this, to convert 1.5 inches to millimeters, the calculation is as follows:

\([1.5\, \text{inches} \times 25.4\, \frac{\text{mm}}{\text{inch}} = 38.1\, \text{mm}.]\)

This conversion relies on a fixed mathematical relationship where each inch corresponds to exactly 25.4 millimeters. By multiplying the length value in inches by this conversion factor, we get the equivalent length in millimeters. This is a simple linear transformation where the inch value is the input, 25.4 is the multiplier (or scale factor) representing how many millimeters are in one inch, and the product is the output in millimeters. The process involves straightforward arithmetic multiplication, easily done with a calculator or manually for those comfortable with multiplying decimal values.
