Inches to millimeters conversion?

Explanation:
The main idea is using the exact conversion factor: 1 inch equals 25.4 millimeters. Because each inch contains 25.4 millimeters, you multiply the number of inches by 25.4 to get the measurement in millimeters. The other options don’t fit: multiplying by 2.54 would convert inches to centimeters, not millimeters; multiplying by 0.305 isn’t the correct factor for this conversion; and dividing by 25.4 would convert millimeters back to inches. So multiplying by 25.4 is the correct method.
