Conversion FAQs
Why is the conversion factor 25.4 when converting inches to millimeters?
The number 25.4 comes from an international agreement that sets one inch equal to exactly 25.4 millimeters. This value replaced earlier definitions based on physical objects, providing a standard fixed length to maintain consistency worldwide.
Can I convert inches to millimeters without a calculator?
Yes, you can estimate by multiplying the inch value by 25 and then adding a little more for the 0.4 part. For example, for 1 inch, 25 mm plus 0.4 mm equals 25.4 mm. For more precision, a calculator is preferred but rough conversions can be done mentally.
