- Multiply 5 × 25.4
- 5 × 25.4 = 127 mm
- So, 5 inches equals 127 mm.
- Convert 12.3 inches to mm:
- 12.3 × 25.4 = 312.42 mm
- Step 1: Multiply the decimal number 12.3 with 25.4
- Step 2: Result is 312.42 mm
- Therefore, 12.3 inches equals 312.42 millimeters.
- Convert 0.75 inches to mm:
- 0.75 × 25.4 = 19.05 mm
- Multiply the fraction by 25.4
- Resulting in 19.05 millimeters.
- Convert 20 inches to mm:
- 20 × 25.4 = 508 mm
- Multiply 20 by the conversion factor
- Result is 508 millimeters.

Conversion Definitions
Inches: A unit of length in the imperial measurement system, one inch equals 1/12 of a foot or exactly 2.54 centimeters. It is used mainly in the United States, Canada, and the UK for measuring small distances or lengths, such as screen sizes, height, or fabric length.
Millimeters (mm): A metric unit of length equal to one thousandth of a meter. Millimeters are used worldwide in science, engineering, and everyday measurements where precision is required. They are smaller than centimeters and often used for small object dimensions.
Conversion FAQs
Can I convert inches to millimeters by dividing?
No, dividing won’t work for converting inches to millimeters. Since 1 inch equals 25.4 millimeters, you must multiply the inch value by 25.4 to get millimeters. Dividing would give incorrect results and confuse the unit scale.
Is 10.75 inches the same as 273 mm exactly?
Yes, 10.75 inches equals exactly 273.05 millimeters when multiplied by 25.4. The tiny difference of 0.05 mm is due to decimal rounding, but practically, 273 mm is a very close approximation.
Why is 1 inch defined as 25.4 millimeters?
The inch is defined as exactly 25.4 mm by international agreement to unify imperial and metric measurements. This exact value replaced earlier approximations to provide consistent conversions worldwide, especially in manufacturing and engineering.
Can I convert 10.75 inches to mm without using a calculator?
Yes, you can approximate by multiplying 10.75 by 25, then add a bit more for the 0.4 part. For example, 10.75 × 25 = 268.75, plus 10.75 × 0.4 = 4.3, total about 273.05 mm. It’s a rough method but close enough for basic needs.
Are millimeters smaller than inches?
Yes, millimeters are smaller than inches. One inch equals 25.4 millimeters, so it takes over 25 millimeters to make one inch. Millimeters provide finer measurement units, useful for precision compared to the larger inch scale.
