- Result is 1270 millimeters
Conversion Example
- Convert 12 inches to millimeters:
- Start with 12 inches
- Multiply by 25.4 (12 × 25.4)
- Calculate: 12 × 25.4 = 304.8
- So, 12 inches equals 304.8 millimeters
- Convert 7.5 inches to millimeters:
- Take 7.5 inches
- Multiply by 25.4 (7.5 × 25.4)
- Calculate: 7.5 × 25.4 = 190.5
- Therefore, 7.5 inches equals 190.5 millimeters
- Convert 100 inches to millimeters:
- Start with 100 inches
- Multiply by 25.4 (100 × 25.4)
- Calculate: 100 × 25.4 = 2540
- 100 inches equals 2540 millimeters
- Convert 0.25 inches to millimeters:
- Take 0.25 inches
- Multiply by 25.4 (0.25 × 25.4)
- Calculate: 0.25 × 25.4 = 6.35
- So, 0.25 inches equals 6.35 millimeters

Conversion Definitions
Inches: An inch is a unit of length in the imperial and US customary systems, equal to 1/12 of a foot or exactly 25.4 millimeters. It is used in the United States and some other countries for measuring small distances and sizes, particularly in construction and manufacturing.
Millimeters (mm): A millimeter is a metric unit of length equal to one thousandth of a meter. It is widely used for precise measurements in engineering, machining, and science. Millimeters provide a finer scale compared to inches, helpful in detailed work.
Conversion FAQs
Why is 1 inch exactly 25.4 millimeters?
The inch was internationally standardized in 1959 by agreement between English-speaking countries. They defined 1 inch as exactly 25.4 millimeters to unify measurement systems and avoid discrepancies that arose from older, slightly different inch definitions.
Can I convert inches to millimeters by just multiplying by 2.54?
Multiplying by 2.54 converts inches to centimeters, not millimeters. Since there are 10 millimeters in one centimeter, to get millimeters directly you multiply inches by 25.4, which is 2.54 × 10.
Are inch-to-millimeter conversions always precise?
Yes, because the inch is defined exactly as 25.4 millimeters, the conversion is precise. However, rounding during calculations or display can cause small approximations in results.
Why use millimeters instead of inches?
Millimeters offer a smaller unit scale, making them better suited for precise measurements and technical fields like engineering. Inches are more common in everyday US use but lack the decimal divisibility of metric units.
How to convert fractions of an inch to millimeters?
First convert the fraction to a decimal (for example, 1/2 inch = 0.5 inch), then multiply by 25.4. This gives the equivalent length in millimeters accurately.
