Conversion Formula
The formula to convert inches to millimeters is very straightforward: multiply the number of inches by 25.4. This number, 25.4, is the exact length of one inch in millimeters. Because inches and millimeters measure the same dimension but different units, multiplying gives the equivalent length.
Example calculation for 0.75 inches:
- Start with 0.75 inches.
- Multiply 0.75 by 25.4 (the number of millimeters per inch).
- 0.75 × 25.4 = 19.05 mm.
- Thus, 0.75 inches equals 19.05 millimeters.
Conversion Example
Let’s convert 3 different inch values to millimeters step-by-step:
- 2 inches:
- Multiply 2 × 25.4 = 50.8 mm.
- The length in mm is 50.8.
- 5.5 inches:
- Multiply 5.5 × 25.4 = 139.7 mm.
- So, 5.5 inches equals 139.7 mm.
- 0.125 inches:
- Multiply 0.125 × 25.4 = 3.175 mm.
- Therefore, 0.125 inches is 3.175 mm.

Conversion FAQs
Why multiply inches by 25.4 to get millimeters?
The inch is defined as exactly 25.4 millimeters internationally. So, multiplying any inch value by 25.4 converts it directly into millimeters. This exact number comes from agreements on standardizing measurement units worldwide, ensuring consistency.
Can the conversion from inches to millimeters cause rounding errors?
Yes, since millimeters are smaller units, converting fractional inches may result in decimal values that need rounding. For example, 0.75 inches equals 19.05 mm, but rounding to fewer decimals can lose precision, which may matter in technical fields.
Is there a quick estimate for converting inches to mm without multiplication?
A rough estimate can be done by multiplying the inch value by 25, then adding 10% of that number. For example, for 0.75 inches: 0.75 × 25 = 18.75, then add 1.875 (10%), totaling around 20.6 mm. This is not very accurate but useful for quick guesses.
Do all countries use millimeters instead of inches?
No, the metric system, which includes millimeters, is used worldwide except for a few countries like the US, where inches remain common. Engineering and science fields often use millimeters for precision regardless of location.
How to convert inch fractions like 3/4 inch to millimeters?
Convert the fraction to a decimal first (3 ÷ 4 = 0.75), then multiply by 25.4. So, 3/4 inch = 0.75 × 25.4 = 19.05 mm. This method works for any fractional inch value.
