Understanding the Units Involved
What is 'Tum'?
The term tum is a colloquial or regional word for inch in some languages, notably Turkish. The inch is a unit of length in the imperial system primarily used in the United States, the United Kingdom, and some other countries.
Key facts about inch (inch):
- 1 inch = 2.54 centimeters
- 1 inch = 25.4 millimeters
- Commonly used for measuring screen sizes, woodworking, and manufacturing
What is 'mm'?
Millimeter (mm) is a metric unit of length in the International System of Units (SI). It is widely used in scientific, engineering, and everyday contexts due to its precision and ease of conversion.
Key facts about millimeters:
- 1 millimeter = 0.001 meters
- 1 millimeter = 1/10th of a centimeter
- Used for precise measurements, including technical drawings, machining, and textiles

Converting 2.25 Inches to Millimeters
Conversion Formula
Since 1 inch equals 25.4 millimeters, converting inches to millimeters involves multiplying the inch value by 25.4:
Millimeters = Inches × 25.4
Calculating 2.25 Inches in Millimeters
Applying the formula:
2.25 inches × 25.4 mm/inch = 2.25 × 25.4 = 57.15 mm
Therefore, 2.25 inches equals 57.15 millimeters.
