The Inch (in) is commonly used in the United States and other countries for measuring small to medium objects. For example, a smartphone screen is around 6 inches, a standard ruler is 12 inches, and a doorway height is about 80 inches. It's widely used in carpentry, display sizes, and construction. The Millimeter (mm) is perfect for very small measurements like the thickness of a credit card (0.76 mm), the diameter of a pencil lead (0.5-0.7 mm), or the size of small hardware components. Commonly used in engineering, jewelry design and manufacturing.
To convert between Inch (in) and Millimeter (mm), use the following formulas:
1 Inch (in) = 25.4 Millimeter (mm)
1 Millimeter (mm) = 0.03937007874015748 Inch (in)
1 in = 1 * 25.4 mm = 25.4 mm
2 in = 2 * 25.4 mm = 50.8 mm
5 in = 5 * 25.4 mm = 127 mm
10 in = 10 * 25.4 mm = 254 mm
20 in = 20 * 25.4 mm = 508 mm
50 in = 50 * 25.4 mm = 1270 mm
100 in = 100 * 25.4 mm = 2540 mm
