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. 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.
To convert between Millimeter (mm) and Inch (in), use the following formulas:
1 Millimeter (mm) = 0.03937007874015748 Inch (in)
1 Inch (in) = 25.4 Millimeter (mm)
1 mm = 1 * 0.03937007874015748 in = 0.03937007874015748 in
8 mm = 8 * 0.03937007874015748 in = 0.31496062992125984 in
30 mm = 30 * 0.03937007874015748 in = 1.1811023622047243 in
90 mm = 90 * 0.03937007874015748 in = 3.543307086614173 in
120 mm = 120 * 0.03937007874015748 in = 4.724409448818897 in
245 mm = 245 * 0.03937007874015748 in = 9.645669291338583 in
559 mm = 559 * 0.03937007874015748 in = 22.00787401574803 in
