The Thou (also called Mil) is essential in precision engineering and manufacturing. For context, a standard sheet of paper is about 100 thou thick, while human hair measures approximately 20-30 thou in diameter. This unit is critical in machining tolerances, PCB design, and automotive engineering where exact measurements are crucial. 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 Thou (Mil) (mil) and Inch (in), use the following formulas:
1 Thou (Mil) (mil) = 0.001 Inch (in)
1 Inch (in) = 999.9999999999999 Thou (Mil) (mil)
1 mil = 1 * 0.001 in = 0.001 in
5 mil = 5 * 0.001 in = 0.005 in
10 mil = 10 * 0.001 in = 0.01 in
50 mil = 50 * 0.001 in = 0.05 in
100 mil = 100 * 0.001 in = 0.1 in
500 mil = 500 * 0.001 in = 0.5 in
1000 mil = 1000 * 0.001 in = 1 in
