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 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 Thou (Mil) (mil) and Millimeter (mm), use the following formulas:
1 Thou (Mil) (mil) = 0.0254 Millimeter (mm)
1 Millimeter (mm) = 39.37007874015748 Thou (Mil) (mil)
1 mil = 1 * 0.0254 mm = 0.0254 mm
5 mil = 5 * 0.0254 mm = 0.127 mm
10 mil = 10 * 0.0254 mm = 0.254 mm
50 mil = 50 * 0.0254 mm = 1.27 mm
100 mil = 100 * 0.0254 mm = 2.54 mm
500 mil = 500 * 0.0254 mm = 12.7 mm
1000 mil = 1000 * 0.0254 mm = 25.4 mm
