Micrometers (µm) measure cells (human cell = ~10–30 µm), bacteria (1–5 µm), and microelectronics. Pollen grains are ~15–100 µm wide. 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.
To convert between Micrometer (µm) and Thou (Mil) (mil), use the following formulas:
1 Micrometer (µm) = 0.03937007874015748 Thou (Mil) (mil)
1 Thou (Mil) (mil) = 25.400000000000002 Micrometer (µm)
1 µm = 1 * 0.03937007874015748 mil = 0.03937007874015748 mil
10 µm = 10 * 0.03937007874015748 mil = 0.39370078740157477 mil
50 µm = 50 * 0.03937007874015748 mil = 1.968503937007874 mil
100 µm = 100 * 0.03937007874015748 mil = 3.937007874015748 mil
500 µm = 500 * 0.03937007874015748 mil = 19.68503937007874 mil
