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 Chain (Gunter's chain) was fundamental in surveying the American frontier. Measuring 66 feet (4 rods), it's the length of a cricket pitch. Ten square chains make an acre. Modern surveyors still reference chains in legal descriptions, and the unit remains visible in rural road layouts across the US.
To convert between Thou (Mil) (mil) and Chain (ch), use the following formulas:
1 Thou (Mil) (mil) = 0.0000012626262626262627 Chain (ch)
1 Chain (ch) = 792000 Thou (Mil) (mil)
1 mil = 1 * 0.0000012626262626262627 ch = 0.0000012626262626262627 ch
5 mil = 5 * 0.0000012626262626262627 ch = 0.000006313131313131313 ch
10 mil = 10 * 0.0000012626262626262627 ch = 0.000012626262626262626 ch
50 mil = 50 * 0.0000012626262626262627 ch = 0.00006313131313131313 ch
100 mil = 100 * 0.0000012626262626262627 ch = 0.00012626262626262626 ch
500 mil = 500 * 0.0000012626262626262627 ch = 0.0006313131313131314 ch
1000 mil = 1000 * 0.0000012626262626262627 ch = 0.0012626262626262627 ch
