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 Rod (or pole/perch) was historically used in land surveying and agriculture. Measuring exactly 16.5 feet, rods were commonly used to define property boundaries. A standard American football field is 320 rods long (including end zones). This unit still appears in some property deeds and agricultural measurements.
To convert between Thou (Mil) (mil) and Rod (rd), use the following formulas:
1 Thou (Mil) (mil) = 0.000005050505050505051 Rod (rd)
1 Rod (rd) = 198000 Thou (Mil) (mil)
1 mil = 1 * 0.000005050505050505051 rd = 0.000005050505050505051 rd
5 mil = 5 * 0.000005050505050505051 rd = 0.000025252525252525253 rd
10 mil = 10 * 0.000005050505050505051 rd = 0.000050505050505050505 rd
50 mil = 50 * 0.000005050505050505051 rd = 0.0002525252525252525 rd
100 mil = 100 * 0.000005050505050505051 rd = 0.000505050505050505 rd
500 mil = 500 * 0.000005050505050505051 rd = 0.0025252525252525255 rd
1000 mil = 1000 * 0.000005050505050505051 rd = 0.005050505050505051 rd
