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. 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 Rod (rd) and Thou (Mil) (mil), use the following formulas:
1 Rod (rd) = 198000 Thou (Mil) (mil)
1 Thou (Mil) (mil) = 0.000005050505050505051 Rod (rd)
1 rd = 1 * 198000 mil = 198000 mil
2 rd = 2 * 198000 mil = 396000 mil
5 rd = 5 * 198000 mil = 990000 mil
10 rd = 10 * 198000 mil = 1980000 mil
20 rd = 20 * 198000 mil = 3960000 mil
50 rd = 50 * 198000 mil = 9900000 mil
| Rod (rd) | Thou (Mil) (mil) |
|---|---|
| 1 rd | 198000 mil |
| 2 rd | 396000 mil |
| 5 rd | 990000 mil |
| 10 rd | 1980000 mil |
| 20 rd | 3960000 mil |
| 50 rd | 9900000 mil |
