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 decameter (dam) is used to measure medium-scale distances like the length of a tennis court (~2.3 dam) or a cricket pitch (~2.0 dam). It’s also practical for land surveying and agricultural plots (e.g., a small field might be 10 dam × 20 dam).
To convert between Rod (rd) and Decameter (dam), use the following formulas:
1 Rod (rd) = 0.50292 Decameter (dam)
1 Decameter (dam) = 1.9883878151594685 Rod (rd)
1 rd = 1 * 0.50292 dam = 0.50292 dam
2 rd = 2 * 0.50292 dam = 1.00584 dam
5 rd = 5 * 0.50292 dam = 2.5146 dam
10 rd = 10 * 0.50292 dam = 5.0292 dam
20 rd = 20 * 0.50292 dam = 10.0584 dam
50 rd = 50 * 0.50292 dam = 25.146 dam
