The hectometer (hm) is useful for measuring sports tracks (1 lap = 4 hm), urban blocks (~1–2 hm long), or vineyard rows. Road signs in some European countries use hectometers for minor distance markers. 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 Hectometer (hm) and Chain (ch), use the following formulas:
1 Hectometer (hm) = 4.970969537898672 Chain (ch)
1 Chain (ch) = 0.201168 Hectometer (hm)
1 hm = 1 * 4.970969537898672 ch = 4.970969537898672 ch
2 hm = 2 * 4.970969537898672 ch = 9.941939075797343 ch
5 hm = 5 * 4.970969537898672 ch = 24.854847689493358 ch
10 hm = 10 * 4.970969537898672 ch = 49.709695378986716 ch
