Primarily used in horse racing (UK/US). 1 furlong = 660 feet = 1/8 mile. 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 Furlong (fur) and Chain (ch), use the following formulas:
1 Furlong (fur) = 10 Chain (ch)
1 Chain (ch) = 0.1 Furlong (fur)
1 fur = 1 * 10 ch = 10 ch
5 fur = 5 * 10 ch = 50 ch
8 fur = 8 * 10 ch = 80 ch
| Furlong (fur) | Chain (ch) |
|---|---|
| 1 fur | 10 ch |
| 5 fur | 50 ch |
| 10 fur | 100 ch |
