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. The Foot (ft) is commonly used in the United States and other countries for measuring medium distances. For example, the height of a table is about 3 feet, a door is usually 6.5 feet tall, and a basketball hoop is 10 feet high. It’s widely used in construction, real estate, and everyday life.
To convert between Chain (ch) and Foot (ft), use the following formulas:
1 Chain (ch) = 66 Foot (ft)
1 Foot (ft) = 0.015151515151515152 Chain (ch)
1 ch = 1 * 66 ft = 66 ft
5 ch = 5 * 66 ft = 330 ft
10 ch = 10 * 66 ft = 660 ft
20 ch = 20 * 66 ft = 1320 ft
50 ch = 50 * 66 ft = 3300 ft
100 ch = 100 * 66 ft = 6600 ft
