Which is the correct conversion for 1 furlong in chains?

• A. 5 chains
• B. 8 chains
• C. 12 chains
• D. 10 chains

Answer: (D)

Understanding how furlongs relate to chains comes from knowing the lengths of each unit. A mile is 5,280 feet, and there are eight furlongs per mile, so a furlong is 660 feet. A chain is 66 feet. Dividing 660 by 66 gives 10, so one furlong equals 10 chains. You can also see this in yards: a chain is 22 yards and a furlong is 220 yards; 220 ÷ 22 = 10. Therefore the correct conversion is 10 chains. The other options correspond to quantities that are shorter or longer than a furlong (for example, 5 chains is 330 feet, which is half a furlong; 8 chains is 528 feet, which is 1/10 mile; 12 chains is 792 feet).
