A furlong is a unit of length traditionally used in surveying and agriculture, and it is equal to 660 feet or 40 rods. On the other hand, a rod is a unit of length used in surveying and construction, and it is equivalent to 16.5 feet.
Conversion Factor: To bridge the gap between these two units, it’s essential to recognize that there are precisely 40 rods in a furlong. This conversion is expressed as:
- 1 furlong = 40 rods
Here is a table showing the conversion between furlongs and rods:

Nautical Mile Connection:
The concept of the furlong influenced the definition of the nautical mile. Historically, a furlong represented a “furrow-long,” or the length of a plowed furrow in a field, which was roughly 660 feet. This measurement influenced the nautical mile, which is slightly longer at 6,076.1155 feet or 1,852 meters.
Modern Conversion Tools:
While electronic measuring devices have largely replaced traditional units like furlongs and rods in surveying and construction, these historical units still have their place. Many conversion tools and calculators, whether in physical or digital form, offer conversions between traditional and modern units, allowing professionals to work seamlessly across measurement systems.
