Mailman furlong measurement in dc

A unique question!

In Washington D.C., the mailman's furlong is a unit of measurement that is still used today, although it's not as widely known as other units like feet or yards.

A mailman's furlong is equal to 1/8 of a mile, or 220 yards. This unit of measurement originated in the 18th century, when the United States Postal Service (USPS) used it to measure the distance between mail routes.

In Washington D.C., the mailman's furlong is often used to measure the distance between streetlights, fire hydrants, and other infrastructure along the city's streets. It's also used by the District's Department of Transportation (DDOT) to measure the length of streets and sidewalks.

Here's an example of how the mailman's furlong is used in DC:

• The National Mall, which runs through the heart of Washington D.C., is approximately 1.5 mailman's furlongs long (1.5 x 220 yards = 330 yards).
• The width of a typical DC street is often measured in mailman's furlongs, with some streets being 2-3 mailman's furlongs wide (440-660 feet).

While the mailman's furlong is still used in Washington D.C., it's worth noting that it's not a standard unit of measurement in the United States. The USPS has largely phased out its use, and most other organizations and governments use more common units like feet, yards, or miles.
