Feet (ft) to furlongs (fur) conversion

What is the foot?

Understanding Feet

The foot is a unit of length in several different systems, including the US Customary Units and the British Imperial System. It's commonly used to measure lengths and distances in everyday contexts.

Definition and History

The foot is defined as exactly 12 inches. One international foot is equal to 0.3048 meters.

$$1 \text{ foot} = 12 \text{ inches} = 0.3048 \text{ meters}$$

Historically, the foot was based on the human foot, but its length varied across different regions and times. The standardization of the foot measurement helped bring uniformity to various applications. Check out this Wikipedia article on Foot for more history.

Notable Associations

While there isn't a specific "law" tied directly to the foot, its consistent use in various fields like construction, sports, and real estate makes it a foundational unit. No specific person is heavily associated with the unit of measurement.

Real-World Examples

• Height: People often measure their height in feet and inches (e.g., 5 feet 10 inches).
• Room Dimensions: Room sizes are frequently described in feet (e.g., 12 feet by 15 feet).
• Sports Fields: Field dimensions in sports like American football (where yards are used) are based on feet (3 feet in one yard).
• Construction: Lumber and building materials are often sold in foot increments.

Conversions

Here are some common conversions involving feet:

• Feet to Inches: Multiply the number of feet by 12.

  $$\text{Inches} = \text{Feet} \times 12$$

• Feet to Meters: Multiply the number of feet by 0.3048.

  $$\text{Meters} = \text{Feet} \times 0.3048$$

• Feet to Yards: Divide the number of feet by 3.

  $$\text{Yards} = \frac{\text{Feet}}{3}$$

What is the furlong?

The furlong (fur) is a unit of length in the imperial and US customary systems, equal to one-eighth of a mile, most commonly used today in horse racing.

Definition

One furlong equals 660 feet, or 220 yards, or 40 rods, or 10 chains.

$$1\ \text{fur} = 201.168\ \text{m}$$

Eight furlongs make one statute mile. This value uses the international foot; the US survey furlong is larger by a factor of 1200/1199.

Origin and History

The name comes from Old English "furh" (furrow) and "lang" (long), meaning the length of a furrow in a ploughed open field. In the medieval English system, a furlong was the distance a team of oxen could plough before resting, standardized as the long side of a one-acre strip (one furlong by one chain). It became a fundamental unit of the English land-measurement system.

Law and Notable Facts

The furlong survives chiefly in horse racing, where race distances are quoted in furlongs (for example, a "six-furlong sprint"). It is also preserved in the definition of the acre and the mile. The whimsical furlong–firkin–fortnight (FFF) system uses it as an example of an intentionally impractical unit of length.

Real-World Examples and Conversions

• 1 furlong = 220 yd = 660 ft = 201.168 m.
• 8 furlongs = 1 statute mile.
• 1 furlong = 10 chains = 40 rods.
• The Kentucky Derby is run over 10 furlongs (1.25 miles).
