What is Centimeters?

Centimeters (cm) are a unit of length in the metric system. They are commonly used for everyday measurements and technical applications alike. Understanding their relationship to other units and their practical applications is key.

Centimeter Definition and Formation

A centimeter is defined as one-hundredth of a meter. The prefix "centi-" indicates a factor of $10⁻²$. Therefore:

$1 \text{ cm} = \frac{1}{100} \text{ m} = 0.01 \text{ m}$

The metric system, including centimeters, originated in France during the French Revolution in the late 18th century, aiming for a standardized and rational system of measurement.

Relationship to Other Units

Here's how centimeters relate to some other common units of length:

• Millimeter (mm): 1 cm = 10 mm
• Meter (m): 1 m = 100 cm
• Inch (in): 1 in = 2.54 cm (exactly)
• Foot (ft): 1 ft = 30.48 cm (exactly)

Common Uses and Examples

Centimeters are used in a variety of contexts:

• Clothing: Measuring body dimensions (e.g., waist, inseam) for clothing sizes.
• Construction: Measuring lengths of building materials, room dimensions.
• Electronics: Specifying the size of electronic components or device dimensions.
• Maps: Indicating scale on maps, representing distances on the ground. For example, a map might have a scale where 1 cm represents 1 kilometer.
• Everyday objects: The width of a standard pen is approximately 1 cm. A credit card is roughly 8.5 cm long and 5.4 cm wide.
• Medical field: Wound measurement and monitoring of growth.

Notable Associations

While no specific law is named after the centimeter, its importance stems from its place within the widely adopted metric system. The metric system's adoption has been a key factor in scientific progress, enabling standardized communication and calculations. The International System of Units (SI), which defines the meter and therefore the centimeter, is maintained by the International Bureau of Weights and Measures (BIPM).

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).
