A yard (yd) is a unit of length in the imperial and US customary systems of measurement.
A yard is equal to 3 feet (ft) or 36 inches.
The history of the yard is traditionally linked to English monarchs. According to folklore, King Henry I of England (reigned 1100-1135) decreed that a yard should be the distance from the tip of his nose to the end of his outstretched thumb.
While this story is popular, the unit's origins likely date back to the Anglo-Saxons and were later standardized by various royal decrees and physical "yardsticks."
In 1959, an international agreement defined the yard as precisely 0.9144 meters.
This global standardization of the unit ensures consistent conversions between the imperial and metric systems.
To summarize the key yard conversions:
Although most of the world uses the metric system, the yard remains essential in some places—especially the United States and the United Kingdom.
It's the standard unit in American and Canadian football, commonly used in the textile industry to sell fabric, and often used to measure distances on golf courses.
A kilometer (km) is a unit of length in the metric system, equal to 1,000 meters.
The plural form is kilometers.
The term "kilometer" is composed of two parts: the metric unit "meter" and the Greek prefix "kilo," which comes from the word "khilioi," meaning "thousand."
Thus, a kilometer translates to one thousand meters.
This concept is a fundamental aspect of the decimal-based metric system, established in France during the 1790s. The logical, prefix-based nature of the metric system simplifies conversions, which is a key reason for its widespread adoption.
The kilometer is the official unit of measurement for geographical distance in the vast majority of countries worldwide.
Only a few nations still primarily use the mile for road signage and navigation, most notably:
For international travel, science, and sporting events like marathons and the Olympics, the kilometer is the universally accepted standard.
To understand how far a kilometer is, consider these real-world examples:
This consistent unit of measurement makes it easy to compare everything from everyday travel to distances in space.
