A yard (symbol: yd) is a unit of length commonly used in the United States, the United Kingdom, and Canada. One yard is equal to 0.9144 meters.

The yard originated from various units used in medieval England. Its current definition is based on the international agreement of 1959, which standardized it to exactly 0.9144 meters.

Yards are often used to measure distances in sports fields, textiles, and land. Despite the global shift to the metric system, the yard remains in use in these countries.

Kilometers

A kilometer (km) is a unit of length in the International System of Units (SI), equal to 0.6214 miles. One kilometer is one thousand meters.

The prefix "kilo-" means one thousand. A kilometer is defined by 1000 times the distance light travels in 1/299,792,458 seconds. This definition may change, but a kilometer will always be one thousand meters.

Kilometers are used to measure distances on land in most countries. However, the United States and the United Kingdom still often use miles. The UK has adopted the metric system, but miles are still used on road signs.
