About these units
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.
Inches
An inch (symbol: in) is a unit of length used mainly in the United States, the United Kingdom, and Canada. One inch is equal to 2.54 centimeters.
The inch has origins in ancient times, originally based on the width of a human thumb. Its current definition, established in 1959, is exactly 2.54 centimeters.
Inches are commonly used to measure smaller lengths and distances, such as screen sizes and fabric lengths. Despite the widespread adoption of the metric system, the inch remains in use in these countries.
