About these units
Millimeters
A millimeter (mm) is a unit of length in the International System of Units (SI). One millimeter is equivalent to 0.001 meters or approximately 0.03937 inches.
The millimeter is defined as one-thousandth of a meter, making it a precise measurement for small distances.
Millimeters are used worldwide to measure length and distance in various fields, including engineering, manufacturing, and everyday life. Many industries, especially those requiring high precision, have adopted the millimeter as a standard unit of measurement for small lengths.
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.
