The International Yard and Pound Agreement was signed by seven countries, including Australia, Canada, New Zealand, South Africa, the United Kingdom, and the United States in 1959. In this agreement, the value of the international yard was defined as exactly 0.9144 meters. This consequently made an inch exactly 0.0254 meters, or 25.4 millimeters, as there were 36 inches in a yard.
The millimeter is used to measure the lengths of very small objects such as the width of the human hair, the size of a pen tip, the size of medicine, etc.
