Millimeter

A millimeter (mm) is a very small unit of length in the metric system. It is commonly used to measure tiny objects or precise dimensions. One millimeter is equal to one-thousandth of a meter (1 mm = 0.001 m), and 10 millimeters make 1 centimeter. Millimeters are often used in fields like engineering, machining, and science where exact measurements are important. For example, the thickness of a credit card is about 1 mm. The symbol for millimeter is "mm", and you can find it on most rulers or measuring tools. Since it allows for high accuracy, the millimeter is ideal for measuring small parts, gaps, or details.

Long Cubit

The long cubit is an ancient unit of length that is a variation of the standard cubit, measuring from the elbow to the tip of the middle finger. The long cubit is longer than the common cubit, typically about 21 inches (approximately 53 centimeters).

It was used in ancient civilizations such as Egypt and Mesopotamia for construction, land measurement, and crafts, especially when more precision or a larger unit was needed.
