The importance of units of measurement

When we speak of the unit of measure, we refer to the value or quantity. Quantities are meaningless without specifying their unit and methods of measurement. For example, if someone wanted to buy lentils and said to the seller: “Give me the lentil” and then stopped, the single word lentil would not be enough for the seller; Because it does not carry a clear meaning of the quantity that the buyer wants.  If the seller is asked to give me a kilo of lentils, the meaning will become clearer and the buying process will become easier and easier. The International System of Units in our time includes the units of length, time, mass, current, temperature, energy, pressure, speed and other units that are familiar to us, but the ancients used other means before arriving at these methods, so that we will review in our article the most important units that were used for measurement in the past.
