Description |
Quantities such as meters, grams, liters and many other sizes are standard sizes. People all around the world have agreed to name a specific length as a meter. It means that, everywhere in the world, 1 meter of thread is the same size, and it is exactly 1 meter length.At the first, these standard sizes came from traditional sizes like a span. But the size of the hand and feet of different people is different. Probably a very popular person is the best choice. For example, the length of a part of the body of the king is a yard.Or, for example, a certain weight is said to be a gram, or a certain volume is said to be a liter. But today these sizes are very precise. For example, one meter is the distance light travels in a small fraction of time. |
