Length was originally measured by the length of body parts, such as a finger, elbow, or stride. The Egyptian elbow, the Babylonian couscous, and the Roman foot are some of the most important measures originated in antiquity and antiquity. They also significantly influenced the development of medieval units of measurement in Europe. The most important for our area are the development of Viennese or Lower Austrian, Venetian and Paris or French units of measurement. Under their influence, domestic length measures are being developed. There was an unimaginable variety of units of measurement. Each organized human community had its own units of measurement. This has led to the use in Europe of hundreds of different elbows, feet, grips, steps. With the development of transport, industry, trade, the diversity of units of measurement has made it increasingly difficult to reach agreements between people. The idea of creating a single system of units of measurement for all peoples is an idea realized by the French Revolution, which began in the late 18th century. A committee made up of the most eminent scientists of the time made the initial units of measurement, and a new general unit of length was called the meter. The Meter Convention was signed on May 20, 1875. The Austro-Hungarian Monarchy was among the first states to co-sign the agreement. At that time, Croatia was also part of it.
