The earliest known measurement system has been created in the 4th and 3rd millennium BC in ancient Egypt, Mesopotamia, Indus Valley, and Elam (far west and southwest of modern-day Iran). According to Babylonian and Egyptian records and the Hebrew Bible the forearm, and or finger was used to measure the length, while the periods of the sun, moon, and other heavenly bodies were used to measure time. The initial procedure for measuring the container's capacity was to fill the containers with plant seeds and the seeds were then counted to measure the container volume. After the weighing tools were invented the seeds and stones served as standards.
The common units such as inch, foot, and yard were evolved from ancient Egypt, Greeks, and Romans. The ancient Greeks and Romans inherited the foot from the Egyptians. The Roman foot was divided into 12 unicae and 16 digits.
The Roman mile which is equal to 5000 feet or 1480 [m] was introduced in England during the occupation. The mile unit was later changed by Queen Elizabeth I from 5000 to 5280 feet (1609 m) or 8 furlongs. $$1 \left[\mathrm{furlong}\right] = 40 \left[\mathrm{rod}\right] = 5.5 \left[\mathrm{yards}\right] = 201.168 \left[\mathrm{m}\right]$$
The origin of yard unit is still today, unknown. There are two theories about its origin. Some believe that the yard unit originated from the double cubit, while others believe that it originated from the cubic measure. The earliest version of the yard was divided into 2,4,8, and 16 parts which are called half-yard, b, finger, and nail.
In Britain, the larger mass units that were used was stone, quarter, hundredweight, and ton. Today only the stone unti remain in customary use for measuring the personal body weight. Today \(1 \left[\mathrm{stone}\right] = 14 \left[\mathrm{pounds}\right] = 6.35 \left[\mathrm{kg}\right]\), however the earlier version of stone unit \(1 \left[\mathrm{stone}\right] = 16 \left[\mathrm{pounds}\right] = 7.25 \left[\mathrm{kg}\right]\). The other units were multiplies of 2, 8, and 160 times the stone, or 28, 112, 2240 pounds which is equal to 12.7, 50.8 and 1016 [kg], repsectively.
In ancient times there were many civilizations developed their systems for measuring length, area, and capacity. These ancient civilizations are:
Units of length
The earliest known units of length are Egyptian and Mesopotamian cubit that were used in the 3rd millennium BC. In ancient India the units of length that were used included the dhanus (Dhanush (bow)), the krosa (cry, (cow-call)), and yojana (stage). In ancient Egypt and Mesopotamia, the unit "cubit" was the length of the forearm from the elbow to the tip of the middle finger.The common units such as inch, foot, and yard were evolved from ancient Egypt, Greeks, and Romans.

Units of mass
The earliest and the smallest unit of mass was grain which is equal in today's units of mass, to 64.79891 \(\left[\mathrm{mg}\right]\). The early unit was a grain of wheat or barleycorn used to weigh precious metals such as silver or gold. The unit pound was derived from the mina unit that was used in ancient civilizations. The smaller unit of mina was shekle and the larger unit was talent. These units were not constant since the value varied from plate to place. In Babylonians and Sumerians, one talent was equal to 60 minas while one minas was equal to 60 shekels. The Roman talent was equal to 100 libra (pound) that was smaller in magnitude than the mina. In England and the U.S., the troy pound was used for monetary purposes and was divided into 12 ounces. One troy pound is equal to approximately 373.2 \(\left[\mathrm{g}\right]\). The carat is used for measuring gemstones that had their origin in the carbo seed and later standardized at 1/144 ounce and then 0.2 gram.In Britain, the larger mass units that were used was stone, quarter, hundredweight, and ton.

Units of time and angle
The ancient Babylonians were responsible for the division of the circle in 360 degrees and the day into hours, minutes and seconds due to the sexagesimal system of numbers (numeral system with sixty as the base). There were of course many other systems of measurement that divided the day differently.In ancient times there were many civilizations developed their systems for measuring length, area, and capacity.
