What is the full form of TMC?

TMC (Thousand Million Cubic Feet)

The TMC, short-form or abbreviation of Thousand Million Cubic Feet, is mainly used in water and other forms of liquid substances. One TMC ft is equivalent to about 28.317 million cubic meters.

To exemplify, 270 TMC feet of water is equal to 270 Thousand Million Cubic Feet of Water. This measurement system had been in use for hundreds of years especially during the construction of dams. Today also, it is the primary tool for water management. The term is used typically to refer very large quantity of water in a reservoir particularly for incoming water and outgoing water.

What Does TMC Stand For?

The TMC, as a mathematical system of measurement per unit of water or liquid, grew over hundreds of years. In ancient times, the TMC was used in dam construction though the name of it was in Arabic and known by another name. However, the basic purpose of TMC was the same.

The dam construction without the use of TMC just cannot even be imagined. Similarly, in the case of petroleum also, it is used as the primary unit of measurement. Inland irrigation, this measurement unit is being used. The TMC, thus, have multiple uses in measurements. Today, the TMC is the most essential unit of measurement of water and liquid-like petroleum.

A Brief History of TMC

The origin of this term perhaps took place in Egypt. Nearly 5000 years ago, in 2950 BC, the first dam known as Sadd el-Kafara came up in Egypt. At that time, a unit was needed to measure the water. The dam Sadd el-Kafara was a massive structure. It was 37 ft tall, 348 ft wide at the crest, and 265 ft at the bottom.

At that time, this basically hydrological term was used to denote a unit of water which later on came to be known in England and the USA as the TMC. The dam Sadd el-Kafara’s estimated 20 million cubic ft or 460 acre-ft (or TMC).

Conclusion

The abbreviation TMC is also used in various other fields besides water management. Such fields include irrigation in agricultural land and oil or petroleum extraction, storage, and supply. The TMC is used to convert units of Thousand Million Cubic Feet to Million Barrels of Oil units.

In the field of agriculture, the TMC is used as a term to show a rough estimate by irrigation experts. To exemplify, in the agricultural sense, 1 TMC of water is needed per year to irrigate 10,000 acres.

Frequently Asked Questions (FAQs)

When was TMC first used for measurement purposes?

In the construction of another ancient dam built around 2000 BC or 4000 years ago, the cubic feet measurement system was used. This dam is known as King Nimrod’s Dam and it was located in Mesopotamia. This historical dam using a TMC-type water measurement system in ancient times was located near Baghdad across the Tigris River.

Does TMC have any relevance in India?

The TMC as a system as it is existing now in India and all other parts of the world evolved over the centuries and was perfected by the ancient Romans in or around 100 AD, about 2000 years ago. In that year, the Ponte di San Mauro Dam was getting constructed by the Romans. They used this same TMC system to measure the water.

In India, the Central Water Commission uses TMC for reporting gross and effective storage capacities of dams in the country in the National Register of Large Dams.

What is the significance of TMC now?

Over the centuries, the TMC also played a major role in determining the construction pattern and size of a particular dam depending upon the amount of a river. Thus, the TMC became an integral part of dam construction and oil trade globally.
