Mettur Dam capacity: 93.4 Tmcft

Tmcft, (Tmc ft), (TMC), (tmc), is the abbreviation of thousand million cubic feet (1,000,000,000 = 109 = 1 billion), commonly used in India in reference to volume of water in a reservoir [1] or river flow. [2] [ failed verification ]



1 tmcft is equivalent to:

Alternatively, 35.32 tmcft = 1 cubic kilometer (km3) is the standard unit used by Central Water Commission of Government of India for reporting gross and effective storage capacities of dams in India in National Register of Large Dams (NRLD). The amount of water that can be discharged through a conduit per second in a cubic foot is described as a cusec.

In agriculture, a rough estimate by irrigation experts is that 1 TMC water is needed each year to irrigate 10,000 acres. [3]
