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]}

Mettur Dam capacity: 93.4 Tmcft

Conversion

1 tmcft is equivalent to:

• 1,000,000,000 cubic feet (28,000,000 m³) (approx)
• 2,831 crore litres
• 2.831684660 Giga Litres
• 2831684.660 cubic metres
• 22,956.841139 acre feet
• 6.228835459×10⁹ imperial gallons

Alternatively, 35.32 tmcft = 1 cubic kilometer (km³) is the standard unit used by the Central Water Commission of the 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 4,000 ha (10,000 acres).^[3]
