TMC
TMC (thousand million cubic feet, i.e. 10⁹ ft³) is how Indian interstate water awards and dam capacities in the south are stated: Karnataka’s Cauvery release to Tamil Nadu is set in TMC, and 1 TMC = 28.317 MCM.
Symbol: TMC
Quantity: volume of stored or released water (reservoirs, river flows, allocations)
SI relation: 1 TMC = 28.316846592 MCM (exact)
Derivation: 1 TMC = 10⁹ ft³ = 28.316846592 MCM.
Exact: yes, by definition
Typical uses
- Cauvery, Krishna and Godavari tribunal awards
- Reservoir capacities in Karnataka, Tamil Nadu, Andhra Pradesh and Telangana
- Monthly water-release schedules
