How many liters equal to 1 tmc of water?

I believe TMC stands for Thousand Million Cubic Feet. So let me try to convert 1 tmc into litres. Firstly, 1 cubic feet = 30cm * 30cm *30cm = 27k cubic cm = 27k ml = 27litres 1 tmc = 1000 million cubic feet = 1000 million * 27 litres = 27000 million litres.
