The full form of TMC in units is: THOUSAND MILLION CUBIC FEET

What does TMC means in units - full form of TMC

 What does TMC mean?

TMC stands for Thousand Million Cubic Feet and is generally used to measure the volume of water in a reservoir. It is also used to measure the inflow and outflow of a dam.

1 TMC = 2831 crore litres = 7478711000 gallon

How do I calculate 1 TMC water?

TMC means a thousand million cubic feet

One Cubic Feet = 1ft x 1ft x 1ft = 0.3048 m x 0.3048 m x 0.3048 m = 0.02831684 m3

We know that 1-metre cube is 1000 litres

Therefore thousand million cubic feet is 0.02831684 x103 x 106m3 or 28.3164 x 109 litres. 

1 TCM = 28316846.592 m3

1 TMC = 283.168 Millions litres

How is water measured in TMC? 

Vast water bodies are measured in Thousand Million Cubin Feet or TMC with the help of scientific instruments;

  • Clepsydra – Our ancient ancestors used to use this to measure water and to tell time which is now known as water clock.
  • Irrigation – Weir is build surrounding a river or water channel that provides a controlled measure and then ultrasonic transmitters are used to measure the water. 
  • Global Measurements – Satellites are used to measure huge water bodies like the ocean; boats, ocean floor surfaces are equipped with electronics and are used to receive and transmit signals.

What is the relation between Cusec and TMC?

A Cusec is a unit meant to measure the flow of liquids, it equals to one Cubic foot per second. Hence, Cu(bic) + Sec(ond), a fusion of cubic and seconds. It is expressed as m3/s or m3/s-1. 

The amount of water to be discharged through any channel, conduit per sec in cubic feet is known as Cusec. It takes 10^9 seconds to make 1 TMC if a liquid is flowing at a speed of 1 Cusec. 

Both of these units are completely different so comparing between them is irrelevant.  

1 cubic feet per second = 28.317 liters per second

So, 1 thousand cubic feet = 28,316,846,592 liters

How can one measure the volume of a water body?

One can measure a small amount of water body by multiplying the length with its width and depth. 

For example, the volume of an Olympic sized swimming pool would be 50 meters into 25 meters into 2 meters. So the pool would hold 2,500,000 liters or 2500 cubic meters of water.
