What is a cubic meter of water?

How much is a cubic meter of water

A cubic meter (m3) of water is the equivalent to 1000 liters of water.

1m3 = 1000 liters

The cubic meter is the measurement unit used by the water suppliers to calculate the water cost based on an agreed cost per cubic meter. 

Most of the houses have a water meter which measures the amount of water being consumed.

If you are able to understand the value displayed by the meter you can calculate the water cost by yourself.

As an example, the water meter below is showing a water consumption of 1,214 cubic meters (m3) which is the equivalent to 1214 liters.

1,214 cubic meters x 2 euro per cubic meter = 2,5 euro (approx.)

Note tat for this calculation we have used the average water cost per cubic meter in Germany, which is 2 euro. Depending on where you live, the water cost can be higher or lower.

Reduce your water consumption

If you are interested on further increasing your knowledge and learning how to reduce your water consumption and save money, have a look to the ideas that we share in this video:

Water conservation - Save and conserve water

– Water conservation can be defined as the decision and the act of using less water –

– Water conservation both benefit you and the environment – 

The act of saving and conserving water does benefit you because you will be paying less on your water bills. 

And it also does benefit the environment because conserving water prevents any unnecessary waste of natural resources.

Now, at individual level it may not look worth to try to save a few litres or gallons here or there. 

Still, every little counts and if hundreds or thousands of us do save a little every time, it will make an important contribution towards conserving our natural resources.


For example, if 9000 households would manage to save as little as 5 litres of water per day:

  • Collectively, we would be saving over 16,000,000 litres of water per year!
  • Collectively, assuming a cost of 2 euro per cubic meter of water, we would be saving nearly 33,000 euro per year.
It is clear that small water savings do really count when looking into the bigger picture.
