# Calculate Water Consumption based on Time and Number of People

## Calculator for the water consumption displayed by the water meter. Consumption per person, consumption per period and difference can be calculated individually.

The meter reading on the water meter generally shows cubic meters (m³) in countries that use the metric system. 1 cubic meter is 1000 liters (l). The meter is usually read once a year. An average water consumption per person in a year is about 45 cubic meters, with strong fluctuations. Most of the water is used for bathing, showering and the toilet.

### Consumption per Time

Calculate how much water is used extrapolated in a certain time, if you know the average consumption in a different period of time. The results are given in cubic meters and in liters, both values are the same. The year is calculated with 365 days.

### Consumption per Person

Here you can use the total consumption to calculate how much water is consumed on average per person. Of course, it cannot be determined here whether each person actually consumes the same amount or whether one person consumes more or one less.

### Difference Consumption in a Period (in a Year)

Calculate how much water was used in the given period (usually one year). This is simply the difference between the current status and the previous status.

Please enter two values, the third will be calculated.

Here you can convert metric volume units into customary and imperial units.
