## Overview (en)

The water usage calculator estimates consumption from a flow rate in liters per minute, minutes per use, uses per day and number of days, then converts the total to cubic meters and applies your price per cubic meter. It works for showers, taps, hoses or any fixture with a known flow rate. Days can range up to 36,600.

## Questions (en)

### How much water does a 10-minute shower use?

With the default flow rate of 8 liters per minute, a 10-minute shower uses 80 liters. Two showers a day for 30 days add up to 4800 liters, or 4.8 cubic meters.

### Can I use gallons in the water usage calculator?

The fields expect liters per minute and a price per cubic meter. To work from gallons, convert first: one US gallon is about 3.785 liters. Results are reported in liters, cubic meters and cost.

### How is the water cost calculated?

Total liters are divided by 1000 to get cubic meters, then multiplied by your price per cubic meter. Sewer charges and fixed fees are not added separately, so include them in the rate if your bill combines them.
