What are the two billing unit types from a water meter?

• A. 500 Gallons or 1000 Liters
• B. 1k Gallons or 100 Cubic Feet
• C. 1000 Liters or 200 Cubic Meters
• D. 2k Gallons or 50 Cubic Feet

Answer: (B)

The correct choice highlights the commonly used billing units for water meters, which are often measured in cubic feet and gallons. Typically, utility companies in the United States use cubic feet as a standard measurement, where one billing unit is defined as 100 cubic feet, equivalent to approximately 748 gallons. The use of 1,000 gallons is also a common practice for larger water users or in specific billing contexts, making the option that includes both 1,000 gallons and 100 cubic feet the most representative of typical billing practices.

The other options do not reflect the standard billing practices seen in many municipalities. For example, while liters and cubic meters are valid units of measurement for water usage, they are less commonly used in direct billing contexts, especially in the U.S. Similarly, other combinations of gallons and cubic feet provided in the other options do not align with widespread billing standards. The significant usage of gallons and cubic feet in formal water metering supports the accuracy of the selected answer regarding billing units.
