What is an acre-foot per year?

It represents a flow rate where one acre-foot of water volume is delivered or used over the span of one year. This volume covers one acre of surface area to a depth of one foot.

Why convert acre-foot/year to gallon (US)/hour?

Converting to gallon (US)/hour allows expressing large annual water flows in smaller, hourly units useful for equipment specifications, operational monitoring, and engineering applications.

Where is gallon (US)/hour commonly used?

It is used for measuring liquid flow rates in contexts like fuel consumption of small engines, chemical dosing pumps, and HVAC systems in regions using US customary units.

What Is This Tool?

This converter transforms flow rate values from acre-foot per year, a large-scale water volume measurement over a year, to gallon (US) per hour, a smaller, hourly volumetric flow rate commonly used in non-SI contexts.

How to Use This Tool?

Enter the flow rate value in acre-foot per year.
Select acre-foot/year as the input unit and gallon (US)/hour as the output unit.
Perform the conversion to see the equivalent flow in US gallons per hour.
Use the results to assist with engineering, water management, or equipment specifications.

Key Features

Converts flow units from acre-foot/year to gallon (US)/hour accurately.
Provides a clear conversion formula and example calculations.
Suitable for water resources, agriculture, fuel consumption, and industrial applications.
Browser-based and user-friendly with easy input and output.

Examples

Convert 2 acre-foot/year to get 74.3956 gallon (US)/hour.
Convert 0.5 acre-foot/year to get 18.5989 gallon (US)/hour.

Common Use Cases

Water resource planning and reservoir management involving large volumes over a year.
Translating annual water flow data into hourly rates for process control and monitoring.
Calculating fuel burn rates for small engines and portable generators.
Specifying flow rates in small pumps and industrial HVAC systems using US gallon units.

Tips & Best Practices

Always verify units before converting to ensure accuracy in engineering reports.
Use this conversion to better understand large annual flows in more manageable hourly terms.
Consider the scale differences, as large volumes per year translate into smaller hourly flows.
Apply results to operational settings requiring US customary units for fluid measurements.

Limitations

Acre-foot/year measures large volumes over extended periods, which may not reflect short-term variations.
Gallons per hour represent smaller flow quantities, potentially leading to fractional results for very low or high flows.
Converting between these units requires care to maintain consistency in technical and regulatory contexts.

Key Terminology

Acre-foot/year [ac*ft/y]: A flow rate measuring volume equal to one acre-foot spread over one year; one acre-foot covers an acre of land one foot deep.
Gallon (US)/hour [gal (US)/h]: A volumetric flow rate indicating the number of US liquid gallons passing a point each hour, used especially in non-SI measurement contexts.
Flow rate: The volume of fluid passing a point over a period of time, expressed in various units such as acre-feet per year or gallons per hour.
