What Is This Tool?
This tool converts volume values from fluid ounces (US), a small volume unit commonly used in cooking and packaging, to acre-feet, a large volume unit used primarily in water resource management and agriculture.
How to Use This Tool?
-
Enter the volume value in fluid ounces (US) you want to convert.
-
Select fluid ounce (US) as the source unit.
-
Choose acre-foot as the target unit.
-
Click convert to get the volume in acre-feet.
Key Features
-
Converts volume from fluid ounce (US) to acre-foot accurately based on established unit definitions.
-
Browser-based and easy to use for all skill levels.
-
Useful for translating small liquid volumes into large-scale water volume measurements.
Examples
-
16 fluid ounces (1 US cup) equals approximately 3.83610409652e-7 acre-foot.
-
128 fluid ounces (1 US liquid gallon) converts to about 3.07e-6 acre-foot.
Common Use Cases
-
Measuring ingredient volumes in US recipes and converting to large-scale water volumes.
-
Labeling beverage volumes and translating those into reservoir and lake storage calculations.
-
Planning water delivery allocations for agricultural irrigation using consistent volume units.
-
Reporting municipal or regional water supply quantities.
Tips & Best Practices
-
Use this converter to ensure consistent volume reporting between small-scale and large-scale measurements.
-
Handle results carefully since conversions lead to very small decimal numbers often presented in scientific notation.
-
Verify unit accuracy especially when integrating conversion results into environmental or hydrological studies.
Limitations
-
Fluid ounces represent very small volumes compared to acre-feet, resulting in extremely small decimal values.
-
Acre-foot is rarely used outside of water management and large-volume contexts.
-
Conversion accuracy relies on precise unit definitions and careful application in calculations.
Frequently Asked Questions
-
What is a fluid ounce (US)?
-
It is a unit of volume in the United States customary system equal to 1/128 of a US liquid gallon, exactly 29.5735295625 milliliters.
-
What does an acre-foot measure?
-
An acre-foot is the volume of water covering one acre to a depth of one foot, equaling 43,560 cubic feet, used mainly in water resources management.
-
Why convert fluid ounces to acre-feet?
-
This conversion helps translate small liquid volumes into large-scale water measurements useful for resource management and planning.
Key Terminology
-
Fluid ounce (US)
-
A US customary volume unit equal to 1/128 of a US liquid gallon, exactly 29.5735295625 milliliters, used for small liquid amounts.
