Understanding US Bushels to Acre-Feet Conversion
An acre-foot is the volume of water that covers one acre to a depth of one foot, equal to about 1233.5 cubic metres. It is the standard unit in US water-resource management, reservoir accounting and irrigation planning. Converting bushels to acre-feet bridges dry-commodity storage volumes and the large-scale water measures used by farm districts and hydrologists, letting analysts express grain-bin capacity in the same units as reservoir storage.
Conversion Formula
To convert US Bushels to Acre-Feet, multiply by this factor:

How to Convert US Bushels to Acre-Feet
Use the fixed volume factor between the US dry bushel and the Acre-Foot to convert in a single multiplication.
- Start with your bushel value: note the quantity in US Bushels that you want to convert.
- Apply the factor: multiply that quantity by 0.0000285688, the number of acre-foot in one bu.
- Read the result: the product is your volume in Acre-Feet; to reverse, divide by the same factor.
- Worked result: 25 US Bushels become acre-foot.

What is the US Bushel?
The US bushel is a large United States customary unit of dry volume used chiefly in agriculture to measure grain, fruit, and other bulk crops. It is the foundation of the US dry-measure system.
Definition
The US bushel (the Winchester bushel) is defined as exactly 2150.42 cubic inches.
This equals 2150.42 × 16.387064 cm³ = 35239.07 cm³. One bushel contains 4 pecks, 32 dry quarts, or 64 dry pints. It should not be confused with the imperial bushel (36.36872 L), which is about 3% larger.
Origin and History
The Winchester bushel dates to a 1696 English statute (with roots in medieval standards kept at Winchester) and was defined as a cylinder 18.5 inches in diameter and 8 inches deep, giving 2150.42 in³. The United States adopted this measure, while Great Britain replaced it with the imperial bushel in 1824.
Law and Notable Facts
Although volumetric by definition, US grain trading uses the bushel as a weight-based unit: legal "bushel weights" fix a bushel of wheat or soybeans at 60 pounds, corn and rye at 56 pounds, and oats at 32 pounds. Commodity exchanges quote grain prices per bushel on this weight basis.
Real-World Examples and Conversions
- A bushel of shelled corn weighs 56 lb (about 25.4 kg) and occupies roughly 35.24 liters of loose volume.
- 1 US bushel = 4 pecks = 8 US dry gallons = 35.2391 L.
- 1 US bushel ≈ 0.9689 imperial bushel; 1 cubic meter ≈ 28.38 US bushels.
What is the Acre-Foot?
The acre-foot is a unit of volume equal to the amount of water needed to cover one acre of land to a depth of one foot. It is the standard measure used for large-scale water resources in the United States, including reservoirs, irrigation supplies, and municipal water rights.
Definition
One acre-foot is defined as the volume of a prism with a base area of one acre (43,560 square feet) and a height of one foot, giving exactly 43,560 cubic feet.
Because the US survey foot and the international foot differ slightly, the acre-foot is fixed by its exact defining relation of 43,560 cubic feet, which equals about 1,233.48 cubic metres or 1,233,482 litres.
Origin and History
The acre-foot arose in the American West during the late 19th and early 20th centuries, as irrigation districts and water agencies needed a practical unit for measuring large volumes of stored and delivered water. It combines the acre, an old English unit of land area, with the foot of depth, making it intuitive for engineers estimating how much water a given area of reservoir or flooded field holds.
Law and Notable Facts
The acre-foot remains the legal and administrative unit for water rights, reservoir capacity, and interstate water compacts throughout the western United States. A commonly cited rule of thumb is that one acre-foot supplies roughly one to two typical American households for a year, which is why it is used to describe how many homes a reservoir can serve.
Real-World Examples and Conversions
- A single acre-foot equals about 325,851 US gallons of water.
- Lake Mead, the largest reservoir in the US, has a capacity of roughly 28.9 million acre-feet when full.
- An Olympic swimming pool holds about 2,500 cubic metres, or roughly 2 acre-feet.
- In metric terms, 1 acre-foot is approximately 1,233 cubic metres (1.23348 million litres).
Frequently Asked Questions
How many Acre-Feet are in one US Bushel?
One US Bushel equals 0.0000285688 acre-foot. Multiply any bushel figure by this factor to obtain the equivalent volume in Acre-Feet.
How do I convert Acre-Feet back to US Bushels?
Divide the number of Acre-Feet by 0.0000285688, or equivalently multiply by 35003.3, since one Acre-Foot equals 35003.3 bu.
Is the US bushel a dry or liquid measure?
The US bushel used here is a dry-volume unit of about 35.24 litres, historically defined as exactly 2150.42 cubic inches for measuring grain and produce.
Where is the US Bushels-to-Acre-Feet conversion actually used?
Converting bushels to acre-feet bridges dry-commodity storage volumes and the large-scale water measures used by farm districts and hydrologists, letting analysts express grain-bin capacity in the same units as reservoir storage.
What is 10 US Bushels in Acre-Feet?
Ten US Bushels equal 0.000285688 acre-foot, found by multiplying 10 by the conversion factor 0.0000285688.
