Understanding US Dry Pints to Acre-Feet Conversion
The US Dry Pint (pnt-dry) is the US dry pint, one-eighth of a US dry gallon (about 0.550610 litre or 33.6003 cubic inches), the box size sold for berries and small produce. The Acre-Foot (acre-foot) is the acre-foot, the volume of water covering one acre to a depth of one foot (43,560 cubic feet, about 1,233.48 cubic metres), the standard unit in US water-resource and irrigation management. This conversion spans an enormous range, translating a berry-box pint into the acre-foot unit used for reservoir and irrigation water accounting.

What is the US Dry Pint?
The US dry pint is a United States customary unit of volume for dry goods such as fruit, grain, and vegetables. It is larger than the US liquid pint and is part of the bushel-based dry measure system.
Definition
The US dry pint is defined as one half of a US dry quart, equal to exactly 33.6003125 cubic inches.
Since the US bushel is exactly 2150.42 in³, a dry pint equals 2150.42 ÷ 64 = 33.6003125 in³ = 550.610471 cm³. This is roughly 16% larger than the US liquid pint (0.473176 L).
Origin and History
Like all US dry measures, the dry pint derives from the English Winchester bushel used in colonial America. The US kept this pre-1824 standard while Britain moved to the imperial system, producing the lasting split between US and imperial pints.
Law and Notable Facts
The dry pint is a recognized US customary unit defined through the international inch. It survives most visibly at grocery stores and farmers' markets, where berries and cherry tomatoes are commonly sold by the "pint" basket, a nominal dry-pint container.
Real-World Examples and Conversions
- A dry pint of blueberries holds about 0.55 liter, typically around 12 oz of fruit by weight.
- 2 US dry pints equal 1 US dry quart (1.10122 L).
- 1 liter equals about 1.8162 US dry pints.
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 Dry Pint?
One US Dry Pint equals 4.46387 x 10⁻⁷ Acre-Feet, found by multiplying by the fixed factor 4.46387 x 10⁻⁷.
