Understanding US Fluid Drams to US Dry Pints Conversion
The US fluid dram (fl-dr) is a small liquid measure of about 3.70 milliliters from the apothecaries' system. The US dry pint (pnt-dry) is a dry-volume unit of about 550.6 milliliters, used for berries, produce, and other loose goods sold by volume. Converting between them relates a fine liquid dose to a common farmers-market measure across two different traditions.

What is the US Fluid Dram?
The US fluid dram (also spelled fluid drachm) is a small United States customary unit of liquid volume, historically important in pharmacy and medicine for dispensing doses of liquid medication.
Definition
The US fluid dram is defined as one eighth of a US fluid ounce, or equivalently 60 minims.
Since the US fluid ounce is exactly 29.5735295625 mL, a fluid dram equals 3.6966912 mL. The UK/imperial fluid drachm is slightly larger at about 3.5516 mL (1/8 of the imperial fluid ounce).
Origin and History
"Dram" derives from the Greek drachma, an ancient coin and weight. The apothecaries' system split the fluid ounce into 8 fluid drams and each dram into 60 minims, giving pharmacists a fine graduation for compounding and measuring liquid remedies.
Law and Notable Facts
The fluid dram is a legal US customary unit but is now largely obsolete in clinical practice, superseded by milliliters. Its legacy survives in the term "dram" for a small pour of whisky and in the traditional 8-dram, 1-fluid-ounce medicine bottle.
Real-World Examples and Conversions
- A single US fluid dram is about 3.70 mL, roughly three-quarters of a metric teaspoon.
- 8 US fluid drams equal 1 US fluid ounce (29.5735 mL).
- 1 US fluid dram = 60 minims ≈ 0.75 teaspoon; 1 mL ≈ 0.2705 US fluid dram.
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.
Frequently Asked Questions
How many US dry pints are in a US fluid dram?
One US fluid dram equals about 0.006713805 dry pints, a small fraction because a dry pint is much larger.
How many fluid drams fill one US dry pint?
It takes about 148.9 fluid drams to make a single US dry pint.
Why is a dry pint bigger than a liquid pint?
The dry pint (about 550.6 mL) is defined from the dry-measure bushel line, while the US liquid pint (about 473.2 mL) comes from the liquid gallon, so the dry pint is roughly 16 percent larger.
What is 150 fluid drams in dry pints?
Multiply 150 by 0.006713805 to get about 1.007 dry pints.
Where do dry pints show up?
Dry pints are common at markets for selling blueberries, cherry tomatoes, and other produce by volume rather than weight.
