You’re standing in the grocery store aisle, staring at a plastic clamshell of blueberries. The label says one dry pint. You need two cups for that muffin recipe you promised to bring to the brunch tomorrow. Easy, right? Most of us grew up hearing "a pint's a pound the world around." We assume sixteen ounces.
Stop.
If you use that logic for one dry pint to ounces, your muffins are going to be a soggy, disappointing mess.
Here is the truth: a dry pint is not sixteen ounces. It isn't even a measurement of weight. It’s a measurement of volume, and honestly, the way we label food in the United States is kind of a disaster for anyone who actually likes precision. When you see a dry pint of cherry tomatoes or strawberries, you aren't looking at a weight measurement. You are looking at how much space those items take up in a specific container.
The Messy Reality of Dry vs. Liquid
Standard US liquid measures are straightforward. A liquid pint is 16 fluid ounces. Simple. But a dry pint is based on the US Dry Gallon, which is a completely different beast than the liquid version.
A dry pint actually equals about 33.6 cubic inches. In terms of fluid ounces? It’s roughly 18.6 fluid ounces.
Wait. Why the difference?
Historically, dry goods like grain and salt were measured differently than wine or water. It dates back to old British English systems that the US stubbornly kept while the rest of the world moved to the much more logical metric system. If you try to convert one dry pint to ounces using a standard measuring cup meant for water, you’re already off by more than two ounces of volume.
But here is where it gets really tricky. Most people aren't looking for volume; they want to know how many ounces a pint of blueberries weighs on a scale.
Weight and volume are not friends. They are barely even acquaintances.
Take a dry pint of feathers. Now take a dry pint of lead shot. Same volume. Massive difference on the scale. When you buy a "pint" of blueberries at the farmers market, you’re usually getting about 12 ounces of actual weight. If you buy a "pint" of cherry tomatoes, you might get 10 ounces. If it's a "pint" of heavy nuts, it could be way more.
The NIST Standards and Why Labels Lie
The National Institute of Standards and Technology (NIST) actually has very specific rules about this, yet we still get confused. According to NIST Handbook 133, "Checking the Net Contents of Packaged Goods," retailers have to be careful about how they use "pint" on a label.

Usually, if a fruit is small and "scopable"—think berries or sprouts—they use volume.
The problem? Air.
Gaps between the fruit matter. When you fill a dry pint container with large, lumpy strawberries, there is a ton of empty space. If you fill it with tiny wild blueberries, there is much less air. This means two different "pints" of berries can have vastly different weights.
I’ve spent years in kitchens, and I've seen bakers lose their minds over this. They see "1 pint" in a recipe and dump two 8-ounce measuring cups of berries in. Suddenly, the batter is purple soup. Why? Because the recipe writer probably meant "one dry pint container from the store," which, as we established, is roughly 12 ounces by weight, not 16.
Breaking Down the Math (The Boring but Necessary Part)
Let's look at the actual numbers for one dry pint to ounces if we are talking strictly volume:
1 US Dry Pint = 0.5 US Dry Quarts
1 US Dry Pint = 1/8 US Dry Gallon
1 US Dry Pint = 550.61 Milliliters
1 US Dry Pint ≈ 18.61 Fluid Ounces
If you are using a kitchen scale—which you absolutely should be doing—forget the word "pint" entirely.
The Grocery Store Illusion
Have you ever noticed that some berry containers are tall and narrow while others are flat and wide? They both claim to be one pint.
It's a psychological trick, or at least a logistical one.
Produce shippers prefer certain shapes because they stack better in refrigerated trucks. But for us, the consumers, it makes it impossible to eye-ball the amount. If you are trying to hit a specific nutritional goal—maybe you’re tracking macros or you're a diabetic counting carbs—relying on the "pint" label is a gamble.
I once weighed ten different "one pint" containers of raspberries from a local supermarket. The weights ranged from 9.2 ounces to 12.4 ounces. That is a massive margin of error for something that is supposedly a standardized unit of measure.

Why Does This Still Exist?
Honestly, it’s tradition. And laziness.
Switching every produce label in America to grams or even just decimal ounces would require a massive overhaul of packaging machinery. It’s easier to just keep using the old green pulp baskets that have defined "a pint" since our grandparents were kids.
Also, it sounds better. "A pint of strawberries" sounds like a bountiful summer treat. "340 grams of strawberries" sounds like a science experiment. Marketing wins every time.
Conversion Tips for Real-World Cooking
If you’re staring at a recipe right now and it’s asking for a pint of something dry, here is your cheat sheet. This isn't perfect—because physics—but it'll save your dinner.
Blueberries: One dry pint usually weighs about 12 ounces (340 grams).
Cherry Tomatoes: One dry pint usually weighs about 10-11 ounces (280-310 grams).
Strawberries: This is the wild card. Depending on size, a dry pint can be anywhere from 11 to 14 ounces.
Blackberries/Raspberries: Usually around 12 ounces, but they are fragile. If they’re crushed at the bottom, the volume drops but the weight stays the same.
Density is the enemy of the pint.
If you are measuring something like flour or sugar, never, ever use a dry pint as a reference. Use a scale. I can't stress this enough. A "pint" of flour could be 8 ounces if it's sifted or 11 ounces if it's packed down. That's the difference between a light sponge cake and a brick.
The Fluid Ounce Trap
We have to talk about the "fluid ounce" versus the "ounce."
Fluid ounces measure how much space a liquid occupies. Ounces (avoirdupois) measure how heavy something is. When people search for one dry pint to ounces, they usually don't specify which one they want.
If you want volume, it’s 18.6.
If you want weight, there is no single answer.
It’s one of those quirks of the English language that makes international students want to scream. We use the same word for two completely different physical properties.

Scientific Context: The Winchester Bushel
To understand the dry pint, you have to go back to the Winchester Bushel. This was a British measurement of volume used for corn and grain. The US adopted it in the 1800s. Interestingly, the UK actually abandoned this system in 1824 when they moved to Imperial measures, which are different again.
An Imperial pint is 20 fluid ounces.
A US liquid pint is 16 fluid ounces.
A US dry pint is roughly 18.6 fluid ounces.
If you are using a recipe from a British cookbook (looking at you, Mary Berry), and it calls for a pint, you are already using a different volume than if you use a US recipe.
Accuracy in the Modern Kitchen
If you want to be a better cook, stop measuring by volume for dry goods. Buy a digital scale. They cost fifteen bucks and will change your life.
When a recipe says "a pint of tomatoes," they are being lazy. They mean "buy one of those standard containers at the store." But if a recipe says "12 ounces of tomatoes," they are being professional. They want you to succeed.
How to Convert on the Fly
If you are stuck without a scale and you absolutely must convert one dry pint to ounces for a recipe, use the 12-ounce rule of thumb for most produce. It’s the safest middle ground.
- Check the label: Does it say "Net Wt" or just "1 PT"? If it has a weight, use that.
- The "Heaped" Factor: Dry pints in markets are often heaped over the top. This isn't a "true" pint, but it's what people expect.
- Volume displacement: If you really need to know the volume and only have a liquid measuring cup, fill it to the 18.5-ounce mark. That is your dry pint equivalent.
Beyond the Kitchen: Other Uses for Dry Pints
While we mostly deal with dry pints in the produce aisle, they occasionally pop up in gardening (seeds, fertilizer) or specialized crafts. In these cases, the 18.6 fluid ounce conversion is your gold standard.
If you're mixing soil or nutrients, being off by a few ounces usually won't kill your petunias. But in the world of high-end baking or chemistry, those "extra" 2.6 ounces (compared to a liquid pint) are a massive variable.
Actionable Steps for Your Next Recipe
Instead of guessing, take these specific actions next time you're dealing with dry measurements:
- Ignore the "Pint" on the front of the package. Flip the container over or look at the bottom of the front label for the weight in grams or ounces. That is the only number that matters for nutritional tracking or precise cooking.
- Calibrate your eyes. A dry pint is roughly two cups plus two and a quarter tablespoons. If you have to use measuring cups, don't just stop at the 2-cup line.
- Invest in a scale that toggles. Make sure your kitchen scale can switch between "fl. oz" (volume for water/milk) and "oz" (weight). Using the "fl. oz" setting for blueberries is just as bad as using a measuring cup.
- Record your findings. If you find a brand of strawberries that consistently weighs 12 ounces per pint, write it down in your favorite cookbook. It saves you the math later.
- Understand the "Pint" vs. "Pound" myth. Remember that a pint is only a pound for water. For everything else, it’s a lie.
The transition from volume-based cooking to weight-based cooking is the single biggest "level up" a home cook can take. The dry pint is a relic of an older, less precise time. It's fine for selling berries at a roadside stand, but it's a headache in a modern kitchen. Stick to the weight, and you'll never have to worry about the 18.6 vs 16 vs 12 ounce debate again.
