One U.S. bushel equals 8 U.S. dry gallons, or about 9.31 U.S. liquid gallons, depending on which “gallon” you mean.
Bushels and gallons sound like they should snap together cleanly. Then you try to price apples, measure seed, or size a storage bin and things get messy. The reason is simple: a bushel is a dry-volume unit, while “gallon” can mean a liquid gallon, a dry gallon, or an Imperial gallon.
This page clears the mix-up with plain conversions, quick math you can do on a phone, and the real-world spots where the choice of gallon changes your answer.
What A Bushel And A Gallon Measure
A bushel is a unit of capacity used for dry goods such as grain, beans, and produce sold by volume. In the United States, the standard “U.S. bushel” is defined as 2,150.42 cubic inches. That’s the anchor number behind every conversion you’ll see.
A gallon is also a unit of capacity, but the word gets used for different standards:
- U.S. liquid gallon: used for milk, gas, water, and most day-to-day “gallon” talk.
- U.S. dry gallon: used in older dry-measure tables and some agriculture contexts.
- Imperial gallon: used in the UK and some Commonwealth contexts.
Once you name the gallon type, the conversion stops being a debate and turns into arithmetic.
How Many Gallons Are In A Bushel? In Plain Numbers
Here are the two answers most people need:
- 1 U.S. bushel = 8 U.S. dry gallons (by definition, since the dry gallon is one-eighth of a bushel).
- 1 U.S. bushel = about 9.31 U.S. liquid gallons (since a liquid gallon is smaller than a dry gallon).
If your task involves produce “by the bushel” and a bucket or jug “by the gallon,” you’re usually dealing with the U.S. liquid gallon in daily life. If you’re reading a dry-measure chart, farm reference, or older extension handout, it may use the dry gallon.
Fast Conversion Formulas You Can Reuse
Pick the gallon type, then use one of these:
- Bushels → U.S. dry gallons: bushels × 8
- U.S. dry gallons → bushels: dry gallons ÷ 8
- Bushels → U.S. liquid gallons: bushels × 9.306
- U.S. liquid gallons → bushels: liquid gallons ÷ 9.306
That 9.306 factor comes from the fixed cubic-inch definitions: a U.S. bushel is 2,150.42 cubic inches and a U.S. liquid gallon is 231 cubic inches.
When The “8 Gallons” Answer Is The Right One
Use 8 when:
- You see “dry gallons,” “dry measure,” or a table that lists pecks, dry quarts, and dry pints.
- You’re matching a bushel to other dry units in U.S. customary measure.
- You need an exact conversion for math, labeling, or unit practice problems.
When The “9.31 Gallons” Answer Fits Better
Use about 9.31 when:
- You’re using everyday gallon containers or recipes that assume the U.S. liquid gallon.
- You’re estimating how many 1-gallon jugs would hold a bushel’s worth of dry volume.
- You’re planning storage using liquid-gallon markings on bins or drums.
Dry Measure Shortcuts That Keep You From Mixing Units
If you work with bushels often, it helps to anchor the whole dry-measure ladder. These are clean, fixed relationships in U.S. customary dry measure:
- 1 bushel = 4 pecks
- 1 peck = 2 dry gallons
- 1 dry gallon = 4 dry quarts
- 1 dry quart = 2 dry pints
That’s why “bushel to dry gallons” is so tidy: 4 pecks per bushel and 2 dry gallons per peck gives 8 dry gallons per bushel.
If you want the official definitions behind those values, the NIST Handbook 44 Appendix C tables of units list the standard U.S. bushel size and the related dry and liquid capacity units.
Worked Examples You Can Copy
Example 1: Bushels To Dry Gallons
You have 3.5 bushels of oats and a dry-measure chart asks for dry gallons.
3.5 × 8 = 28 dry gallons
Example 2: Bushels To U.S. Liquid Gallons
You have 2 bushels of apples and you’re using 1-gallon containers marked in U.S. liquid gallons.
2 × 9.306 = 18.612 liquid gallons
That means you’ll need 19 one-gallon containers if you want room for all of it without overflow space games.
Example 3: Liquid Gallons Back To Bushels
You measured a bin at 50 U.S. liquid gallons and want the size in bushels.
50 ÷ 9.306 = 5.37 bushels
How The Numbers Are Set
If you’ve ever seen two different “gallons per bushel” answers online, it’s usually because the writer swapped gallon types mid-sentence. You can keep it straight by starting from the fixed definitions, then converting once.
Here’s the clean chain for U.S. customary units:
- The U.S. bushel is fixed at 2,150.42 cubic inches.
- The U.S. liquid gallon is fixed at 231 cubic inches.
- Divide bushel cubic inches by liquid-gallon cubic inches: 2,150.42 ÷ 231 = 9.306 liquid gallons per bushel.
- The U.S. dry gallon is one-eighth of a bushel, so 1 bushel = 8 dry gallons on the dot.
That’s it. No special cases. When you stick to one set of definitions, every calculator and worksheet lands on the same answer.
Metric Cross-Checks When You Work In Liters
Metric labels can still play nicely with bushels. One U.S. bushel is about 35.24 liters. If your container is marked in liters, you can multiply bushels by 35.24 to estimate needed capacity, then round up for headroom.
This cross-check is handy in two spots: buying storage bins that list liters on the tag, and converting older farm notes into the units used by modern containers.
Conversion Table For Common Bushel Amounts
Use this table when you want quick numbers without pulling out a calculator. The dry-gallon column is exact. The liquid-gallon column uses the cubic-inch definition (231 in³ per U.S. liquid gallon).
| Bushels (U.S.) | U.S. Dry Gallons | U.S. Liquid Gallons (About) |
|---|---|---|
| 0.25 | 2 | 2.33 |
| 0.5 | 4 | 4.65 |
| 1 | 8 | 9.31 |
| 2 | 16 | 18.61 |
| 3 | 24 | 27.92 |
| 5 | 40 | 46.53 |
| 10 | 80 | 93.06 |
| 25 | 200 | 232.65 |
| 50 | 400 | 465.30 |
Bushel “By Weight” Versus Bushel “By Volume”
On paper, a bushel is volume. In trade, you’ll also see “bushel” used as a standard weight tied to a crop. That’s not a contradiction; it’s a shortcut used to price goods that pack differently. A bushel of wheat doesn’t weigh the same as a bushel of oats, even when the container size matches.
So if you see “56 lb per bushel” or “48 lb per bushel,” that’s a crop-specific market convention. It helps buyers and sellers speak one language. It does not change the bushel’s volume definition.
If your goal is gallons, stick to volume. If your goal is shipping weight, use the crop’s bushel-weight standard from the market or grading source tied to your region and commodity.
Imperial Bushel Notes For UK-Based Measurements
The UK’s older Imperial system defined the Imperial bushel as 8 Imperial gallons. Since the Imperial gallon is larger than the U.S. liquid gallon, the numbers won’t match U.S. gallon math.
If you’re reading a measurement table that uses Imperial units, use that system end to end. Mixing U.S. gallons with an Imperial bushel will give a wrong result.
The NIST unit tables also summarize the Imperial gallon and related capacity units, which helps when you’re converting between systems for coursework or reference reading: NIST Handbook 44 Appendix C (web version).
Storage And Container Planning With Bushels
Most storage containers you buy are labeled in liters or U.S. liquid gallons. Dry goods take up space with air gaps, so real fill level depends on the item, how you pour, and how much settling happens.
Still, the conversions help you start with a safe container size:
- Loose produce (apples, potatoes): plan extra headroom. Pieces bridge and leave gaps.
- Grain and beans: they settle more, so the filled height may drop after a shake or a drive home.
- Cracked or ground goods: pack tighter than whole kernels.
If you’re choosing containers, a simple approach works:
- Convert bushels to U.S. liquid gallons using 9.306.
- Add a buffer of 10–15% for air space and easy handling.
- Round up to the next container size you can buy.

| Cubic feet | 1.24 | Helpful for bin sizing |
| Liters | 35.24 | Metric cross-check |
Common Mistakes And How To Avoid Them
Calling Every Gallon The Same Thing
Most mix-ups come from using the word “gallon” without naming the standard. If you’re reading a chart, scan the heading for “dry” or “liquid.” If you’re using a physical container from a store, it’s almost always a U.S. liquid gallon in the U.S.
Using Bushel Weight To Do Volume Math
Bushel weights are handy for pricing and transport. They don’t convert cleanly to gallons unless you also know density and packing, which changes with moisture and how the goods sit in the container.
Rounding Too Early
Round at the end. Keep 9.306 in your calculator until the final step, then round to what your task needs. If you’re buying containers, rounding up is safer than trying to hit a tight number.
A Simple Checklist Before You Convert
- Name the system: U.S. customary or Imperial.
- Name the gallon: dry, liquid, or Imperial.
- Use one factor start to finish: 8 (dry) or 9.306 (U.S. liquid).
- For storage, add headroom and round up.
If you keep those four checks in mind, “bushel to gallons” stops being a trick question and turns into a fast, repeatable calculation you can trust.
