So you’re staring at a recipe or some manual and suddenly hit a wall. How many mL in a quart? Yeah, me too. I learned the hard way that quarts aren’t all created equal. Like, are we talking U.S. quarts or the British ones? Because, spoiler alert—they’re not the same.
Anyway, lemme spill the tea (or the broth): A quart can be a tricky little devil depending on where you are. In the U.S., one quart is just under a liter. But cross the pond, and it gets even more confusing. Here’s where it gets good:
1 U.S. liquid quart = 946.353 mL (close enough to 950, if you ask me)
1 Imperial (British) quart = 1,136.52 mL
Yeah, that’s a solid 200 mL difference—like adding or losing half a cup of coffee. And if you’re like me, who once confused these during a camping trip, well… let’s just say my chili was extra watery.
What’s a Quart Anyway?
Quick flashback. The word “quart” comes from Latin quartus, meaning “a fourth.” It was literally a quarter of a gallon. Makes sense, right? But then different countries ran with it their own way, and voila—now you have the “U.S. quart” and the “Imperial quart.”
Here’s the kicker: I’ve lost count how many times I’ve used the wrong quart because of this. The first time was at Pete’s Hardware on 5th Ave. Bought a measuring jug labeled “quart” for my garden, only to find out it was Imperial-sized. My tomato fertilizer ended up more like soup. Soggy, sad tomatoes. RIP Gary (my herb garden).
The Quick-and-Dirty Table You’ll Actually Use
I once tried to memorize all these decimals. Bad idea. So here’s what I actually scribbled down on a crumpled napkin that survived three kitchen spills:
| Quart Type | Milliliters (mL) |
| U.S. Liquid Quart | 946.353 mL |
| U.S. Dry Quart | 1,101.22 mL |
| Imperial (U.K.) Quart | 1,136.52 mL |
Got that? Good. I say how many mL in a quart every time I cook now like it’s a magic spell.
Mental Hacks: How to Remember “How Many mL in a Quart”
Let’s be honest, decimals are a nightmare. Here are some tricks that helped me (and might help y’all too):
- Round to 950 mL: That’s the U.S. liquid quart. I say it’s “almost a liter, but not quite.”
- Think “4 cups in a quart”: Since 1 cup ≈ 237 mL, 4 cups ≈ 946 mL. Easy peasy.
- Use water bottles: A standard water bottle is 500 mL, so a quart is like two water bottles (minus a gulp). Helpful for camping when you don’t have measuring tools.
Bonus: That Walmart rosemary smell on a summer afternoon once reminded me that even the weirdest sensory memories can help retain weird facts.
Wait, Which Quart Are We Talking About?
Seriously, I once mixed this up ordering drinks at a British pub. Asked for a quart of cider. Got a jug way bigger than I imagined. They laughed. I laughed. We bonded over my ignorance.
Here’s a breakdown of quarts you might bump into:
- U.S. Liquid Quart (the most common): ~946 mL
- U.S. Dry Quart (used for dry goods, like flour): ~1,101 mL (Yeah, bigger)
- Imperial Quart (U.K.): ~1,136 mL
See? Their/there mix-ups? Guilty as charged. But this one’s easy to mess up too.
How to Convert Like a Pro (Without a Calculator)
Alright, if you’re still reading, here’s a cheat sheet for conversions that I once wrote on paper (coffee spilled on it, so bear with me):
- To get mL from quarts (U.S.):
mL = quarts × 946.353 - To get quarts from mL (U.S.):
quarts = mL ÷ 946.353
For the British imperial quart, just swap out 946 for 1,136.52.
Side note: I still Google it sometimes, okay? You need nitrogen-rich soil—wait, no, was it potassium? Let me Google that again…
Real-Life Moments That Made Me Love Knowing This
Picture this: I’m helping my neighbor Tina, who swears by her kale patch curing her Zoom fatigue (and honestly, I’m starting to believe her). She wanted to convert a UK recipe for salad dressing. I had to explain how many mL in a quart because she was about to dump nearly 200 mL less dressing than needed. Big salad emergency averted.
Another time, in a chemistry lab, a professor mentioned how NASA once lost a $125 million probe because of a unit conversion mix-up. True story. If you don’t want your Martian rover to suffer, knowing this stuff is a lifesaver.
Why Bother Knowing “How Many mL in a Quart”?
Sure, you can just ask Siri or check Google every time. But let me tell you, knowing this saved me from:
- Cooking disasters (watery soups, anyone?)
- Buying wrong-sized containers at Pete’s Hardware
- Awkward travel moments ordering drinks or groceries abroad
Plus, it’s a fun party fact. I mean, how many people casually know this? If you want to sound wicked smart, just drop:
“Did you know the quart’s origin is Latin for a fourth, but it varies so much that the British quart is about 20% bigger than the American one?”
Boom. Mind blown.
Some Nerdy Nuggets To Impress (Or Annoy) Your Friends
- Fun fact: Victorians believed talking to ferns prevented madness. I talk to my begonias just in case.
- The cracked watering can from Pete’s Hardware that survived my overwatering phase? Priceless.
- As noted on page 42 of the out-of-print Garden Mishaps & Miracles (1998), the confusion between volume units has led to some historic baking disasters. My sourdough starter dying faster than my patience in that book’s intro.
Final Bits — Because You Asked: How Many mL in a Quart?
Let me say it one last time, like a mantra:
1 U.S. liquid quart = 946.353 mL
1 U.S. dry quart = 1,101.22 mL
1 Imperial quart = 1,136.52 mL
And if you forget all that, just remember:
“A quart is roughly a liter, give or take a few sips.”
Fast forward past three failed chili attempts, and I promise you’ll nail it too.
