So, you’re in the kitchen, staring at your measuring cups and wondering, “Okay, how many cups in half gallon?” Been there, done that. I once measured a half gallon of milk by pouring and praying. Spoiler: it wasn’t pretty.
Anyway, here’s the skinny: half gallon equals 8 cups. Yup, eight. Not seven, not nine, but a solid eight. Easy, right?
What Even Is a Gallon, Anyway?
Alright, before we dive deeper into how many cups in half gallon, let’s clear up gallons because… surprise! There’s more than one kind.
In the US, a gallon is 16 cups. Simple enough. But if you’re over in the UK, their gallon is a whole different beast—bigger, no less. So when you’re Googling “how many cups in half gallon” make sure you’re thinking US gallons. Otherwise, you might end up with some seriously weird measuring.
Also, cups in the US are 8 fluid ounces, which is a handy tidbit to stash away for later.

If you’re like me, you might still want to double-check with your measuring cup—because spill. Spills happen.

Measuring Half Gallon Like a Pro (Or Not)
Got a giant measuring cup? Perfect. Fill it to 8 cups — done.
No giant cup? No problem. Measure 2 quarts (because half gallon = 2 quarts). Or, if you’re feeling really old school, pour 4 pints (yeah, that’s also half a gallon).
Pro tip: The cracked measuring jug I bought from Pete’s Hardware on 5th Ave has survived every kitchen meltdown I’ve had, including that time I almost flooded my kitchen. It’s a trooper.
Fun Fact Break: Why Gallons & Cups?
Why does anyone use gallons when cups are way easier? Because some recipes are for big groups. Like, making chili for a potluck versus a single serving.
And gallons come from how liquids were packaged historically — milk bottles, water jugs — so it stuck. Also, some states like to be different.
Half Gallon Weight? Does That Matter?
It does if you’re into baking or want to know how much your milk weighs when you’re lugging it up the stairs.
Water’s easy: half gallon weighs about 4.17 pounds. Milk’s a bit heavier — roughly 4.3 pounds for the same volume.
