Hey everyone, it’s your boy back again with another one of my little experiments. Today’s adventure? Figuring out just how many cups of sugar are packed into one of those hefty 4-pound bags. Yeah, you heard that right. I was in the kitchen, staring down a recipe that called for cups of sugar, and all I had was this big ol’ bag. So, I rolled up my sleeves and got to work.
First things first, I needed to know the basics. Like, how much does a cup of sugar even weigh? After a bit of digging around, I found out that a cup of the granulated stuff is roughly 7 ounces. Okay, cool. But a 4-pound bag? That’s 64 ounces total (since there are 16 ounces in a pound). Time for some math.

- Grabbed my trusty scale and an empty cup.
- Started scooping sugar into the cup until it hit that 7-ounce mark.
- Then, I emptied that cup into a bigger bowl and kept track.
- Repeated this, scoop after scoop, until the bag was empty.
Let me tell you, it was a bit of a process. Sugar everywhere, by the way. But hey, all in the name of science, right? After what felt like forever, I counted up the cups in the bowl. Drumroll, please…
It turns out, a 4-pound bag of sugar holds about 9 cups. Give or take a little, because let’s be real, I’m no scientist and my kitchen scale has seen better days. Some sources I peeped said around 9.02 cups or even 9 and 1/3. So, I wasn’t too far off the mark. And honestly, it depends on how tightly you pack that sugar in the cup.
So there you have it, folks. If you ever find yourself staring at a recipe and a 4-pound bag of sugar, just remember: you’re working with roughly 9 cups. Hope this little kitchen adventure helps someone out there. I’m gonna go clean up this sugary mess now. Catch you all in the next one!
