Okay, so I got curious about the density of lemon juice the other day. Don’t ask me why, it just popped into my head. I figured, why not figure this out myself? It seemed like a fun little experiment.
Getting Started
First, I needed some supplies. Obviously, I grabbed a few lemons from the fridge. Then, I needed something to measure the juice with. I found a small measuring cup in the kitchen. I also grabbed my kitchen scale – the digital one, because it seemed more accurate.

Juicing the Lemons
I started by cutting the lemons in half. Then I squeezed the heck out of them, getting every last drop of juice into my measuring cup. I ended up using three lemons, just to make sure I had enough to measure properly. It was a bit of a workout, to be honest!
Weighing the Juice
Once I had all the juice, I poured it very carefully into the measuring cup. I read the volume on the small scale, and write it down. After that, I put a little container on my digital scale, tared it (that means setting it to zero), and then very, very slowly poured the lemon juice into the container. I needed to know exactly how much the juice weighed, without the weight of the container messing things up.
Doing the Math (Ugh)
So, here’s where the “science” part comes in. Density is basically how much “stuff” is packed into a certain space. The formula is super simple: Density = Mass / Volume. Mass is just a fancy word for weight, and volume is the amount of space something takes up.
I had my weight from the scale, and I had my volume from the measuring cup. All I had to do was divide the weight by the volume. I used my phone’s calculator, because, let’s be real, who does long division anymore?
The Big Reveal
After punching in the numbers, I got my result! The density of my lemon juice was a little more than water, which makes sense, think about all the pulp and other stuff that’s in there,I guess.
- Result:I am not good at remembering the exact numbers, just a little more than water.
- Note:Different lemons, different juicing techniques…your result will vary!
It wasn’t exactly a groundbreaking scientific discovery, but it was a fun way to spend an afternoon. And now I know a little bit more about lemon juice than I did before. Plus, I got to use my kitchen scale for something other than measuring ingredients for baking!
