Okay, so I was trying to make this lemon meringue pie the other day, you know, the one from Grandma’s old recipe book? The recipe calls for “1 tbsp of lemon juice,” but here’s the thing – my kitchen scale only measures in grams. So, I’m stuck trying to figure out how many grams are in a tablespoon of lemon juice.
First, I grabbed a lemon from the fridge. It was a pretty average-sized one. I rolled it on the counter a few times to get the juices flowing – an old trick I learned from watching cooking shows. Then I sliced it in half, and wow, it looked super juicy!

I took one of those halves and squeezed the heck out of it over a small bowl. I wanted to see how much juice I could get from just half a lemon. Then I did the same to the other half, pouring it in with the first batch. I have to say that it is hard to squeeze the lemon by hand.
Next, I zeroed out my kitchen scale and carefully poured the lemon juice onto it. I was mostly trying to get an idea of how much liquid was in a whole lemon.
Here is my records about the weight:
- Weight of lemon juice from 1 lemon: 30 grams
Now, the recipe called for 1 tablespoon. Since my experiment showed that the whole lemon was about 30 grams, and I knew from somewhere on the internet that a whole lemon usually has about 2-3 tablespoons of juice. I decided to just divide that by 2 and got my answer.
My Results
So, I did a rough calculation in my head and figured 1 tablespoon of lemon juice is about 15 grams. That’s what I ended up using for the pie.
And you know what? The pie turned out pretty darn good! The filling had just the right amount of tartness. So, I guess my little experiment worked out!
So, there you have it, if you are looking for how many grams is 1 tbsp lemon juice, it is about 15 grams.

I hope this helps someone else who might run into the same problem in the kitchen!
