So I thought I would share this neat little formula for tomato weights. I found this on a website that deals with these giants, I think they do judging at exhibition shows.
First take a circumference measurement from stem end to blossom end. This has to be in cm or it won't work. We will call that one cc1.
Then take another circumference measurement, the same as above, except angle it to the side of the tomato keep that measurement. We call that cc2. That was hard to explain...
Lastly, take a circumference measurement around the tomato, horizontally if you can picture that. Calling that cc3.
Here is the math part, for cc1, 2 and 3 enter you measurements there. The little star thingy means multiplication.
Formula:
0.016887*cc1*cc2*cc3=
(Example for mine); 0.016887*29.2*26.6*31.7=415
When you get your answer don't worry about the decimals you only need what's in front of it. You only need one number behind the decimal for your measurements you plug in.
Take the answer you got and multiply it by .90 for a green tomato and .95 for a red tomato.
(Example of mine); 415*.90=373.5
The answer you get there is weight in grams, you can then covert that to kg or pounds.
I got 0 lbs 13 oz. One pound is 16 ounces so it's about 3 ounces short of a pound. Now this is just an estimation, but should be close within a couple grams. Hope you enjoyed this very boring math lesson. Lol.
