The scale can only measure mass. It looks like there’s some function to convert between mass and volume, but it can only do that by assuming a density. In this cases it seems to be defaulting to the density of water.
Since Ice cream is made from ice and probably decently aerated, it’s gonna be much less dense than water. To summarize: the mass from the scale and the volume on the tub are both correct. The volume from the scale is incorrect.

237 ml of ice cream will have a different reading in grams, only water will have a perfectly 1 ml = 1g conversion

Not a math guy huh op

Im not certain what you find confusing? Unless your weighing water, the grams to fl oz/ml is always going to be different. Because one is mass and one is weight

As others have mentioned, the volume measurement on your scale is only valid for water, for which 1 mL = 1 g. I think it’s kind of silly that the function is even there. There are some food scales out there that have a milk volume measurement, using a different conversion factor. The volume measurement is not going to work if you try to measure anything with a different density. I mean, think about it, how can a food scale actually measure volume?

It’s specific gravity. Water is 1=1 so just about all water based liquids can be calculated as such. Since ice cream is churned with air, it makes the ice cream less dense. So for this particular ice cream (they are all different btw) it’s a multiplier of 1.53 or so.

Alright, I’m gonna give a way to calculate calories for this. First, I’m gonna assume the tub is about ~20g, to get the most accurate results, eat the whole tub, then find out its weight! Then, it would be 280 calories / 141 grams = 1.986 calories per gram.
Let’s say you ate 60 grams, so 60*1.986 = 119.2 calories ate
Have fun with this, or not, I would just eat the whole tub, which makes everything nice and simple :).
