How can one get the actual weight of a hot object? Is there a mathematical or any expression that helps to correct for the convection caused by hot air?

Is it floating too? You can't put it on a scale, OR you think that its

heat make it seem to weigh less than it really does, even if it's

sitting on a scale? Which?

In a quick (not thorough) search, I found the following: https://www.sciencedirect.com/science/article/abs/pii/0040603186800107

The authors of this paper suggest that convection can create errors in weighing of the order of micrograms. Of course, that would depend on many, many details. I don't think there is any hope of applying a simple formula to calculate a correction. Avoiding the issue by suppressing convection is still your best bet.
