I hate to party poop, but grams are units of mass not weight. So even in weightless freefall, you still have mass.

Edit: hence the classic "gravity is mass-produced" joke that's already been posted here in the comments.

Wellp. She ain't the prettiest joke, but she'll get ya there..

I challenge! I would state that if you had zero mass, you would also have zero weight in any gravity field. The joke is valid!

If you have zero mass, then you do have zero weight, but the converse is not true. You could have no weight because the net forces of gravity acting on you all equal zero and in that case you could still have mass.

So you’re saying even though my ‘gram’other is massive she weighs nothing. Now that’s a lady that can chow down on those chocolates.

But if op has no mass then they also have no weight, so the joke still works

Weight is determined by multiplying mass by gravity. So if mass is 0, weight must also always be 0. The converse isn't necessarily true, though, because you could be weightless, but still have mass as long as gravity is 0. But actually, this is technically impossible, since the gravitational force is diminished over distance but still never reaches exactly 0. However the 0 may not mean an absence of gravitational forces, but the net force of all of them being 0. This too seems only possible in theory, though. So if something is truly weghtless in nature, the mass must be 0. But this isn't about nature; the joke refers to a dream where the laws of physics don't really apply anyway. And the word "weightless" usually refers to gravity not being able to be felt, not actually a force of 0. So in conclusion, I ruined the joke.
