How heavy is kong?

So kong to me looks like he is quite heavy but defo not nearly as heavy as Godzilla or MechaG, he quite easily was able to climb onto mechaG and didn’t seem to weigh him down a bit, mechaG didn’t even notice kong was on him until he stopped his punch.

So, noting that Godzilla is like at least around 90,000 tonnes from last time I checked and assuming MechaG is around the same or slightly lighter, kong should be maybe around 40 - 60,000 tonnes? I’ve always had trouble with this cos I don’t think his weight was ever confirmed. But he looks to be heavier than mothra and rodan and those slightly shorter titans who which I’m pretty sure weight around 20-30,000 tonnes and probably around the same as behemoth or the larger mutos? I wanna hear everybody’s thoughts on this.
