6kg propane gas bottle

[Alymar]

Hi,hope all are well.
I have a just swapped a 6 kg propane bottle. The tare weight on the metal collar is 16.12 which equals 7.5 kg. The toat weight with 6 kg of gas should be 13 .5kg, the actual weight on digital scales is 14.7kg which would suggest there is 7.2kg of gas in the bottle. I have checked my scales against a known weight and they are spot on. Any body else come across this. TIA.

I have had it the other way, supplier was gobsmaked when I pulled my hand scales out and rejected 2 bottles before the 3rd one being correct
