I think you should be OK for a weekend at least, but if you're going away for a fortnight it might be an idea to either take a spare, or, probably a cheaper option, a smaller (cartridge) stove to use while you're looking for somewhere to exchange the bottle when it runs out!

I read a tip in a caravan mag that if you pour a kettle of boiling water over it you can tell how full it is as the gas bit will still be cold - dont know if it works but am going to find out as we dont know how much is left in ours!
Take the above advice. Simple and effective. The gas is in a cold liquid state when it is in the bottle and so the metal bottle does not heat up at the level of the liquid. The empty space above the liquid allows the metal bottle to heat up.
Just pour some hot/boiling down the side of the bottle wait a few seconds so you dont get scolded and run your hand slowly down the same area. Where the side of the bottle gets cold is the top of the liquid level ie how much is left in your bottle!

The Calor Gas website tells you the weight for all their gas bottles.
But the exact weight (to the nearest ounce) of the empty individual cylinder may vary because of manufacturing tolerances, hence the embossed collar which I imagine is at least checked and probably renewed prior to filling.
From the Calor site:
"Calor’s 5kg and 13kg Patio Gas® cylinders and the Calor Lite® are fitted with Calor's new Gastrac® - an indicator which tells you when you are running low on gas.
For all other cylinders, the empty tare weight can be found on a metal disc on the shroud, this gives the weight of the cylinder in pounds and ounces. To convert this to kilograms multiply this number by 0.453592. Once you have the empty weight of the cylinder you can put it on some scales, then you will have the total weight, so you can now take the empty cylinder weight off the total, this will give you how much gas you have left in the cylinder.
» What is the empty weight of bottles?
All bottles will vary depending on their size, etc. The weight written on the metal disc on the shroud is the weight of the empty cylinder."
We use Calor lite at it comes with a little guage on the top. Not ultra accurate, but when the guage starts to go down, it's nearing the end. As HacksawBob says, it's an indication of when the bottle is getting low - it stays on full for most of the time.
have just been afflicated by the caravanners impulse buy syndrome and have bought one of those magnetic gas gauge jobbies, well for 2 quid i figured i'd give it a go, hopefully it'll work , if not, it's back to the scales
got some of these too don't know what i'm gunna use 'em for but they look as though they might come in useful at some stage,
------------- no tin tent outings booked as yet ,just another cruise in Sept' booked so far
