CALOR GAS CYLINDER WEIGHTS

Just been trying to establish how much gas is left in the cylinders in my stash. I have 7 spare cylinder's aquired over the years - 5 X 6kilo [lite] propane and 2 X 6kilo steel propane plus 2 X 6 kilo [lite] propane in the 'van. Now I know the "lite" cylinders have nifty gauges but I tend not to trust these too much.

Anyway going to France and Spain for six weeks in August. I like to take 2 x full cylinders [as near as makes no difference] with me so I was attempting to save a bob or two by finding a couple of cylinders with sufficient gas to run out in the 'van over the next few weeks in the uk and then replace with full cylinders. I hate to "chop in" cylinders for replacement with gas still in them. It offends the Scot in me.

Easy I thought to establish how much gas in the cylinder - weigh the cylinders as is and then subtract the "bare" weight of the cylinder [as listed in the Site Directory and Handbook on page 657] a small calculation is required to get the bare cylinder weight but hey I have a calculater.

To cut a long story short the weights as detailed in the handbook do not seem to be correct. A full Calor lite 6 kilo cylinder weighed on my state of the art luggage scales comes in at a tad under 10.5 kilo and not as stated 8.7 kilo in the handbook. The metal collar on the cylinder lists the "bare" weight as 9lb 12oz which converted is 4.42 kilo  - add to this 6 kilo of gas and you have 10.42 kilo cylinder and gas. [Handbook 8.7 kilo] Likewise the steel 6 kilo propane calculates out at 14.4 kilo as compared to the handbook quoted weight of 13 kilo.

Hardly earth shattering you may say but using the handbook figures didn't half confuse the life out of a simple chap like me.

Would someone out there check my figures and confirm that I am right or if I am wrong tell me where I have screwed up
