Theoretically, if it has a tare weight stamped on it and you weigh it then you know the weight of the gas.

There isn’t anything relating to weight
If I can get it weighed what’s the calculation needed to calculate gas ?

Total weight - tare weight = weight of gas.

Maybe only the Brits demand a tare weight is stamped.

I’m trying to find the total litres is that wrong ?

Assume that liquid Propane is ½ the weight of water
(whilst Propane gas is about 1½ times heavier than air).

The filled weight less the empty weight of the bottle is the weight of liquid inside.
Multiply the weight of liquid in kilogrammes by two to get the number of litres present.

They are 12.5 kg cylinders.
Depending on type of gas this should give you a good guide.

The tare is usually stamped into the ring around the base.

#### Guigsy

Looks like their 12.5kg bottle? So about 25 litres?

Why not wait until you’re bottle is empty then weigh it,buy a full one and weigh that then you will know the weight of the gas. You can then use the above formula to calculate the litres. Or you could ask the supplier how many litres in a bottle

Except all the bottles tare at a different amount

Can’t be that much difference between each bottle so long as it’s the same type. He only wants a rough idea.
