9kg Gas Bottle

A 9kg gas bottle is considered the standard size BBQ gas bottle and is roughly equivalent to a 20 lb propane tank. 9kg represents the nominal weight of the gas contents. A 9kg gas bottle weighs approximately 17.5 kg when full, so it is very portable.


Please see Are BBQ Gas Bottles 9kg or 8.5kg?


How much does a 9kg gas bottle weigh when full?

A 9kg gas bottle weighs 16.3–19.0 kg* when full. The weight variation is in the empty 9kg gas bottle weight, do to manufacturing variances. 9kg refers to the weight of the contents only.

How much a 9kg gas bottle weighs when full depends on the tare weight (empty weight), which can vary. The tare weight plus the 9kg contents weight equals the 9kg gas bottle weight when full. So, let’s assume the tare weight is 8.2kg (just an example), then a 9kg gas bottle weight when full is: 9 + 8.2 = 17.2kg.

Just read the actual tare weight off of the neck ring. Tare weight is labelled as TW in the accompanying image of a neck ring stamp. How much does a 9kg gas bottle weigh when full just requires some simple addition.

Some simple addition answers the question regarding how much a 9kg gas bottle weighs when full.

*9kg gas bottle weights shown are approximate.

The weight range of 9kg gas bottle empty weight is 7.8kg to 10.4kg. The 9kg gas bottle empty weight, or tare weight, is stamped on the neck ring of the bottle. As there are many manufacturers of 9kg gas bottles, gas bottle sizes and gas bottle dimensions vary significantly.

To calculate the full weight, you add 8.5kg to the empty (tare) weight of the bottle and the total is the full weight.

Full Weight – Tare Weight = Gas Remaining

A 9kg gas bottle will last about 7 to 8 days cooking a meal a day on a 4 burner BBQ grill, assuming a one hour cook time per meal. A 9kg gas bottle (patio gas) will last about 29 hours, when cooking with a small 2 burner compact BBQ used on high. It will last even longer on lower settings or if only one burner is turned on.

It really depends on the gas burner and gas consumption rating of the BBQ or patio heater being used.

Due to the popularity of SWAP’n’GO gas bottles, staffing issues and safety concerns, all of the major oil marketing companies removed refilling from their company owned sites pre-2010. A big reason was no waiting to refill gas bottle at petrol station.

The remaining refillers are independent service station operators and multi-site groups, although some have major oil company branding.

The numbers have now stabilised and no further significant reduction of refiller sites is expected.

Elgas is one of the largest suppliers of LPG to BBQ gas bottle refillers and we support them as well as our SWAP’n’GO network.

In fact, many of our independent customers have both SWAP’n’GO and Elgas BBQ gas bottle refill gas.

  • LPG gas bottle storage is best outdoors in a well ventilated space.
  • LPG gas bottle storage should never be stored indoors.
  • LPG gas bottle storage should always be stored upright.

  • If you store your BBQ or patio heater indoors, when not in use, you should always detach the BBQ gas bottle first and store it separately outdoors.

Manually refilled cylinders can be incorrectly filled causing the cylinders to vent gas through the pressure relief valve that is part of the main valve.

This can happen, with an overfilled cylinder, as the gas gets warmer and the pressure builds.

Venting can be a very dangerous situation if it occurs near people or an ignition source and especially in vehicles.

SWAP’n’GO® BBQ gas bottle refills are done by weight on very accurate digital scales.

The total BBQ gas bottle refill weight is calculated based on the empty weight of the cylinder plus the gas.

The scales are reset for each cylinder to achieve the proper full weight. So, you can rest assured that the BBQ gas bottle refill you buy from SWAP’n’GO is safely filled.

SWAP’n’GO also performs two leak checks on each cylinder before it is delivered to your local dealer.

We always check the inspection date on every cylinder we fill and only those with valid dates are filled.

Cylinders with expired dates are inspected internally and externally, have new valves fitted and have a new date stamp applied.

Also, no waiting to refill gas bottle at petrol station.

In Australia, this is a very unlikely problem, as the temperature would need to be far below zero.

Extremely cold sub zero conditions can affect your BBQ gas bottle, particularily as it gets low on gas.

There could be liquid gas within the bottle that will not come out.

The reason for this is that the liquid gas absorbs heat from the metal walls of the BBQ gas bottle to achieve vapourisation, which is the process of going from a liquid to a gaseous state.

As the volume of liquid gas gets lower, there is less metal surface area providing heat to the gas so it may not ‘boil’ and vapourise in extremely cold conditions, when the metal BBQ gas bottle become very cold.

The best solution for this is to keep the bottle in the sun, on cold days, so it absorbs as much heat as possible.

Alternatively, switch to a full or near full BBQ gas bottle.

You can use the lesser filled bottle on another day, when the temperatures are warmer.
