Many have a gas cooker that most often works with a gas cylinder. With expensive energy, the price of it has also increased significantly and you should be careful to dose its use so as not to make your cylinder last too long. It all depends on the size of the tank.
In fact, there are cylinders of different sizes. What we can tell you is that 1 kg of gas is consumed in an hour and therefore you can make the calculations based on the size of the cylinder. Certainly, we do not always cook dishes with a long preparation and then we must always make sure that the cylinder arrives full.
For this, check and only do it with the temperature. In fact, the part containing the gas is colder while the empty part has a different temperature. Otherwise, you will have to get a pressure gauge, there are also cheap ones on the market, and check that the LPG in the cylinder is correct. However, there’s another reason why you may waste gas and not make it last long enough.
