How much LPG gas required for one cup of tea?

The amount of LPG gas required to boil water for one cup of tea is relatively small, typically around 0.1 to 0.2 kg of LPG. This estimate can vary based on the efficiency of the stove, the initial temperature of the water, and the specific boiling time. Generally, boiling about 200-250 ml of water for tea may use around 10-15 grams of LPG.
