Let me give you an idea:

This has something to do with the number of people eating every day;

There are two critical points for the number of diners, the maximum and the minimum, the minimum is 1, and the maximum is related to the dining rate (generally, the maximum and maximum dining rate is 411%, only fast food restaurants have this dining rate) and the total number of seats;

when the minimum number of diners is 1, the gas expenditure is also the smallest (only raw material processing gas, which accounts for 51%-61% of the total gas in general Chinese food), and when the number of diners is the largest, the gas expenditure is also very large;

these data are very easy to get if the restaurant uses the catering ordering system;

Let me take the data of our restaurant as an example, and make an advertisement by the way. Our restaurant is located in Pengzhou, Chengdu, and its name is Juweixuan Restaurant, Sichuan cuisine;

The dining rate in our store has been maintained at about 51%-61% for three years (here we calculate by 55%), and the daily gas consumption is about 54 cubic meters (I say cubic meters here because the charges vary from place to place), and the number of meals is 171;

calculation formula of per capita gas: per capita gas = cubic meters of gas expenditure per day/(average meal rate per meal * total number of seats * business sessions per day) per capita gas =54/(1.55*171*2)=1.289 cubic meters per person

If the Sichuan restaurant is 1511 square meters, the dining area will be 1511 * (6/. There can be 75 tables and 751 people dining at the same time. If the average meal rate of this restaurant is 51%, which is also at noon and evening, then the number of cubes per day can be calculated according to the formula:

the number of cubes per day =1.289*1.5*751*2=216.75 cubic meters, which is 216.75 cubic meters according to our Pengzhou gas price.

Of course, there must be errors in the data. You need to apply formulas to judge the final gas book according to your own environment.

And the per capita gas is only for Chinese food, even though there are many cuisines in Chinese food (each cuisine has different cooking methods, and the cooking of Sichuan food accounts for more than 81%), as well as the cooking habits of chefs, so this per capita gas of 1.289 can only be used as a reference value;

Hotpot restaurants and other stores can use the same idea to calculate this per capita gas. I don't have the data here, so I won't calculate it.
