The method is as follows:

First, turn on the natural gas stove to maximize combustion.

Second, remember the current reading of the natural gas meter and the current time of the watch.

Observe the reading of the natural gas meter after three or five minutes.

4. Subtract the last meter reading of natural gas from the current meter reading of natural gas, and then multiply the difference by 12, and the result is the gas consumption of one hour.

If you want to be more accurate, you can use the above method to calculate the consumption of ten or fifteen minutes.

It should be noted that 10 minutes needs to be multiplied by 6, and 15 minutes needs to be multiplied by 4.
