1. There are two ways to measure the capacity of common rice cookers on the market. One is the volume of meters (in liters), and the other is the volume of "meters+water" (in liters). The former takes Panasonic rice cookers as an example, and the common models are XXX 10, XXX 15 and XXX 18. Among them, Arabic numerals represent the maximum volume of rice that a pot can hold. The latter takes domestic rice cookers such as Midea as an example. Its capacity is generally in liters, usually 3 liters, 4 liters and 5 liters, which means the volume of "rice+water".

2, first of all, take cooking as an example, xxx 10 pot, 1-4 people; Xxx 15 pot, 2-6 people; Xxx 18 pot, 2-8 people. If you cook porridge, you can actually measure it with your own bowl according to the scale line of the inner pot. Take xxx 15 pot as an example. When the water level is at the maximum scale, you can cook porridge for 3-4 people. Xxx 10 pot, estimated 1-2 people; Xxx 18 pot is estimated to have about 3-5 people.

According to the above, one of us probably chooses about 2 liters.
