The rice bowls used by China people are not more than 12 cm in diameter because they are about 12 cm in diameter when their hands are put together. In other words, making the diameter of the bowl less than 12 cm is the most suitable for one hand.
The volume ratio of boiled rice water to rice is 1: 1.5, which is about1:1in terms of mass. That is to say,100g of uncooked rice is about100g of water. According to the law of conservation of matter, it can be roughly estimated that the cooked rice is about 200g, which is 4 Liang.
Rice generally refers to cooked rice, which will expand after cooking, and the weight of a bowl of raw rice and rice is also different. In addition, 100g uncooked rice can generate 360 kilocalories. 100g cooked rice will use less raw rice than100g, so the heat will be less than 360 kcal.
100 grams of cooked rice generally has a calorie of about 270 kcal. The generation of heat is usually related to the cooking method. The heat generated by100g fried rice is higher than that generated by steamed rice or rice cooker.
The heat is also related to the variety of rice. For example, the heat generated by glutinous rice is higher than that generated by ordinary rice, while the heat generated by small rice is lower.
