To determine how much rice you can cook in an 8-liter pressure cooker, you need to consider the water-to-rice ratio and the amount of space the rice and water will occupy during cooking. The typical water-to-rice ratio for cooking rice in a pressure cooker is 1:1.5. That means for every cup of rice, you'll need 1.5 cups of water.
First, let's convert the 8 liters capacity of the pressure cooker to cups. There are approximately 4.22 cups in a liter.
8 liters * 4.22 cups/liter ≈ 33.76 cups
Now, considering the 1:1.5 water-to-rice ratio, the maximum amount of rice you can cook in the 8-liter pressure cooker is:
33.76 cups / 1.5 ≈ 22.5 cups of rice
Keep in mind that the rice will expand during cooking, so you may want to avoid filling the pressure cooker to the brim to prevent any potential spillage or clogging of the pressure release valve. It's a good idea to leave some space for the rice to expand. A safe and practical maximum amount to cook would be around 20 cups of rice in an 8-liter pressure cooker.
