1. One liter is equal to 1000 milliliters. Using the density of water as a reference, one liter of water weighs approximately 2 jin (斤).
2. The density of Baijiu (白酒) is less than that of water, with 50-degree Baijiu having a density大约为0.9克/毫升 (approximately 0.9 grams per milliliter).
3. Consequently, one liter of 50-degree Baijiu weighs roughly 1.8 jin (斤).
