你買了一隻重28.9擔的牛
一路笑緊你係physics 討論叫買餸
然後你舉出黎個例子竟然係講買牛
你到底有幾中意煮野食
On a spending spree in Malaysia, you buy an ox with a weight of 28.9 piculs in the local unit of weights: 1 piculs =100 gains, 1 gain =16 tahils, 14 tahils =10 chees, and 1 chee =10 hoons. The weight of 1 hoon corresponds to a mass of 0.3779 g. When you arrange to ship the ox home to your astonished family, how much mass in kilograms must you declare on the shipping manifest?
