The Star of Africa, a diamond in the royal scepter of the British crown jewels, has a mass of 530.2 carats, where1 carat = 0.20 g. Given that 1 kg has an approximate weight of2.21 lb, what is the weight of this diamond in pounds?
On a spending spree in Malaysia, you buy an ox with a weight of 28.9 piculs in the local unit of weights: 1 picul = 100 gins, 1 gin = 16 tahils, 1 tahil = 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? (Hint: Set up multiple chain-link conversions.)
