The rupiah is the money of Indonesia. The sign is Rp.

The rupiah印尼盾 is the money of Indonesia是印尼的貨幣。The sign符號 is是 Rp。

It is not the same as the rupee, though the two words are old cousins: both go back to a Sanskrit word for a silver coin.

It is not the same as the rupee它跟rupee（盧比）不一樣， though the two words are old cousins不過這兩個字是老親戚： both go back to a Sanskrit word for a silver coin兩個都源自梵文裡指「銀幣」的一個字。

In English we say one rupiah, and in the plural people often still say rupiah (they do not always add -s). You will see very large numbers on prices, because one rupiah is a tiny amount.

In English在英文裡 we say one rupiah我們說one rupiah， and in the plural而複數的時候 people often still say rupiah大家常常還是說rupiah (they do not always add -s)（不一定加-s）。You will see very large numbers on prices你會在價格上看到非常大的數字， because one rupiah is a tiny amount因為one rupiah的價值非常小。

Though actually, in Taiwan people rarely say a Chinese version of “rupiah” in daily life; they usually call this money 印尼盾, the ready name they already have, even though 盾 is not a translation of the English word. If you say 盧比, a Taiwanese listener will think of India, not Jakarta. So hook the English word rupiah to 印尼盾, and keep rupee for 盧比.

Though actually不過其實， in Taiwan在台灣 people rarely say a Chinese version of "rupiah" in daily life日常生活很少有人講"rupiah"的中文說法； they usually call this money 印尼盾大家通常就叫這種錢印尼盾， the ready name they already have那是他們原本就有的現成說法， even though 盾 is not a translation of the English word雖然「盾」並不是這個英文字的翻譯。If you say 盧比如果你說盧比， a Taiwanese listener will think of India, not Jakarta台灣人會想到印度，不是雅加達。So hook the English word rupiah to 印尼盾所以要把rupiah這個英文字掛勾到印尼盾上， and keep rupee for 盧比而盧比留給rupee。
