哈利波特有多少加隆？合多少人民币？

巫师世界三种基本货币类型：
金加隆
银西可
铜纳特
加隆的边缘有一圈数字，是由古灵阁铸币妖精刻上的编号。我们还不知道西可和纳特上面是否也有这种编号，但很可能也是有的。
为了方便您计算，我们提供了巫师－麻瓜钱币换算器。
如果不用计算器的话，这些钱币的换算对麻瓜来说有点复杂，但对巫师很容易。海格说过：“金币是加隆，十七个银西可合一个加隆，二十九个纳特合一个西可，够简单了吧。 ”因此1加隆＝17西可＝493纳特
JK罗琳在一次采访（CR）中表示据她估算一个加隆的价值是“大约5英镑”，也就是7.33美元。在《魁第奇》和《神奇动物》的介绍中都提到，2千5百亿美元等于340亿加隆。即一加隆=5英镑=70人民币

J. K. Rowling sets the approximate value of a galleon at five pounds (i.e. approximately US$ 10 or € 7.5), although "the exchange rate varies".

In the book Fantastic Beasts and Where to Find Them, two pieces of information are given which hint at how much wizards' currency is worth in comparison to real-world money.
Firstly, it is said that £174 million raised for charity is equivalent to 34,000,872 Galleons, 14 Sickles, and 7 Knuts (the figure is truncated to 34,000,000 galleons in Quidditch Through the Ages). It is also stated that the book costs £2.50 ($3.99 US), or 14 Sickles and 3 Knuts.
