JavaScript jQuery货币转换数学问题

我正在使用在线货币转换器。基本换算以欧元为单位，这意味着我在兑换欧元时会得到特定货币的换算率

例如：

1欧元=1.2万亿美元

如何使用此输出将其更改为美元作为基本输出

以下是在线货币转换器的json输出：

我希望汇率反映美元作为基本产出：

IE:1美元=0.82欧元、南非兰特、其他货币

可以使用此输出进行转换吗？

如果要将json从欧元修改为美元：

var s='{“success”：true，“timestamp”：1613901367，“base”：“EUR”，“date”：“2021-02-21”，“rates”：{“AED”：4.45116，“AFN”：93.99，“ALL”：123.72，“AMD”：635.578463，“ANG”：2.1788，“EUR”：1，“USD”：1.211825}；
var t=JSON.parse；
风险值比率=t[‘比率’]；
var base=t['base']
风险值结果=兑换成（“美元”）；
控制台日志（结果）；
功能转换（设计）{
var v=利率[基准]/利率[设计]；
用于（常数输入率）{
t['rates'][key]*=v；
}
t['base']=设计；
返回JSON.stringify（t）；
}

尝试从转换器获取美元的兑换率，因为兑换率取决于货币到货币的级别。
