Multiples of a given quantity are typically expressed using derivatives of Latin numerals. This list is fairly exhaustive, in fact only a handful of these words can be found in the Oxford English Dictionary. Perhaps, many of these terms have never even been used in a sentence! But you just never know when you might need one of them. Yet there are even brainier terms, such as:
sesquiduple - Involving a ratio of 2 1/2 to 1.
sexagecuple - Involving a ratio of 60 to 1.
tantuple - That is so many times another quantity; equimultiple
Should you have have to go beyond what is available on this page, feel free to use this one:
