Hard drive sizes are typically marketed using the decimal meaning of prefixes, whereas RAM uses binary meanings. For example:
A 10 GB hard drive (common only a few years ago) typically has 10,000,000,000 bytes 10 GB of RAM though is equal to 10,737,418,240 bytes
More information about this can be found here.
The problem is to take 2 inputs based upon decimal prefixes (a number representing size and a string representing the units) and output the equivalent size using binary prefixes, as seen below:
, 'MB' -> [95.4] , 'GB' -> [93.1]
