Is there an online tool that will tell me how much memory size that has mixed in MB and GB so I can get a better idea of how much is the total size used by all the files?

    What do you mean? What would you input, and what would get out?

    You enter a list of sizes in MB/GB/etc and as an output you get the total. Correct?

    You want to enter file sizes in MB or GB, and have it perform a sum regardless of the units used, correct? Apr 22, 2016 at 17:10

    @RockPaperLizard Yes that is right.

Wolfram Alpha. For example "3721304KB + 700Mb + 20gb", will output 23.81GB, or any unit needed, e.g. 2.381×10^10 bytes, 1.905×10^11 bits, etc.

The main defect of WA is that it's proprietary, and it's (deliberately) difficult to copy data from.
