since a Gigabyte is made of Megabytes, 500 Megabytes times 2, 2(500MB), is equal to one Gigabyte. (1000MB)
UNLESS, it wants the Windows way of storage, because one Gigabyte in Windows terms is actually 1024 megabytes... then it’d be 2(512MB) because 512MB and 512MB equals one windows storage gigabyte.
