As you probably already know, the actual capacity of a hard disk or memory is significantly lower than what the manufacturer sells us. It is not that we are being deceived but that there is a different interpretation than we usually think. While we know that 1 GB is 1024 MB, a manufacturer makes a different conversion and says that 1 GB is 1000 MB, therefore, the greater the capacity of the memory or hard disk, the greater the error.
For calculate the actual capacity of a hard drive or memory you have our online tool that will calculate the space to store content by simply entering the capacity indicated by the manufacturer. Keep in mind that if it is a mobile or other device that requires added applications or manages an operating system, this memory figure may be even lower.
