bytes = MB × 1048576One megabyte equals exactly 1,048,576 bytes using the JEDEC binary standard (1 MB = 1024 KB × 1024 bytes). This is the unit your operating system uses to report file sizes, RAM capacity, and storage usage. Understanding the binary vs decimal distinction explains storage discrepancies: manufacturers advertise in decimal (1 GB = 1 billion bytes), while your OS reports binary (1 GiB = 1.07 billion bytes), causing ~7% apparent capacity loss.
