Data Storage Converter
Convert between bytes, kilobytes, megabytes, gigabytes, terabytes, and more.
Data Storage Converter translates digital storage sizes between bits, bytes, kilobytes, megabytes, gigabytes, terabytes, and petabytes. Understanding storage units is essential when comparing hardware specifications, planning cloud storage budgets, analyzing file sizes, or interpreting database capacity reports.
Enter a value in any unit and the tool instantly shows its equivalent in all other units. The tool supports both the binary (IEC) standard β where 1 KiB = 1024 bytes β and the decimal (SI) standard β where 1 KB = 1000 bytes β since different contexts and operating systems use different conventions.
Common conversions include understanding how many megabytes a given number of gigabytes contain, how large a file is in bits for bandwidth calculations, or converting a disk capacity stated in terabytes to the gigabytes it actually provides after formatting.

# Examples
print(bytes_to_gb(1_000_000_000)) # 1.0 (1 TB drive, decimal)
print(bytes_to_gib(1_000_000_000)) # 0.9313 (same drive, binary/OS view)
print(bytes_to_mb(500_000_000)) # 500.0 MBComments & Feedback
