Digital storage conversions matter for managing files, planning backups, comparing devices, and understanding internet speeds. The field has a famous complication: the difference between decimal and binary interpretations of the same unit names.

Understanding Megabytes and Kilobytes

Storage manufacturers typically use decimal units (1 GB = 1,000 MB), while operating systems often report in binary (1 GiB = 1,024 MiB). This is why a '1 TB' drive shows up as roughly 931 GB in your file manager. Bytes, kilobytes, megabytes, gigabytes, and terabytes form the everyday ladder of digital storage.

How accurate is this conversion?

The conversions here use the decimal (SI) standard where each step is a factor of 1,000, which matches how storage and bandwidth are marketed and sold. If your operating system reports different figures, it is using binary (1,024-based) units.

All conversion factors on ClearUnits are based on internationally recognised standards (the International System of Units, SI, and official definitions). Factors are reviewed for accuracy and the calculator uses full-precision values, rounding only the displayed result.
