How File Size Conversion Works

Common units

File sizes are commonly shown in KB, MB, GB and TB.

Simple conversion

For everyday estimates, 1 GB is about 1000 MB and 1 TB is about 1000 GB.

Binary values

Some systems use 1024 instead of 1000, which is why storage numbers can look slightly different.

Practical use

File size conversion helps estimate storage needs, download time and cloud backup space.
