Data Storage Converter

Hard drive manufacturers label drives using decimal counting (1 TB = 1,000,000,000,000 bytes) but operating systems use binary measurement where 1 GB = 1,073,741,824 bytes. So that 1,000,000,000,000 bytes divided by 1,073,741,824 equals about 931 GB in Windows. You are not losing any storage - it is a labeling difference.

GB (gigabyte) and GiB (gibibyte) both equal 1,073,741,824 bytes (2^30) in this converter, following the binary standard used by operating systems. The GiB notation is the formal IEC name while GB is the commonly used label. In practice, they refer to the same amount of data.

To convert megabytes to gigabytes, divide by 1024. For example, 2048 MB equals 2 GB. A typical smartphone photo is 3-5 MB, so a 128 GB phone can hold roughly 25,000-40,000 photos.

1 TB equals 1024 GB. A 1 TB drive can hold roughly 250 HD movies, 200,000 MP3 songs or 250,000 smartphone photos at typical file sizes. For gaming, a 1 TB PS5 SSD fits about 10-20 modern games.

1 petabyte equals 1024 terabytes. A petabyte can hold roughly 250,000 HD movies or 500 billion pages of text. Petabytes are used in data center planning, cloud storage pricing and internet traffic measurement.
