Terabytes to Gigabytes Converter
Terabytes describe hard drives, NAS boxes, and cloud backup plans, while gigabytes are the currency of everyday files. Converting TB to GB helps you plan: will a 4 TB drive hold your 800 GB photo library, or how many 50 GB games fit on a 2 TB console drive? One terabyte equals 1024 gigabytes — multiply terabytes by 1024. The converter above handles it instantly in both directions, the table covers typical drive sizes, and the FAQs explain the gap between marketed and actual usable capacity.
