Common Conversions
How to Convert GB to TB
1 TB = 1,024 GB (binary) or 1,000 GB (decimal). Divide GB by 1,024 (or 1,000) to get TB. So 2,048 GB = 2 TB binary, or 2.048 TB decimal. As with all data conversions, OS and consumer/marketing usage diverges - drives marketed as '1 TB' actually deliver 0.91 TiB (931 GiB) in OS terms.
Useful for planning large storage purchases. A 4 TB external drive holds about 4,000 GB of files (decimal) or 3,725 GiB in OS view (binary). Cloud storage commonly purchased in TB increments (1 TB iCloud, 2 TB Google One). Personal media archives can grow into TB territory quickly with 4K video.

Frequently Asked Questions
What can I store in 1 TB?
About 250,000 photos at 4 MB each, or 250 hours of HD video, or 200 typical games (50 GB average), or about 500,000 documents. Modern phones can shoot 100 GB of 4K video per hour, so a TB holds about 10 hours of 4K phone footage.
Are SSD and HDD storage measured the same?
Yes - both use the same GB/TB measurements. SSDs are typically smaller capacity per dollar but much faster. Modern SSDs and HDDs both use the decimal marketing standard (TB = 10^12 bytes), so a '1 TB SSD' and a '1 TB HDD' have nominally the same capacity.
