512 GB to TB
512 gigabytes to terabytes
Decimal (SI) — what most people mean
512 GB = 0.512 TB
Binary (IEC): 512 GB = 0.5 TB
In the decimal standard (used by storage makers and Google), 1 GB = 1000 of the next unit down, so 512 GB = 0.512 TB. Operating systems use the binary standard (×1024), giving 0.5 TB.

Frequently asked questions
How many terabytes is 512 GB?+
512 GB equals 0.512 TB using the decimal (SI) standard that drive makers and Google use, or 0.5 TB using the binary standard that operating systems use.
Why are there two answers?+
Storage is measured two ways: decimal (1 TB = 1000 of the next unit down) and binary (1 TB = 1024). Hard-drive and SSD capacities are advertised in decimal, while Windows and other systems report sizes in binary — which is why a "1 TB" drive shows as about 931 GB in your operating system.
