250 GB to TB
250 gigabytes to terabytes
Decimal (SI) — what most people mean
250 GB = 0.25 TB
Binary (IEC): 250 GB = 0.2441 TB
In the decimal standard (used by storage makers and Google), 1 GB = 1000 of the next unit down, so 250 GB = 0.25 TB. Operating systems use the binary standard (×1024), giving 0.2441 TB.

Frequently asked questions
How many terabytes is 250 GB?+
250 GB equals 0.25 TB using the decimal (SI) standard that drive makers and Google use, or 0.2441 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.
