Petabyte to Terabyte Converter (PB to TB)
1 petabyte equals 1,000 terabytes (1 PB = 1,000 TB) — multiply the number of petabytes by 1,000 to convert. In the decimal (SI) storage convention each step from terabyte to petabyte is exactly one thousand, so a petabyte holds a thousand terabytes.
The formula
To convert petabytes to terabytes, multiply by one thousand:
TB = PB × 1,000
For example, 7 PB × 1,000 = 7,000 TB. To reverse it, divide terabytes by 1,000.
