Difference between Terabyte and Petabyte (TB vs PB)

Terabyte (TB)

One Terabyte is equal to 10¹² or 1000⁴ Bytes.
Terabyte is a decimal unit defined as per SI standard.
1 Terabyte = 1000 Gigabytes.
The unit symbol for Terabyte is TB.
Terabyte is not same as Tebibyte (TiB) that contains 1024⁴ bytes.
1000 Terabytes = 1 Petabyte (PB).

Petabyte (PB)

One Petabyte is equal to 10¹⁵ or 1000⁵ Bytes.
Petabyte is a decimal unit defined as per SI standard.
1 Petabyte = 1000 Terabytes.
The unit symbol for Petabyte is PB.
Petabyte is not same as Pebibyte (PiB) that contains 1024⁵ bytes.
1000 Petabytes = 1 Exabyte (EB).

How to convert Terabyte to Petabyte?

Below formula is used convert from Terabyte (TB) to Petabyte (PB) in the above TB to PB Calculator.

TB to PB Conversion Formula :

Petabyte = Terabyte x (8x1000x1000x1000x1000) / (8x1000x1000x1000x1000x1000)
or
Petabyte = Terabyte x 0.001

Terabyte to Petabyte Conversion Steps : Terabyte is first converted to bits by multiplying with 8x1000x1000x1000x1000 and then, converted to Petabytes by dividing with 8x1000x1000x1000x1000x1000. In short, we can just multiply Terabyte with 0.001 to get the value in Petabyte.
