terabit to petabyte
Convert terabit (Tbit) to petabyte (PB). Use an editable data storage converter, conversion formula, and reference table.
1 Tbit = 0.000125 PB
Conversion formula
One terabit equals 0.000125 petabyte. Multiply your value in terabit by this factor to get petabyte. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 terabit:5 × 0.000125 = 0.000625 PB

About these measurements
Data storage expresses a number of bits or bytes.
The base reference used here is the byte. One terabit is 125,000,000,000 base units; one petabyte is 1e+15 base units.
Important distinctions
Decimal prefixes use powers of 1,000; binary prefixes use powers of 1,024. One byte is eight bits.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
