About Converting Petabits to Bits
Petabit and Bit are everyday digital-storage units, used for everything from file sizes and app downloads to storage device capacity and mobile data allowances. Specifically: Petabit digital storage unit, and bit digital storage unit.
Formula
bits = petabits × 1e+15
This factor comes from each unit's defined relationship to the category's base unit: 1 petabit equals 1e+15 base units, and 1 bit equals 1 base unit, so dividing one by the other gives the direct petabit-to-bit factor of 1e+15.
Simple example
1 Pb × 1e+15 = 1e+15 bit
1 petabit = 1e+15 bits.
Real-world example
500 Pb × 1e+15 = 5e+17 bit
500 petabits = 5e+17 bits.
Conversion table

Reverse conversion: Bit to Petabit
1e+15 bit × 1e-15 = 1 Pb
1e+15 bits = 1 petabit.
petabits = bits × 1e-15

Frequently asked questions
How many bits are in 1 petabit?
1 petabit equals 1e+15 bits, using the exact defined conversion factor rather than an estimate.
How do I convert petabit to bit?
Multiply the petabit value by 1e+15. The converter above does this instantly to whatever precision you set.
How do I convert bit back to petabit?
Use the reverse factor: 1 bit equals 1e-15 petabits. You can also use the swap control in the converter above to flip the direction instantly.
What is a petabit?
Petabit (Pb) is a unit of digital storage.
What is a bit?
Bit (bit) is a unit of digital storage.
Is the petabit to bit conversion exact?
Yes. Both petabit and bit are defined by fixed standards rather than physical artifacts, so the factor of 1e+15 used above is exact to as many digits as you choose to display.
