About Converting Terabits to Bits
Terabit 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: Terabit digital storage unit, and bit digital storage unit.
Formula
bits = terabits × 1e+12
This factor comes from each unit's defined relationship to the category's base unit: 1 terabit equals 1e+12 base units, and 1 bit equals 1 base unit, so dividing one by the other gives the direct terabit-to-bit factor of 1e+12.
Simple example
1 Tb × 1e+12 = 1e+12 bit
1 terabit = 1e+12 bits.
Real-world example
500 Tb × 1e+12 = 5e+14 bit
500 terabits = 5e+14 bits.
Conversion table
| Terabit (Tb) | Bit (bit) |

Reverse conversion: Bit to Terabit
1e+12 bit × 1e-12 = 1 Tb
1e+12 bits = 1 terabit.
terabits = bits × 1e-12

Frequently asked questions
How many bits are in 1 terabit?
1 terabit equals 1e+12 bits, using the exact defined conversion factor rather than an estimate.
How do I convert terabit to bit?
Multiply the terabit value by 1e+12. The converter above does this instantly to whatever precision you set.
How do I convert bit back to terabit?
Use the reverse factor: 1 bit equals 1e-12 terabits. You can also use the swap control in the converter above to flip the direction instantly.
What is a terabit?
Terabit (Tb) is a unit of digital storage.
What is a bit?
Bit (bit) is a unit of digital storage.
Is the terabit to bit conversion exact?
Yes. Both terabit and bit are defined by fixed standards rather than physical artifacts, so the factor of 1e+12 used above is exact to as many digits as you choose to display.
