# Bits to terabytes

**1 bit in terabytes: 1 bit = 1.25 × 10^-13 TB**

TB = bit × 1.25 × 10^-13

To convert bits to terabytes, multiply by 1.25 × 10^-13. The table below gives the values people look up most often, and the converter works for any number.

## How the conversion works

The relationship is TB = bit × 1.25 × 10^-13. Both units measure data, so the conversion is a fixed factor that never changes.

## Common questions

### How many terabytes are in one bit?

One bit equals 1.25 × 10^-13 terabytes. TB = bit × 1.25 × 10^-13.

### How do you convert bits to terabytes?

Use TB = bit × 1.25 × 10^-13. So 10 bit is 1.25 × 10^-12 TB.

### How many bits are in one terabyte?

One terabyte equals 8,000,000,000,000 bits, which is the reverse of the conversion above.
