# Terabytes to bits

**1 terabyte in bits: 1 TB = 8,000,000,000,000 bit**

bit = TB × 8,000,000,000,000

To convert terabytes to bits, multiply by 8,000,000,000,000. 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 bit = TB × 8,000,000,000,000. Both units measure data, so the conversion is a fixed factor that never changes.

## Common questions

### How many bits are in one terabyte?

One terabyte equals 8,000,000,000,000 bits. bit = TB × 8,000,000,000,000.

### How do you convert terabytes to bits?

Use bit = TB × 8,000,000,000,000. So 10 TB is 80,000,000,000,000 bit.

### How many terabytes are in one bit?

One bit equals 1.25 × 10^-13 terabytes, which is the reverse of the conversion above.
