# Bytes to terabytes

**1 byte in terabytes: 1 B = 1 × 10^-12 TB**

TB = B × 1 × 10^-12

To convert bytes to terabytes, multiply by 1 × 10^-12. 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 = B × 1 × 10^-12. Both units measure data, so the conversion is a fixed factor that never changes.

## Common questions

### How many terabytes are in one byte?

One byte equals 1 × 10^-12 terabytes. TB = B × 1 × 10^-12.

### How do you convert bytes to terabytes?

Use TB = B × 1 × 10^-12. So 10 B is 1 × 10^-11 TB.

### How many bytes are in one terabyte?

One terabyte equals 1,000,000,000,000 bytes, which is the reverse of the conversion above.
