TB to Bytes Converter

How to convert terabytes to bytes

FormulaB = TB × 1,000,000,000,000

Multiply the value in terabytes by 1,000,000,000,000. To go the other way, multiply by 1×10⁻¹² (or divide by 1,000,000,000,000).

A terabyte is larger than a byte: one terabyte contains 1,000,000,000,000 bytes.

About the units

Terabyte (TB)

10¹² bytes. Hard drives and SSDs are marketed in decimal terabytes. One terabyte equals 8,000,000,000,000 bits (b).

Byte (B)

Eight bits; the basic addressable unit of memory. One byte equals 8 bits (b).

Frequently asked questions

How many bytes are in one terabyte?

There are 1,000,000,000,000 bytes in one terabyte, and this value is exact by definition.

How do I convert terabytes to bytes?

Multiply the number of terabytes by 1,000,000,000,000. For example, 10 TB × 1,000,000,000,000 = 10,000,000,000,000 B.

How many terabytes are in one byte?

One byte equals 1×10⁻¹² terabytes. That is the reverse factor, 1 ÷ 1,000,000,000,000.

What is 10 terabytes in bytes?

10 TB = 10,000,000,000,000 B.

Is this TB to B converter accurate?

Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
