TB to Bits Converter

How to convert terabytes to bits

Formulab = TB × 8,000,000,000,000

Multiply the value in terabytes by 8,000,000,000,000. To go the other way, multiply by 1.25×10⁻¹³ (or divide by 8,000,000,000,000).

A terabyte is larger than a bit: one terabyte contains 8,000,000,000,000 bits.

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).

Bit (b)

A single binary digit, 0 or 1.

Frequently asked questions

How many bits are in one terabyte?

There are 8,000,000,000,000 bits in one terabyte, and this value is exact by definition.

How do I convert terabytes to bits?

Multiply the number of terabytes by 8,000,000,000,000. For example, 10 TB × 8,000,000,000,000 = 80,000,000,000,000 b.

How many terabytes are in one bit?

One bit equals 1.25×10⁻¹³ terabytes. That is the reverse factor, 1 ÷ 8,000,000,000,000.

What is 10 terabytes in bits?

10 TB = 80,000,000,000,000 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.
