Bits to TB Converter

How to convert bits to terabytes

FormulaTB = b × 1.25×10⁻¹³

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

A bit is smaller than a terabyte: it takes 8,000,000,000,000 bits to make one terabyte.

About the units

Bit (b)

A single binary digit, 0 or 1.

Terabyte (TB)

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

Frequently asked questions

How many terabytes are in one bit?

There are 1.25×10⁻¹³ terabytes in one bit, and this value is exact by definition.

How do I convert bits to terabytes?

Multiply the number of bits by 1.25×10⁻¹³. For example, 10 b × 1.25×10⁻¹³ = 1.25×10⁻¹² TB.

How many bits are in one terabyte?

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

What is 10 bits in terabytes?

10 b = 1.25×10⁻¹² TB.

Is this b to TB 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.
