Bits To Bytes Calculator

Work out bits to bytes instantly with clear inputs, formula shown and shareable results.

About Bits To Bytes Calculator

Converting Bits to Bytes is one multiplication: a single bit is 0.125 B, so the amount is scaled by that factor. Reversing the direction divides by the same factor. The factor is an exact definition rather than a rounded figure, so the result stays precise at any magnitude. Eight bits to the byte has been standard since the 1960s, though early machines used 6, 7 and 9 bit bytes.

Formulas

Bits → Bytes

B = bit × 0.125

Bytes → Bits

bit = B ÷ 0.125

Worked example

With the default values below, Bits To Bytes Calculator returns Converted Value of 128.000000. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 8 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How many B are in one bit?

One bit equals 0.125 B. That value is exact by definition.

How do I go from Bytes back to Bits?

Divide by 0.125 rather than multiplying, or flip the direction selector which does it for you.
