400 Bytes to Bits

400 bytes is equal to 3,200 bits, or 3.125 Kb.

This page explains the formula, works through examples and lists common values in a conversion table.

How to convert bytes to bits

Multiply the value in bytes by 8 to get bits.

b = × 8
  1. 1Start with the value in bytes: 400 B.
  2. 2Apply the formula: × 8 = 3,200.
  3. 3Round to the precision you need: 3,200 b.

Digital units here use binary multiples: 1 kilobyte = 1,024 bytes.

Examples

10 B to b × 8
= 80 b50 B to b × 8
= 400 b250 B to b × 8
= 2,000 b

About the units

Byte (B)

A unit of digital. 1 B = 8 b.

Bit (b)

A unit of digital. 1 b = 0.125 B.

Accuracy and rounding

The calculation uses exact decimal arithmetic, so the conversion itself adds no error. Results are rounded to six significant figures; the formula steps show more digits.
