How to convert bits to bytes

To convert bits to bytes, multiply the number of bits by 0.125.

Formula

B = bit × 0.125

Examples

  • 5 bit = 5 × 0.125 = 0.625 B
  • 25 bit = 25 × 0.125 = 3.125 B
  • 100 bit = 100 × 0.125 = 12.5 B

Frequently asked questions

How many bytes are in one bit?
One bit is exactly 0.125 bytes.
How do I convert bytes to bits?
To convert bytes to bits, multiply the number of bytes by 8. The formula is bit = B × 8.
Is this conversion exact?
Yes. Both units have exact definitions and the factor 0.125 is exact. Displayed results are only rounded when they have many decimal places.
Which is larger, a bit or a byte?
A byte is 8 times larger than a bit. In other words, a bit is exactly 1/8 of a byte.
