Bytes to Bits formula and what each symbol means
bit = B × 8
| Symbol | Meaning |
|---|---|
| B | Byte |
| bit | Bit |
Bytes to Bits examples
1 B
1 B × 8 = 8 bit.
10 B
10 B × 8 = 80 bit.
100 B
100 B × 8 = 800 bit.
Bytes compared with Bits
One B is 8 times as large as one bit, so your number gets bigger when you convert bytes to bits and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
About bytes and bits
Byte (B): A byte of 8 bits. Bit (bit): One binary digit.
Where bytes to bits conversions are used
File sizes for email, uploads and downloads are quoted in kilobytes and megabytes. Memory (RAM) is usually specified in binary units.
How to calculate Bytes to Bits step by step
- Enter the value in B (the starting unit).
- Multiply by 8, because 1 B = 8 bit.
- The product is the value in bit. To go back, divide by 8 or multiply by 0.125.

- Mixing bits and bytes: 8 bits make 1 byte.
- Dividing when you should multiply: from B to bit multiply by 8; from bit to B divide by 8.
Bytes to Bits FAQ
How many bit are in 1 B?
1 B equals 8 bit.
How many B are in 1 bit?
1 bit equals 0.125 B.
Is 1 B = 8 bit an exact conversion?
Yes. The byte and the bit are both defined exactly in SI terms, so the ratio has no measurement uncertainty; 8 is just that ratio shown to 7 significant figures.
What is a bit (bit)?
One binary digit.
How can I estimate bytes to bits in my head?
One B is 8 times as large as one bit, so your number gets bigger when you convert bytes to bits and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
What is 500 B in bits?
500 B = 4,000 bit (since 500 × 8).
What is 15 B in bits?
15 B = 120 bit (since 15 × 8).
What is 75 B in bits?
75 B = 600 bit (since 75 × 8).
How many decimals should I keep when converting B to bit?
Match the precision of your original measurement. For example, 80 bit rounds to 80 bit at 3 significant figures; keep more digits only for engineering or scientific work.
