0.125

Conversion formula

Forward

bytes = bits × 0.125

Reverse

bits = bytes × 8

Example: 10 b × 0.125 = 1.25 B.

About both units

From

Bit

The bit is the smallest unit of digital information — a single 0 or 1. Coined by John Tukey in 1946. Network speeds, modem rates and compression ratios are measured in bits; file sizes and memory in bytes (8 bits each).

Real-world: Home fibre: 100 Mbps = 100,000,000 bps. AES key: 256 bits. MP3 bit rate: 128–320 kbps.

Byte

The byte equals 8 bits — the basic unit of file size and memory. One byte encodes one ASCII character. All file sizes and RAM capacities are quoted in bytes and their multiples (KB, MB, GB, TB).

Real-world: An ASCII character: 1 byte. A short text message: few hundred bytes. Uncompressed photo: few MB.

500,000 b	62,500 B

Tips & common mistakes

Quick tips

8 bits = 1 byte.
Mbps ≠ MB/s — divide by 8 to get bytes per second.
Encryption strength often given in bits (128, 256).

Avoid these

Mixing b (bit) and B (byte) — 8× difference.
Thinking a 1 Gbps link delivers 1 GB/s — it's 125 MB/s.
Reading "256-bit encryption" as "256-byte" — totally different strength.

Frequently asked questions

How many bytes in a bit?

One bit equals 0.125 bytes.

How do I convert bits to bytes?

Multiply the bit value by 0.125 to get the equivalent in bytes.

What is 100 bits in bytes?

100 bits equals 12.5 bytes.

Is a bit bigger than a byte?

No. 1 bit equals 0.125 bytes, so one bit is smaller.

How to convert bits to bytes without a calculator?

Multiply by 0.13 for a quick estimate; use a calculator for precise results.
