bits to bytes | Exact Decimal + Formula
1 Bit = 0.125 Byte
One byte equals exactly 8 bits — a fixed ratio you can memorize. Real-world use: network speeds (bits per second) and low-level digital communication. This page expresses those values in bytes, which is used for file sizes, memory capacity, and storage specifications. Enter any value above — the result updates instantly, and a 1–1000 reference table follows below.
About Bit and Byte
Bit (b)
A bit is the smallest unit of digital information — a single 0 or 1.
Where it's used: Network speeds (bits per second) and low-level digital communication.
Byte (B)
A byte is 8 bits, the standard unit for file sizes.
Where it's used: File sizes, memory capacity, and storage specifications.

b = B × 8 Mental Math Shortcut
Divide the value by roughly 8 to quickly estimate the converted result.
Common Bit to Byte Calculations
- 5 b = 0.625 B
- 10 b = 1.25 B
- 50 b = 6.25 B
- 100 b = 12.5 B
- 500 b = 62.5 B
Precision & Practical Use
For example, 10 b = 1.25 B — roughly standard single unit scale.
Storage is sold in decimal units (1 GB = 1,000,000,000 bytes) but operating systems may report binary units (GiB). Our converter uses the decimal convention used by drive makers.

How to Convert Bit to Byte
How many bytes are in one bit?
One Bit (b) equals 0.125 Byte (B). To convert bits to bytes, multiply the bit value by 0.125.
How do I convert Bit to Byte?
Multiply your bit value by 0.125 to get the result in Byte: B = b × 0.125. For example, 5 b = 0.625 B.
What is the formula for converting b to B?
The conversion formula is B = b × 0.125. Use the calculator above for any value, and see the reference table below for common inputs from 0.001 to 1000.
Is there a quick mental estimate for b to B?
Divide the value by roughly 8 to quickly estimate the converted result.
