How to Convert Megabits to Bytes
To convert megabits to bytes, divide by 8 then adjust for scale. Since 1 byte = 8 bits, this conversion translates bit-based measurements to the byte-based units used for storage capacity. See also: Bytes to Mb.
Mb measures data in bits—commonly used for memory addressing and low-level data specifications. See also: how many YB in Megabits.
B measures data in bytes—the standard unit for file sizes, storage capacity, and what you see in file explorers. Related: how many Bytes in a ZiB.
1 Mb = 125,000 B (using SI decimal standard) — which means there are 125,000bytes in every megabit.
Mb to B Conversion Formula
// Convert Mb to B
B = Mb × 125,000
// Reverse: Convert B to Mb
Mb = B × 0.000008
Mb to B Conversion Examples
100 Mb = 12,500,000 B
256 Mb = 32,000,000 B
500 Mb = 62,500,000 B
1,000 Mb = 125,000,000 B
2,048 Mb = 256,000,000 B
What Is a Megabit?
A megabit is 1,000 kilobits or 1,000,000 bits. Standard unit for internet connection speeds. Learn more: calculate Pb to TB.
The megabit is a SI decimal bit unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Use our TB/s to KiB/s conversion rate.
Common uses: Internet speeds (Mbps), video streaming bitrates, network bandwidth Use our converting Megabits to Exabytes.
1 Mb = 1 × 10⁶ bits = 125,000 bytes.
The megabit can be abbreviated as Mb; for example, 1 megabit can be written as 1 Mb.
What Is a Byte?
A byte consists of 8 bits and is the standard unit for measuring digital storage. One byte can represent 256 different values (0-255). See also: Zettabytes in Bytes.
The byte is a fundamental unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Related: KB to nibble.
Common uses: File sizes, memory addressing, character encoding (ASCII, UTF-8) Use our Mibps to Pbps converter.
1 B = 8 bits = 1 bytes.
The byte can be abbreviated as B; for example, 1 byte can be written as 1 B.

💡 Storage Engineer Tip
Remember: 8 bits = 1 byte. When your ISP advertises "100 Mbps," divide by 8 to get your actual download speed in MB/s (approximately 12.5 MB/s theoretical maximum).
