Convert Megabyte to Megabit per Second (MB → Mbps)

Converting megabytes to megabits per second is straightforward: multiply by the conversion factor. Follow these three steps to do it by hand or in your head.

1. 1
   Take your value in megabytes

   Start with the number of megabytes (MB) you want to convert.
2. 2
   Multiply by 8

   The conversion factor from MB to Mbps is 8. Multiply your value by this number.
3. 3
   Read the result in megabits per second

   The result is your value in megabits per second (Mbps).

Multiply the value in megabytes by 8. For the reverse direction, multiply by 0.125.

• ✓SI: 1 MB = 1000 KB = 1,000,000 B.
• ✓Binary MiB = 1,048,576 B — 4.86% larger.
• ✓HD drives, networks, SSDs: SI MB.

• ✗Mixing MB and MiB without noting the difference (~5%).
• ✗Confusing MB (storage) with Mb (megabit, 1/8).
• ✗Assuming 1 GB = 1000 MB always — correct in SI; binary it's 1024.

What is the Megabyte?

The megabyte (MB) equals 1,000 kilobytes (1,000,000 bytes decimal, or 1,048,576 bytes binary as MiB). It is the everyday unit for image files, MP3 songs, and small documents on personal computers. A high-quality JPEG photograph is 2–10 MB, an MP3 song is 3–10 MB, a Microsoft Word document might be 0.05–5 MB, and a typical e-book is under 5 MB. Older USB flash drives and CDs hold hundreds of MB (a CD is 700 MB). Mobile data plans were originally measured in MB before gigabyte plans became standard. The megabyte relates to the kilobyte (1,000 KB = 1 MB), the gigabyte (1,000 MB = 1 GB), and the megabit (1 MB = 8 Mbit). Internet connection speeds are usually rated in Mbps (megabits per second), distinct from MBps (megabytes per second): 100 Mbps = 12.5 MBps.

What is the Megabit per Second?

Megabits per second (Mbps) is the standard unit for internet speeds, network bandwidth, and ISP connection ratings. Note: Mbps is megabits, not megabytes — the ratio is 8 bits per byte, so 100 Mbps = 12.5 MB/s download speed. Modern broadband home connections typically offer 100–1,000 Mbps download speeds, fiber-optic connections reach 1,000–10,000 Mbps (1–10 Gbps), and mobile 5G networks deliver 100–1,000+ Mbps. Internet streaming services recommend minimum speeds: HD video needs about 5 Mbps, 4K video needs 25 Mbps, and competitive online gaming benefits from 30+ Mbps with low latency. The Mbps relates to the megabyte per second (1 Mbps = 0.125 MB/s), the gigabit per second (1 Gbps = 1,000 Mbps), and the kilobit per second (1 Mbps = 1,000 kbps). The ITU and IEEE standardize network protocols using Mbps and multiples.
