Mbps to MB/s Converter (Megabits to Megabytes per Second)

Convert internet speed in megabits per second (Mbps) to download speed in megabytes per second (MB/s). Divide by 8: a 100 Mbps plan downloads at up to 12.5 MB/s, and gigabit (1,000 Mbps) at 125 MB/s.

Step-by-Step Mathematical Explanation

Formula: Value (MB/s) = Value (Mbps) × (1,000,000 ÷ 8,000,000)
  • Step 1: Convert 100 Mbps to the base unit (bit/s): 100 × 1,000,000 = 1.0000E8 bit/s.
  • Step 2: Convert base bits per second to megabytes per second: 1.0000E8 ÷ 8,000,000 = 12.5 MB/s.
  • Direct factor: 1 Mbps = 0.125 MB/s.

Mbps to MB/s formula

Direct Answer: 1 Mbps = 0.125 MB/s, so multiply by 0.125: MB/s = Mbps × 0.125. Going back: Mbps = MB/s × 8.

How to convert megabits per second to megabytes per second

Internet providers sell speed in bits (lowercase b, Mbps); browsers, Steam and download managers show bytes (uppercase B, MB/s). A byte is 8 bits, so MB/s = Mbps ÷ 8. Real-world downloads are 5–10% lower again because of TCP/IP and Wi-Fi overhead; 940 Mbps is a typical best case on a gigabit line.

1. Mbps → MB/s

Multiply the number of megabits per second by the conversion factor:

MB/s = Mbps × 0.125

Example: 100 Mbps × 0.125 = 12.5 MB/s.

2. MB/s → Mbps

To go back, divide by the same factor, or multiply by its reciprocal, 8:

Mbps = MB/s ÷ 0.125

Example: 12.5 MB/s ÷ 0.125 = 100 Mbps.

Download time shortcut

Seconds to download = file size in MB × 8 ÷ speed in Mbps. For gigabytes, multiply the GB by 8,000:

seconds = MB × 8 ÷ Mbps

A 50 GB game on 200 Mbps: 50 × 8,000 ÷ 200 = 2,000 s ≈ 33 minutes.

Frequently Asked Questions

What is 10 Mbps in MB/s?

10 Mbps is 1.25 MB/s (10 × 0.125).

What is 1,000 Mbps in MB/s?

1,000 Mbps is 125 MB/s (1,000 × 0.125).

Why is my download speed 8 times lower than my plan?

It is not lower, just in different units. Your plan is in megabits (Mbps); your download manager shows megabytes (MB/s). 100 Mbps = 12.5 MB/s.

What about MiB/s?

Some apps (Windows, qBittorrent) use binary units: 1 MiB = 1,048,576 bytes. 100 Mbps = 12.5 MB/s = 11.92 MiB/s. Pick MiB/s in the converter to match those apps.
