Understanding the difference between Megabits per second (Mbps) and Megabytes per second (MB/s) is essential for measuring internet speeds accurately. This guide explains the conversion process in detail and provides a free, precise calculator to help you determine your actual download speeds.
Mbps to MB/s Converter
Therefore: MB/s = Mbps ÷ 8
Key Takeaways
- 1 Megabyte (MB) = 8 Megabits (Mb)
- MB/s = Mbps ÷ 8
- Internet providers advertise speeds in Mbps, but downloads are measured in MB/s
- Our converter tool provides exact calculations without rounding errors
How to Convert Mbps to MB/s (Simple Formula)
The conversion is straightforward:
Download Speed in MB/s = (Mbps) ÷ 8
Common Conversions
| Mbps | MB/s |
|---|---|
| 10 Mbps | 1.25 MB/s |
| 50 Mbps | 6.25 MB/s |
| 100 Mbps | 12.5 MB/s |
| 200 Mbps | 25 MB/s |
| 500 Mbps | 62.5 MB/s |
| 1000 Mbps (1 Gbps) | 125 MB/s |
Why Internet Providers Use Mbps Instead of MB/s
- Historical Standard – Network speeds have always been measured in bits, not bytes.
- Marketing Impact – Larger numbers (e.g., 100 Mbps vs. 12.5 MB/s) appear more appealing.
- Technical Consistency – Data transfer rates in networking are traditionally calculated in bits per second.
How It Works?
- Enter your speed in Mbps (e.g., 150, 300, 1000).
- Click “Convert.”
- Get the exact MB/s value (e.g., 300 Mbps = 37.5 MB/s).
This tool ensures no rounding errors, unlike many online calculators that approximate results.
Why Your Download Speed May Be Lower Than Expected
If your actual download speed is slower than the converted MB/s value, possible reasons include:
- Network Overhead (TCP/IP protocols reduce usable bandwidth).
- Wi-Fi Interference (walls, distance, and congestion affect performance).
- Server Limitations (download sources like Steam or Netflix may throttle speeds).
- ISP Throttling (some providers limit speeds during peak hours).
For accurate testing, use Speedtest.net (measures Mbps) and convert to MB/s using our mbps to mbs converter.

Frequently Asked Questions (FAQs)
How do I use the Mbps to MB/s converter?
Simply enter your internet speed in Mbps(e.g., 100, 200, 500) and click “Convert.” The tool will instantly display the equivalent speed in MB/s using the exact formula (Mbps ÷ 8).
Why does 100 Mbps equal 12.5 MB/s?
Because 1 Byte = 8 bits. Internet speeds are measured in Megabits (Mb), while file downloads use Megabytes (MB). Dividing Mbps by 8 gives you the true download speed in MB/s.
Is this converter more accurate than others?
Yes. Many online tools round off decimals (e.g., showing 2.88 MB/s for 23 Mbps), but ours displays exact values (2.875 MB/s) without approximation.
Why does my actual download speed not match the converted MB/s?
Real-world speeds are affected by:
- Wi-Fi interference
- Network congestion
- Server limitations (e.g., Steam, Netflix)
- ISP throttling
Can I use this tool on mobile?
Absolutely. The converter is fully responsive and works seamlessly on smartphones, tablets, and desktops.
Do I need to download anything to use this mbps to mb/s converter?
No. This is a web-based tool that runs directly in your browser—no installations or sign-ups required.
How do I test my internet speed in Mbps?
Use services like:
- Speedtest.net
- Fast.com
- Google’s speed test (search “speed test” on Google)
Then input the result into our converter.
Does upload speed follow the same conversion?
Yes. Upload speeds (also measured in Mbps) convert to MB/s the same way: Divide by 8.
Why do ISPs advertise speeds in Mbps instead of MB/s?
Two key reasons:
- Historical standards (networking always uses bits)
- Marketing (larger numbers appear more impressive)
How do I convert MB/s back to Mbps?
Multiply MB/s by 8. Example: 10 MB/s × 8 = 80 Mbps.
