Convert Between Internet Speed Units Instantly
Confused why your 100 Mbps internet downloads files at only 12.5 MB/s? This converter explains the difference and instantly converts between megabits per second (Mbps) and megabytes per second (MB/s). Essential for understanding real download speeds.
Understanding Mbps vs MB/s
Internet Service Providers (ISPs) advertise speeds in Mbps (megabits per second), but your computer shows download speeds in MB/s (megabytes per second). Since 1 byte = 8 bits, you divide Mbps by 8 to get MB/s. That's why 100 Mbps equals only 12.5 MB/s.
Conversion Formula
MB/s = Mbps ÷ 8 | Mbps = MB/s × 8Why This Conversion Matters

How to Use the Converter
Common Use Cases
Verifying ISP Speed
If you pay for 500 Mbps, speed tests in MB/s should show ~62.5 MB/s.
Gaming Downloads
A 100 GB game on 100 Mbps takes about 2.2 hours (100,000 MB ÷ 12.5 MB/s).
Streaming Requirements
4K streaming needs 25 Mbps (3.125 MB/s), 1080p needs 5 Mbps (0.625 MB/s).
Cloud Backup Planning
Calculate upload times using your upload speed in Mbps converted to MB/s.
Frequently Asked Questions
Using megabits makes speeds appear 8x larger. 100 Mbps sounds faster than 12.5 MB/s, even though they're the same speed. It's a marketing convention that stuck from early telecommunications.
