Internet and network speeds are marketed in bits per second (Mbps, Gbps), but file sizes and download progress bars are almost always shown in bytes. Since one byte equals eight bits, an advertised "100 Mbps" connection tops out around 12.5 megabytes per second, not 100 — a mismatch that trips up a lot of people.
This converter handles both the bit-based network-speed units and the byte-based download-speed units in one place.
How it works
Enter a data rate, choose the unit you're converting from, and the unit you want to convert to. The tool applies the standard bit/byte and metric-prefix scale factors and returns the result.

Examples
Estimating a real download speed
A 200 Mbps internet plan converts to 25 megabytes per second — the number a download manager would actually show.
Who should use it
- Estimating real-world download time from an advertised internet plan speed.
- Converting network throughput specs between different reporting conventions.
Industry applications
- Internet service and telecommunications
- IT and network administration
Advantages
- Covers both the bit-based units used for marketing network speeds and the byte-based units used for actual file transfer.
- Clarifies the common bits-vs-bytes confusion directly in the conversion.
Common mistakes to avoid
- Assuming an advertised Mbps internet speed directly equals the megabytes-per-second figure shown in a download manager.
- Confusing this rate converter with a storage-size converter — they measure fundamentally different things.
Best practices
- When estimating download time for a file, convert your connection's Mbps rating to megabytes per second first, since file sizes are almost always listed in bytes.
Tips
- Divide an advertised internet speed in Mbps by 8 to get a rough megabytes-per-second estimate — a quick mental shortcut for gauging real download speed.
