Data Transfer Rate Converter
Convert between bits and bytes-based data transfer rates — bps, Mbps, MB/s, GB/hour — with a real-world download time example. Runs entirely in your browser.
🔒 This tool runs entirely in your browser. Your files are never uploaded to a server.
- Mbps
- MB/s
- GB/hour
- 1GB file in
How it works
- Enter a speed and its unit.
- See it converted to Mbps, MB/s, and GB/hour instantly.
- Check how long a 1GB file would take at that speed.
The formula
Every unit is converted to bits per second first, using decimal (1000-based) prefixes:
MB/s = Mbps ÷ 8
FAQ
Why is my download speed in MB/s so much lower than my Mbps plan?
Internet plans are advertised in megabits per second (Mbps), but download managers usually show megabytes per second (MB/s) — there are 8 bits in a byte, so a 100 Mbps plan tops out around 12.5 MB/s.
Does this use 1000 or 1024 for kilo/mega/giga?
Decimal (1000-based) — the network-standard convention used for bandwidth, matching how ISPs advertise speeds. This differs from the binary (1024-based) convention sometimes used for file sizes.
Is my data uploaded anywhere?
No — every conversion happens locally in your browser.
