Data Transfer Rate Converter
Convert bps, Kbps, Mbps, Gbps, and MB/s.
Bits, bytes, and speeds
Network speeds are quoted in bits per second while files are measured in bytes, and the factor of eight surprises people: a 100 Mbps line tops out near 12.5 MB/s of actual download.
It settles the 'why is my gigabit connection only downloading at 120 MB/s' question instantly, since dividing the bit rate by eight gives the byte rate you actually see in a download manager.
Bits vs bytes
Watch the case — Mb is megabits, MB is megabytes. The converter keeps them straight, and all math runs locally in your browser. Your values are converted locally and never uploaded.
Frequently Asked Questions
How does the data transfer rate converter work?
Rates are normalized to bits per second. 100 Mbps is 12.5 MB/s because there are eight bits in a byte.
When should I use this converter?
Use it for internet plans, download estimates, video workflows, server throughput, and comparing megabits with megabytes.
What is the main limitation?
Real transfer speed can be lower because of protocol overhead, Wi-Fi conditions, and storage write limits.
Is this converter private?
Yes. The conversion runs entirely in your browser, so your values are not uploaded, stored, or sent to a server.
