What the Data Transfer Rate Converter does
This tool converts between network speed units, which is the easiest way to see what your internet plan really means for downloads. It covers bit-based rates (kbit/s, Mbit/s, Gbit/s) and byte-based rates (KB/s, MB/s, GB/s), so you can turn a connection advertised in Mbps into the MB/s your download manager shows.
How to use it
- Enter the rate in the Value box.
- Pick the unit you have in the From row (for example Mbit/s).
- Your rate appears in every other unit instantly below, with nothing to click.
- Tap any unit (for example MB/s) to copy its value to your clipboard.
Bits versus bytes
The big gotcha is bits versus bytes. Internet providers quote bits per second (Mbps), while files and download tools use bytes per second (MB/s), and there are 8 bits in a byte. That is why a 100 Mbps line tops out near 12.5 MB/s. This converter keeps the two straight, and since the math runs in your browser, nothing you type is ever sent to a server.
Frequently asked questions
- Why is my 100 Mbps connection only about 12 MB/s?
- Network speeds are quoted in bits per second, but file sizes are in bytes, and 1 byte is 8 bits. So 100 Mbps divided by 8 is about 12.5 MB/s. This converter handles that split for you.
- Which units does it cover?
- Bits per second up to gigabits per second (bit/s, kbit/s, Mbit/s, Gbit/s) and bytes per second up to gigabytes per second (B/s, KB/s, MB/s, GB/s).
- Is my data uploaded?
- No. The conversion runs in your browser, so nothing you enter leaves your device. No account, no limits.
