Bits vs bytes, in plain English
- 1 byte equals 8 bits. That single rule connects every result on this page. To convert a bit rate to a byte rate, divide by 8.
- ISPs sell bandwidth in megabits per second (Mbps). Browsers, file managers, and download dialogs report progress in megabytes per second (MB/s). A 100 Mbps plan tops out at 12.5 MB/s in real-world download speed.
- SI units (kbps, Mbps, Gbps, MB/s, GB/s) use base 10. Each step is 1000 times the previous. RAM and some file system tools use IEC units (MiB/s, GiB/s) which are base 2 and each step is 1024 times the previous.
- Protocol overhead, latency, and Wi-Fi conditions mean real-world transfer speeds usually come in below the theoretical maximum. The numbers shown here are the exact unit conversion, not an end-to-end speed prediction.

How to use
- Type a number into the input. You can paste with a unit suffix (for example '100 Mbps' or '12,5 MB/s') and the tool will parse it.
- Pick the source unit from the three family panels: bits (kbps, Mbps, Gbps), bytes (KB/s, MB/s, GB/s), or binary bytes (KiB/s, MiB/s, GiB/s). The matching card highlights in blue.
- Read the headline conversion card for the best-fit bit unit and best-fit byte unit, then scan the per-family result columns for every other unit.
- Use the Show units filter to focus on bits only, bytes only, or binary bytes only when you do not need the other families.
- Adjust decimal places (0, 2, 4, or 6) for the precision you need, or click Copy on any card to grab a single converted value. Tap a Common reference speed to load it instantly.
About this tool
Data Rate Converter turns one bandwidth or transfer-speed number into every other common unit at once. ISPs sell internet plans in megabits per second (Mbps), web browsers and file managers report progress in megabytes per second (MB/s), mobile networks use kilobits per second (kbps), backbone links are sized in gigabits per second (Gbps), and RAM bus speeds use the binary mebibyte family (MiB/s). The tool covers three parallel families so you never have to remember which one a given vendor uses: bit-based SI (bps, kbps, Mbps, Gbps, Tbps), byte-based SI (B/s, KB/s, MB/s, GB/s, TB/s), and byte-based IEC (KiB/s, MiB/s, GiB/s, TiB/s). All conversions go through a single canonical bits-per-second value, using the standard rule of 8 bits per byte, so the math is exact within double-precision rounding for every realistic bandwidth. Quick presets cover the searches people actually run (100 Mbps to MB/s, 1 Gbps to Mbps, 25 Mbps to MB/s for 4K streaming, 5 Mbps to kbps), and the input accepts free-form values like '100 Mbps' or '1,5 Gbps' with case-insensitive suffix parsing. If you type a suffix that does not match the selected source unit, a one-click swap appears so you cannot silently get the wrong reading. A reference panel lists common real-world speeds (dial-up, 3G, DSL, SD/HD/4K streaming, fiber, Wi-Fi 5/6, USB 3.0, Thunderbolt 4, 10 GbE, 100 GbE) and one click loads any of them as the canonical bps so you can see how every unit names that exact speed. Useful when you want to know how fast a 1 Gbps fiber plan really downloads in MB/s, sanity-check an ISP speed test, compare router throughput to a streaming bitrate, or translate a Wi-Fi spec into the units a download dialog will show. Everything runs in your browser, so nothing you type is sent anywhere.
