Data transfer converter
Connection speeds — where bits and bytes get mixed up. 7 units, converted from one table of exact factors.
—
1 megabit/second in every other data transfer unit
Computed by the same engine that runs the converter above, so these can never drift apart from it.
| From | Equals | Unit |
|---|---|---|
| 1 megabit/second | 1,000,000 | bit/second (bit/s) |
| 1 megabit/second | 1,000 | kilobit/second (kbit/s) |
| 1 megabit/second | 0.001 | gigabit/second (Gbit/s) |
| 1 megabit/second | 125,000 | byte/second (B/s) |
| 1 megabit/second | 125 | kilobyte/second (kB/s) |
| 1 megabit/second | 0.125 | megabyte/second (MB/s) |
What each unit actually is
Most converters give you a number and stop. Where a figure is exact by definition we say so, and where it is an average or shifts with conditions we say that too — that is usually the thing you needed to know.
| Unit | Symbol | What it actually is |
|---|---|---|
| bit/second | bit/s | |
| kilobit/second | kbit/s | |
| megabit/second | Mbit/s | What broadband is advertised in. |
| gigabit/second | Gbit/s | |
| byte/second | B/s | Eight bits. This is the one download managers show. |
| kilobyte/second | kB/s | |
| megabyte/second | MB/s | A 100 Mbit/s line downloads at about 12.5 MB/s — the factor of 8 is why the advertised number never matches the progress bar. |
