# Numbers

These options decide what DU Meter's numbers show, wherever they are: in the DU Meter window, on the taskbar,
floating, or in the Windows 10 taskbar band, and the units of every figure DU Meter shows.

### What the numbers show

**Speed, averaged over** a number of seconds: the download and upload speeds. This is the default.

**Received and sent this billing period**, or **Cost this billing period**: what has been transferred, or what it
has cost, since the period began. These need a billing period, set up with
[data transfer costs](https://www.hageltech.com/support/kb/du/using/options/costs).

**Show the usage card when pointing at the numbers**: the card shows today's and this month's usage and, with
a [data limit alert](https://www.hageltech.com/support/kb/du/using/options/long_alert) set, how much of the limit is used. Out of the graph window it
also lists the programs using the network. A click on the numbers always shows it.

**Keep the numbers clear of the taskbar's buttons**: numbers on the taskbar move aside when its buttons need the
room, and go back to where you put them once the room is free again. When the taskbar has no room for them at
all, they wait just beside it. Turn this off to have the numbers stay exactly where you put them, even over
buttons, or if they behave oddly on your taskbar.

### Units

**Speeds in**: bytes per second (KB/s), handy for comparing with the size of a file, or bits per second (kbps),
the unit connection speeds are sold in.

**Sizes as**: KB, MB, the abbreviations most people know, or KiB, MiB, as the IEC 60027-2 standard writes
multiples of 1024. See [Units of measurement in DU Meter](https://www.hageltech.com/support/kb/du/units).
