How do I convert 245 KiB/s / Is this any good?

How do I convert 245 KiB/s to kbps? / Is this any good?

Hi all. I've got Gnome System Monitor reporting 245 KiB/s? How do I convert it to mbps,or whatever it is in English. ie I have BT infinity and used to get a 16 mbps whatever the units are. is 245 KiB/s any good?

Downloading Ubuntu Studio, the big dvd. Came out today, so I thought the servers would be slow. Am getting a constant 245 KiB/s and has been going for hours. Is this any good? I've got the cheapest broadband package that BT do, 4o gig / month. It's about £36 / month, I can't remember exactly. It really isn't a lot of money, and I can't be arsed to go through all the paperwork to find an exactl figure. Had to say that so don't get all the smartarses giving me formula for kBps and kbps etc I cannot remember exactly, and the smartarses saying thatis is pisspoor etc, compared to what you would get, for example, if you lived next door to the exchange paying the max performance package you could buy etc

Aha, tia from Alex.

A kibibyte (kiB) is 1024 bytes
A kilobyte (kB) is 1000 bytes

A mebibyte (MiB) is 1024 x 1024 bytes *Note the capital M
A megabyte (MB) is 1,000,000 bytes

And a Byte is 8bits.
Old style line speeds are quoted as x bits/sec - but when translating to data speeds in Bytes/sec then you have to add in protocol wrapping, so reckon 1Byte = 10 bits

16mbps seems quite slow for BT infinity, which I thought was the new super-fast fibre cable connection.

I have a theoretical 20mbps copper cable line-speed connection which gives me a very reasonable 17mbps actual download speed. When downloading big files such as a ubuntu.iso I use torrent if possible and regularly get d/l speeds of very close to 2 megabytes/second which I sometimes check with vnstat.

It seems to me therefore that your quoted 245 KiB/s is slow for your connection and may simply be due to the servers being extremely busy. For comparison, my d/l speed max is about 7 or 8 times faster than yours, assuming you have mentioned the figures correctly.
Xubuntu 12.04 user, and loving it!

1 Ki = 1 k
1 B = 8 b
/s = ps

245 KiB/s = 1,960 kbps
or, a shade short of 2 Mb.

Yes.

1 Ki = 1 k


Not correct.

1 ki (or Ki)= 1.024 k

Except that k often indicates 1,024 making 1Ki = 1k.

Different standards have been proposed at different times. The industry pretty much ignores them.

Then again, does the B mean bytes at the network layer or bytes at the data layer?

I know, let's have a technical discussion and completely baffle the poor OP. :wink:

This business of how many bytes in a Kilo byte is something akin to how many "thous" in an inch.
People will say a thousand, but how many of these people have taken the time to count them. I have long contended that bytes, just like thous must be of slightly different sizes and therefore the number must vary.
On a cold winters day all those little thous will huddle up against each other for warmth, and so at a time like that there must be quite a few more than a thousand.
It must be a similar situation with bytes.
Oh, sod it.
