Does anyone know how to convert bandwidth figures
Like if your using 50 MB's a second
how many gigs is that a month and how many Terabytes is that a month

50mb x 3600seconds = 180000
180000 x 24h = 4320000 4320000 x 30 days = 129600000mb 129600000mb = 123.596191 terabytes http://www.t1shopper.com/tools/calculate/ it's like a tv live stream |

MB or Mbit?
50x*60*60*24*31/1000 50x*60*60*24*31/1000000 where x = MB or Mbit. The answer will be in MB or Mbit as you define the x. That would be my guess and it ignores the nerdy difference between a megax and 999800x or whatever the real number is. CD34 will be by soon to tell you the real way of doing it instead of my backwoods hick way.

Try dividing it by 8 and see if that looks more like the number you were expecting. 8 bits to a byte, and most connection speeds are measured in bits, not bytes.

Roughly 320gb (monthly) to the MBPS - so call it 16,000 gigabytes or 16 terabytes

According to Google: 1 month = 2,629,743.83 seconds
So, 50 MB x 2,629,744 = 131,487,200 MB Getting google to again do the math: 131,487,200 megabytes = 125.395966 terabytes Tommy, pclit is correct! |

The easiest way as stated above is the 320GB per megabit calculation. 50 * 320 = 16000 / 1000 = 16 terabytes.

If there is nobody out there, that's a lot of real estate going to waste!

Maybe a shade less if they are using 8+1 bits per byte.

I stand corrected. Actually, I am sitting. Thanks for setting me straight.

The above calculations would only be valid if you used exactly 50 Mbps all
month, with no busy times and no slow times, or if you AVERAGED 50 Mbps. But Mbps isn't normally measured as an average, so you can't just calculate it by multiplying by the number of seconds. Rather, bandwidth is measured by either peak or 95th percentile. Normally, bandwidth is billed under a formula called 95th percentile. Every five minutes or so the average Mbps for that 5 minute block is recorded. At the end of the month, all of the numbers are sorted from highest to lowest. The highest five percent are thrown out, and you are billed for the highest number remaining. That's generally going to be about double your average Mbps, so figure 8 TB rather than 16 TB if you're asking how many TB you can transfer and be billed for 50Mbps. That figure depends on how your traffic varies throughout the day and throughout the month, though. For typical web traffic, divide the TB in half or double the Mbps. If you're talking about something other than web traffic the factor could be very different. Bandwidth can also be measured peak, such as when talking about a 10Mbps or 100 Mbps ethernet connection. A 100 Mbps line can carry no more than 100 Mb in it's busiest second. Figure your average is around 1/3rd of your peak, so if you're doing 16TB you'll peak out at about 150Mbps. If you decide it's OK for the site to be just a little slow during it's busiest times, you could run a site pushing 16TB on a 100Mbps line. The site would just be a bit slow during it's busiest times, when it would use 150 Mbps if it could. In the paragraph mentioning the 100 Mbps, I actually ignored one important factor. 100Mbps or other line speeds are signaling rates, not data transfer rates. The electrical signal can switch on and off 100 million times per second, but due to protocol overhead it can only transfer about 86Mb of data per second. So a 100 Mbps line is really a 86 Mbps line in terms of the amount of data it can move. |
