Recently I was wondering how much data I transmit and receive per month over the Internet and how much that would be on average. Here's the math:

When looking at statistics at home and at work I can see that I transfer around 30 GB a month over fixed and mobile networks. 30 GB, that's 30.000 MB or 30.000.000 kByte per month. Divided by 60 seconds * 60 minutes * 24h * 30 days that results in 30.000.000 [kB/month] / 2.592.000 [seconds/month] = 11.57 kByte per second = 92.6 kbit/s.

Wow, 92 600 bits per second 24h a day, that's much more than I thought!

when you state it that way, it is very interesting. especially since it was not that long ago that you could not even get those bit rates at your house! 🙂

Only 92.6 Kbit/s? You are so narrow band! 😉
