Someone came back with the figure of just under 41 GB.
Forget that figure. As I pointed out in that thread, that guy forgot there were 8 bits in a Byte. Notice 41/8 Gb = 5.125 GB = about your calculation.
Google has only given you the amount in GB of the transmission data. This is not the same as the amount of digital storage data seen by your PCs for 2 reasons:
- For transmission data 1 K = 1000, but conventionally for digital storage on PCs 1 K = 1024, altho' strictly speaking the use of 'K' is not the international standard for this unit but it should be 'Ki'.
- Not all transmitted data reaches your PCs (throughput) cuz of the protocol & routing overheads carried by it. My rule of thumb on ADSL is that actual throughput is 5/6th of transmitted data
So, to be exact:
42,698,775 Kilobits = 42,698,775,000 bits = 5,337,346,875 Bytes of transmission data (as per Google)
= 5,337,346,875 * 5 / 6 Bytes = 4,447,789,063 Bytes of digital storage data (the throughput)
= 4,447,789,063 / (1024*1024*1024) = 4.142 GigaBytes of digital storage data.
However as pointed out the counters kept by the router are limited in their capacity & therefore cannot be trusted. You'd be better off getting a network metering program on your PCs for your purpose.
