I’ve talked about the clever calculator features built into Google before. Most of my examples then were rather silly. Well I’ve started using it a bit more seriously recently. The great thing it does is allow unit conversions to be done effortlessly at the same time as the main calculation.
For example, I have a video clip that is about 350 MB and 45 minutes long. I want to know what the average bit rate for the encoding is, in kbps. 350 MB is 350 * 1024 * 8 kbits. 45 minutes is 45 * 60 seconds. Works those two out, divide the first by the second and I have my answer. Or just type
350 MB / 45 minutes in kbps into Google and I have my answer with far less effort.
