I typically use google for most unit conversions. How much concrete do I need for my driveway? I type this at the top of Chrome: 1/4 mile * 8ft * 4in in yd^3

- Cerium 6y agoMy favorite Google unit query: "the speed of light in ghz*in". The answer is the interesting and useful 11.8028527. Interesting because if you have not studied microwaves, you might not even know that as a unit for the speed of light, useful because it makes clear the relationship between wavelength and antenna length. Divide to cancel frequently and you have wavelength.

- Cerium 6y agoThanks for sharing, I had never heard this before.
- ConceptJunkie 6y agoThis is the same as inches per nanosecond, which is a little more intuitive for us non-antenna-designers.
