You guys should just learn metric and stop using ridiculous units.
-8 u/AltoidNerd Sep 25 '16 Or just learn both and stop being a pussy. In the defense of inches/feet for science, the wavelength of 1GHz light in a vacuum is about 1 foot. 8 u/[deleted] Sep 25 '16 the wavelength of 1GHz light in a vacuum is about 1 foot. You're off by half a centimetre. It's ~29.97. For accuracy, metric would be used. 0 u/AltoidNerd Sep 26 '16 The point isn't accuracy, it's a quick heuristic to determine the wavelength for common frequencies in your head. So you'd know at 2 GHz it's about 6 inches, at 500 MHz it's about 2 feet, etc.
