Neat, although it's buggy in Fahrenheit. It opens for me in Fahrenheit, maybe based on my browser's locale or geoip. The page opens with initial temperature 4; selecting fridge changes it to 4; selecting room temp changes it to 21. Those numbers make much more sense in Celsius! And indeed if I change the scale to Celsius, it uses those same numbers, now representing very different temperatures. This makes a significant difference: with a US L egg at sea level, soft boil time is 8 minutes 27 seconds from the fridge in Fahrenheit, 6 minutes 58 seconds in Celsius. In my experience, the right answer is 6 minutes even, though opinions about runniness vary... (Sending a note about this to feedback@omnicalculator.com) edit: also, it says US L egg = 60 g? That's not right, unless maybe they're counting the shell, which they shouldn't. 50 g is about right and what cronometer.com says. cronometer also says 56 g = extra large, 63 g = jumbo.
