These are the things I wish were programmed into my brain before leaving the states, and would calculate automatically…
Celsius to Fahrenheit
°C * 9/5 + 32 = °F
Kilometers to Miles
km x 0.6214 = mi.
Kilograms to Pounds
kg * 2.2 = lbs
Milliliters to Ounces
I'm not even going to put this formula here because ounces has always been a bizarre measurement and it means nothing to me anyway, so take that, ounces.
Kilometers per Hour to Miles per Hour
kph / 1.609 = mph (or kph * 0.622 = mph)
I wonder how long it'll be before I start thinking in these measurements without having to do the conversion. Is that like when you're learning a new language and then magically at some point you start thinking in the new language? Seems like a long ways away.
