freezingDaniel I discovered that the conversion from seconds to minutes leads to incorrect results. I have not tested much further but it seems to be related to some values of 18*10n adding one second or the few other changes I tested seem to work as expected. 180000s=3min 180s=30min
Arlo Wolframalpha Responses default empty conversions to 1, for the case celsius to kelvin this gives the wrong value (ie searching Celsius to Kelvin should give 273.15 but gives 274.15 as it puts the placeholder value of 1 in for "empty" conversions)
