    ‘How much energy does it take to boil a room-temperature gallon of water?’

    This is a question I’ve never once heard asked outside of a chemistry lab. Which is where metric units are useful.

    These supposed facts are also not true except with distilled water, at sea level, etc. etc. Water doesn’t freeze at 0°C, it requires activation energy. And any impurity will lower its freezing point. Plenty of ocean water at well below 0°C, as well as fresh water at very high pressures.

    A bottle of wine is 750ml (or 75cl) and a pint (i.e. a normal glass) is 0.4731765L. Very intuitive.

    What’s the efficiency of an ICE motor in metric? L/100 km? Great that it can be converted into other units, but it’s existence an admission that it’s not a useful human-centric measurement. Just like air temperature. When I switch my car to metric, the thermostat has to add a digit and increment in half degrees to give you what Fahrenheit gives you without a third digit. The external air temperature requires a sign in metric.

    Also, which US state did Dr. Fahrenheit hail from? I’ll give you one guess.

    But hey, decimalization is great, right? So why don’t you use metric time? Come on, throw away a lifetime of knowledge and compatibility with others because it can be converted easier in your head.

      This is stunningly arrogant and ridiculously incorrect at the same time.

      Do you not understand? Or do you not want to understand?

      If you really want to understand, I will explain everything and show you how deeply wrong you are. However I will not spend time explaining, if you will then still continue with this “I am used to this system so everyone else must be wrong.” approach.

      But if you like being wrong I recommend you at least not publicly announcing it.
