      90-110 is hand washing temp. 100 average.

      110 is hot

      120 recommend max

      130 very hot

      140 very very hot

      150 burns

      If I said to you. Would you stick your hand in 50°C water for 100 dollars would you do it?

      What about 60°C?

      65°C?

      I bet you don’t know what would happen if you stuck your hand in 65°C water without looking it up. There’s a huge jump from 60° to 65°C. 70°C will instantly scald you.

      Someone out there is stupid enough to think. Water boils at 100°C, 65 should be perfectly fine. Even though water doesn’t boil until 212°, most people would be cautious of sticking their hand in 100°F+ water.

      Yes if you think 40°C+ is hot then you can gather that 65°C would be hotter. But why compare to 40° when you can do 100°.

        Why compare it to 40°? Because I know what 40° feels like because I’ve been living in a civilized country with a civilized measurement system all my life. I can tell you that 65° is too hot, because I make my tea with 70° to 80° hot water. Therefore just before that will probably be too hot for my skin.

        In the end, there is no objectively better system when it comes to day to day temperatures. But there is one when it comes to science, reliability and universality and that is Celsius.

        All international science uses metric and slowly but surely the resistance amongst US universities melts away and they switch to metric as well. Give it another one or two generations and we’ll finally be rid of the outdated and arbitrary imperial system!
