Fahrenheit is not only inaccurate, it is in error. Fahrenheit originally chose 96° as human body temperature. He also wanted zero to be the coldest a salt-water mixture could be before it froze. That also proved to be in error. Thus the whole Fahrenheit scale is in error.

On thinking about this, I came up with these ideas: 1 degree Celsius is about our sensitivity to temperature change. 1 litre is the capacity of an average human stomach. 1 litre of water has a mass of 1 kilogram. 1 long pace is about a metre. 1 metre is the height of a door handle. 1 metre per second is the speed of a slow walk. 1 millimetre of rain falling on 1 square metre of your roof will provide 1 litre of water in your rainwater tank. 100 metres per minute is the speed of a brisk walk. Can you help me with any more?
