>a 6ft wave is under 2 m and we would not call a wave 182.88 cm This is subjective but we call it 1.8m and I don't really see a problem "seeing" it visually. 1.8 is just a bit above my eye level. >Fahrenheit is also more precise You could use a C2 scale where C2 = Celsius*2. >it’s best to use a temperature gauge that’s suited to the air I believe neither Celsius nor Fahrenheit alone can tell you how "hot" the weather is. So the advantage argued is not very valid: Air temperature does not give a full picture of "hotness", we have to also include humidity ( that's why weather reports usually have a "feels-like temperature" next to air temp ). This is where we use the Wet Bulb temperature [1] to describe the sense of hotness in our surrounding. Wet Bulb Temperature can tell you the rate at which your body can cool itself.

The Wet Bulb temperature still needs a unit of measurement. > Even heat-adapted people cannot carry out normal outdoor activities past a wet-bulb temperature of 32 °C (90 °F), equivalent to a heat index of 55 °C (130 °F) So the F wet bulb temperature seems to make even better use of 2 digit readings than "plain" F. With 2 digits, C only uses 32% of the possible 2-digit readings. I couldn't find anything for the low end...

  The Wet Bulb temp can use any scale they see fit, it's a derived unit. It's even better if they don't use F and C to avoid confusion.

    > The wet-bulb temperature (WBT) is the temperature read by a thermometer covered in water-soaked cloth (wet-bulb thermometer) over which air is passed It seems to be a direct measurement, not derived from anything. You might be able to derive WBT given the dew point and dry bulb temperature, but it would still need units like C or F. Perhaps you were thinking of a different measurement?

      I believe that's a shortcut to measure WBT directly. By it's nature, WBT are affected by other variables such as humidity and atm pressure, etc... , so it's a derived unit: Twb = F(T, H, P...). As a derived function, you tweak its scale as much as you like, you can take T = C*2 and that solved your problem.

        But surely deriving the WBT couldn't change the unit of measurement? A measurement that has no unit is relative humidity. It is just a percentage. There is no way to measure relative humidity directly and get any other type of unit besides a percentage. Instruments that measure relative humidity directly measure in percentages. edit: ah, you can use C2 = Celsius*2 whether you're talking about regular temperature or WBT. C2 is the 'derived' unit. Not WBT. Yes you can use C2, but why not just use F which still has better precision than C2[1]? For low values of C2, you may confuse it with plain C...
