The star's true temperature, and so the planet's surface temperature, cannot be measured with accuracy.
2.
In addition, brisk winds from the north and west will cause the air to feel even colder than its true temperature.
3.
Apparently ignorant of Daniel Bernoulli's work, he was led to the incorrect, but suggestive, relationship that expresses the product of pressure " P " and volume " V " as proportional to the square of his " true temperature ".
4.
For example, a thermometer could be calibrated so the error of indication or the correction is determined, and adjusted ( e . g . via calibration constants ) so that it shows the true temperature in Celsius at specific points on the scale.
5.
The mercury thermometer, invented before the thermodynamic temperature was understood, originally " defined " the temperature scale; its linearity made readings correlate well with true temperature, i . e . the " mercury " temperature scale was a close fit to the true scale.
6.
The results of the grey atmosphere solution : The observed temperature T _ { eff } is a good measure of the true temperature T at an optical depth \ tau = 2 / 3 and the atmosphere top temperature is 0.841T _ { eff }.
7.
:: : And, if everything is OK except that the temperature range is off, I suggest you use the oven thermometer to determine the true temperature at each setting, and either write that directly on the knob, or make a chart mapping the actual temperature to each temperature setting.
