	MERCURIAL - Online Information article about MERCURIAL
		The correction is generally between one and two thousandths of a degree per centimetre of mercury change of pressure, but must be determined for each thermometer, as it depends on the nature of the glass and on the form and thickness of the walls of the bulb.
		The internal pressure is greater when the mercury is rising than when it is falling, and the reading is depressed to an extent depending on the fineness of the bore and the thinness of the walls of the bulb.
		Even in the best thermometers, when there are no in-equalities of bore sufficient to account for the observed variations, it is seldom found that the mercury runs equally easily in all parts of the stem.

		a mercury thermometer or electrical meter) or are paired with an indicator (perhaps indirectly through an analog to digital converter, a computer and a display) so that the value sensed becomes human readable.
		Since a signal involves an exchange of energy, sensors can be classified according to the type of energy transfer that they detect.

		Air temperature is measured by a mercury thermometer, which uses the principle of contraction and expansion.
		When the temperature rises, the mercury expands and rises in the thermometer tube.
		The Fahrenheit scale is used in the U.S. On this scale, 32° is the freezing point of water, 212° the boiling point.

		When Celsius decided to use his own temperature scale, he chose to set the boiling point of pure water at 0º C and the freezing point at 100º C. One year later Frenchman Jean Pierre Cristin proposed an inverted version of the scale (freezing point 0°, boiling point 100°).
		Finally, Celsius proposed a method of calibrating a thermometer:
