CORRECTION OF BAROMETER READINGS TO 0°C TEMPERATURE
The following corrections are ud to reduce the reading of a mercury barometer with a brass scale to 0°C. The number in the table should be subtracted from the obrved height of the mercury column to give the true pressure in mmHg (1mmHg = 133.322 Pa). The table is calculated from the formula
∆h = -0.0001634 ht/(1+0.0001818 t),
where h is the obrved column height in mm and t the Celsius temperature. This relation is bad on thermal expansion coefficients of 181.8·10-6°C-1 for mercury and 18.4·10-6°C-1 for brass.
