table 2 shows an example in which the temperature offsets are positive. In this example, the reference altitude
is set at 1000 m. at 3000 m the altitude difference is 2000 m and Wristop Computer shows 80 m too little
(20 ºC * 2000 m * 0.002/ºC = 80 m). Your actual altitude is thus 3080 m.

table 2. example using meters and Celsius.
table 3 shows an example in which the temperature offsets are negative this time imperial units are used.
the reference altitude is set at 3280 feet. at 9840 feet the altitude difference is 6560 feet and Wristop Computer
shows 100 feet too much (-14 ºf * 6560 ft * 0.0011/ºf = -100 ft). Your actual altitude is thus 9740 ft.
