What is the standard temperature for 11,000 feet?

Explanation:
In the International Standard Atmosphere, temperature decreases with altitude at about 2°C for every 1,000 feet up to the tropopause. Starting from 15°C at sea level, the drop for 11,000 feet is 2°C × 11 = 22°C. 15°C − 22°C equals −7°C, so the standard temperature at 11,000 feet is −7°C. The other values would be results of rounding or using slightly different lapse-rate assumptions, but the ISA value at exactly 11,000 feet is −7°C.
