WebUse the formula: (10F - 40F)/(6,000ft. - 2,000ft.) Result = -30F/4,000ft. Answer: -7.5F / 1,000ft. Using the ELR to Estimate an "In-Between" Temperature The previous ELR means that the air temperature is cooling 7.5 F for each 1,000 feet of elevation. Therefore, one can use this ELR value to estimate any temperature between 2,000 and 6,000 feet.
