Divide the airfield altitude in feet by 30 to get the number of millibars above MSL. Add this to the QFE to get QNH or subtract it from QNH to get QFE. For example, the airfield elevation is 200 feet. Dividing by 30 gives us 6.66r.

Brisbane's current QNH is 1023. In the International Standard Atmosphere(ISA) there is a 1 hPa difference for each 30 feet vertical change in height in the lower levels. 10 hPa * 30 = 300ft height variation. Because our QNH is above 1013 we have more air pushing down on us causing a higher local pressure.

We wish to determine the value of Q - the quantity of heat. To do so, we would use the equation Q = m•C•ΔT. The m and the C are known; the ΔT can be determined from the initial and final temperature. With three of the four quantities of the relevant equation known, we can substitute and solve for Q.
