The<br \/>\nbasic equations for temperature, <i>T<\/i>, pressure, <i>p<\/i>,<br \/>\nand density ?, are given in Sections 3 to 5 while the defining<br \/>\nconstants and temperature gradients are given in Tables 11.1 and<br \/>\n11.2. Table 11.3 gives numerical expressions for <i>T<\/i>,<br \/>\n<i>p<\/i> and ? while Table 11.4 gives the reverse expressions for<br \/>\ndetermining pressure height for a given pressure, and the<br \/>\ndifference between pressure height and geopotential height for<br \/>\nspecified off-standard atmospheres. The relationships between<br \/>\npressure, pressure height and geopotential height are considered in<br \/>\nSection 7 while the relationship between geopotential height and<br \/>\ngeometric height is presented in Section 8.
