mm Hg = inch Hg ∗ 25.4 K = (5/9) ∗ (°F -32) - 273.15
mm Hg = 760 ∗ (54,041 - feet ASL) / (54,041 + feet ASL) K = °C + 273.15
mm Hg = 760 ∗ (16,472 - meters ASL) / (16,472 + meters ASL)
mm Hg = mB ∗ 0.75006
mm Hg = hPa ∗ 0.75006
3.5 Basic Operating Equations
This section lists the basic operating equations used within the 35360A TRACKER Display to produce its
dose and dose rate measurement values for display on the VFD. These equations are expressed in
terms of a set of basic operating quantities which are described in Table 3-3.
3.5.1 Charge
Although charge is not a value which can be displayed directly by the 35360A TRACKER Display, it is an
intermediate result upon which the dose value directly depends.
