Conversions
It is a sad truth that much of what we learn is based on expanding and relating to things we already know. Because of that we are forced to supply some "rule of thumb" style conversions for other systems.
In addition, we supply some common constants expressed in UMS units.
Approximate Conversion Factors
1 t = 2.817938 x 10-15 meters.
1 d = 9.109390 x 10-31 kilograms.
1 f = 9.399629 x 10-24 seconds.
1 s = 1.301025 kelvins.
1 z = 1.602177 x 10-19 coulombs.
1 jp = 903.750555 moles.
1 T = 2.817938 meters = 9.245203 feet.
1 hbk = 910.953447 grams.
1 J = 939.96297 seconds = 15.66605 minutes.
1 bm = 108.79201 days.
1 hf = 29786.24 Gregorian years.
1 S = 22.376610 liters = 5.911275 gallons.With the introduction of new units, the values of various physical constants, familiar to any science or engineering student, are changed. (The friedman, denoted fr, appears in some of these constants. It is the universal energy unit; 1 fr = 1 d×t2/f2. Also present is the nudge, the universal unit of force. 1 n = 1 d×t/f2)
