Some helpful conventions and constants (not inclusive list, consider these as examples only):

Physiological saline = 0.9% NaCl = 0.9 gram NaCl/100 ml water

Total blood weight = 7.0 % of body weight (BW) (an overall average)

Normal PCV = 45 % (an overall average)

One gallon = 3.8 liters = 8.3 lbs. = 4 quarts (qts.) = 8 pints (pts.) = 16 cups = 128 fluid oz.

One meter = 39.37 inches = 10dm = 100 cm = 1000 mm
