Veterinary Weights Measure And Conversions

How Can You Possibly Keep All These Numbers Straight?

I don’t always remember them either. So, I have them on a chart nailed to the wall:

  • sid : once a day
  • bid : twice a day
  • tid: three times a day
  • qid : four times a day
  • q  : every (as in q 48 hours {hrs} = every two days)
  • sig : “sig” 8hrs (the dose is every 8 hours)
  • prn:  as required
  • # : the number of tablets or capsules in the bottle  #30= Thirty tablets
  • one pound (lb0: 454 grams (gm)
  • one pound (lb) : 0.454 kilograms  (Kg)
  • one ounce (oz) : 28.35 grams (gm)
  • one fluid ounce (fld oz) : 28.35 grams (gm)
  • one grain (gr) : 0.0648 grams  (gm)
  • one dram (drm) : 60 grains (gr) = 3.88 grams (gm)
  • one gallon (gal) :.3.785 liters (L) = 3785 milliliters (ml)
  • one quart (qt) : 0.946 liters (L) = 946 milliliters (ml)
  • one pint  (pt) : 0.473 liters (L)= 473 milliliters (ml)
  • one milliliter (ml) : one cubic centimeter (cc) = one gram of water
  • one liter (L) : 1000 milliliters (ml)
  • one quart (qt) :2 pints (pt)
  • one quart  (qt) : 1.1 liters (L)
  • one inch (“) : 2.54  centimeters (cm)
  • one FDA adult human wt : 65 kilograms (kg)
  • one average FDA child wt : 30 kilograms (kg)
  • one gallon (gal) : 3785 milliliters (ml) = 3.785 liters (L)
  • one ton (ton) : 2,000 pounds (lb) = 908 kilograms (Kg) = 0.907 metric tons
  • one part per million (ppm): 1 milligram (mg)/liter (L)
  • one microgram (mcg) : 0.000001 grams (gm)
  • one microgram (mcg) : 0.001 milligrams (mg)
  • one quart (qt) :.approximately one liter (L) = approximately 1000 milliliters (ml)
  • one pint (pt) : 16 ounces
  • one fluid pint  (fld pt: 16 fluid ounces (fld oz)
  • one pound (lb) of water: approximately 500 milliliters (ml) “A pint’s a pound  the world around”
  • one tablespoon (TBS): approximately 15 milliliters (ml) approximately one-half (0.5) fluid ounces (fld oz)
  • one teaspoon (tsp:..approximately 5 milliliters (ml)
  • one fluid dram (fld dm): approximately 5 milliliters (ml)
  • one milliliter (ml:approximately 15 drops (dps) (some say 20 drops)
  • one milliliter (ml) . 16 minims (the marks on one side of a tuberculin syringe – the other scale is in milliliters
  • one kilogram (Kg) : 2.2 pounds (lb)
  • A 1% solution : 10,000 micrograms (mcg)/ml
  • A 2.5% solution:2.5  grams/100 milliliters (ml)
  • A 10% solution : contains 10 grams (gm)/100 milliliters (ml)
  • one microgram (mcg): 0.001 mg
  • ug/dL or µg/dl or mcg/dl = microgram per deciliter. This is a common way that blood values are reported by laboratories in the United States. A microgram is one millionth of a gram and a deciliter is one-tenth of a liter or 100 milliliters (mls).
