The trace mineral content of most feeds and supplements is provided in terms of parts per million (ppm). A ppm is the same as mg/kg (1 mg is a millionth of a kg).
To do calculations, you need to convert lb or oz to kg using the following conversions:
· 1 lb equals 0.454 kg
· 1 oz equals 0.0284 kg
Example #1: Your hay contains 140 ppm of iron. How much iron is in 20 lbs of hay?
Step 1: 20 lb X 0.454 kg/lb = 9.08 kg
Step 2: 9.08 kg X 140 mg/kg = 1271 mg of iron
Example #2: Your supplement contains 12 ppm of selenium in each ounce and you are feeding 2 ounces per day. How much selenium are you feeding?
Step 1: 2 X .0284 kg/oz = 0.057 kg
Step 2: 0.057 kg X 12 mg/kg = 0.68 mg of selenium
Formulas to remember:
· Convert lb or oz to kg: lb X 0.454 = kg; oz X 0.0284 = kg
· Calculate to find mg: kg X ppm (or mg/kg) = mg
