How to measure quantities

1 drop from eyedropper = .02 ml
1 teaspoon = 6ml
1 tablespoon = 20ml
1 ml = 1cc
1 teacup = 180ml
1 gm = 15 gr grains = 1000 mg
1 level teaspoon = 6gm +/-
1 level tablespoon = 20 gm +/-
1 teacup = 220 gm +/-
1 ppm = 1mg/litre -or- 1 mg/1000ml

Percent solutions are 1000mg/100cc. For example a 2% = 20mg/cc, 5% = 50mg/cc, 5.5% = 55mg/cc, etc...

Prepare a 1% solution of Malachite green (500 mg of powder in bottle). How many mL of sterile water will you use?
Answer: First convert 1% solution to mg/cc. A 1% solution is the same as 1000 milligrams in 100 cc or 10mg/cc.
