| Question | Answer |
|---|---|
| g > mg 1 g = 1000 mg To multiply by | |
| mg < g 1000 mg = 1 g To divide | |
| mg > mcg 1 mg = 1000 mcg To multiply by | |
| Mg are smaller than g; Mcg are smaller than mg To covert from g to mg, MULTIPLY the g by 1000 To convert from mg to mcg, MULTIPLY the mg by 1000 | |
| To convert from mg to g, DIVIDE the mg by 1000 To convert from mcg to mg, DIVIDE the mcg by 1000 | |
| 1 g = 1000 mg 1 mg = 1000 mcg | |
| gr 1 = 60 mg | |
| 1 kg = 2.2 lbs | |
| 1 tbs = 15 mL 1 tsp = 5 mL 1 oz = 30 mL | |
| Liter = L | |
| Milliliter = mL | |
| 1000ml = 1 L | |
| 1 teaspoon = 5 mL | |
| 1 tablespoon = 15 mL | |
| 1 ounce = 30 mL | |
| 1 pint = 480 ml (500ml is 0.5 L) | |
| 1 quart = 960 mL | |
| 60 mg = gr 160 min = 1 hr | |
| 15 mg = gr ¼15 min = ¼ hr | |
| 30 mg = gr ½30 min = ½ hr | |
| 45 mg = ¾ gr45 min = ¾ hr | |
| Dosing: Carry division to two places (hundredths place) and round to nearest tenth. Exception–1 ml tuberculin syringe is carried to thousandths and rounded to nearest hundredth | |
| Cannot round some medications: Heparin | |
| Cannot round some increments: Units | |
| 2.2 lbs = 1 kg |
