ACTIVITY GUIDE 2 : METRIC SYSTEM Previously metric and apothecary systems of weights and measures were used in the health field. Currently the metric system is favored and used in this learning packet. THE METRIC SYSTEM (Liters and Grams). Basic metric units used in nursing: Liter for volume (fluids) Gram for weight (solids) Commonly used equivalents within the metric system: Volume or fluid: 1 cubic centimeter (cc) = 1 mL (approximate equivalent) 1000 milliliters (mL) = 1 liter (L) 500 milliliters (mL) = 1 pint (pt) 30 milliliters (mL) = 1 fluid (fl). ounce Weight or mass: 1000 grams = 1 kilogram 1000 milligrams = 1 gram 1000 micrograms = 1 milligram Rules for writing metric dosages or amounts: 1. Metric measurements are written in Arabic decimal numerals. Example: 250, 0.5, 1.0, 0.25 2. The unit of measure follows the dosage. Example: 1.0 Gm. 500 mg. 3. To change milligrams to grams move the decimal point three places to the left (divide by 1000). Example: 500 mg. (500.0) = 0.5 Gm. 4. To change grams to milligrams move the decimal point three places to the right (multiply by 1000).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
