Study Notes
Weight and Volume Units
- 1000.000 grams is equivalent to 1 kilogram in the metric system.
- The primary unit of volume in the International System of Units (SI) is the cubic meter (m³).
- 1 deciliter (dl) is equal to 0.1 liters (L).
- 0.000,001 liter corresponds to 1 microliter (µL) in the metric system.
Pharmaceutical Standards and Measurements
- The transition to the International System of Units is driven by the need for standardization and precision in scientific measurements.
- The pharmaceutical research and manufacturing industry predominantly uses the metric system.
- 1000 milligrams (mg) is equivalent to 1 gram (g).
- There are 1000 nanograms (ng) in 1 microgram (µg or mcg).
- 1 gallon is equivalent to 128 fluid ounces (fl. oz.).
Measuring Instruments and Concentration
- A graduated cylinder or micropipette is commonly used for measuring small volumes in pharmacy practice.
- The concentration of a solid ingredient in a liquid vehicle is typically expressed as weight/volume (w/v).
- 1 pound (lb, Avoirdupois) is equivalent to 453.592 grams.
