Pharmacists must know a lot of chemistry and biology so they can understand the effects that drugs (which are chemicals, after all) have on the body. Most pharmacy programs require four years of education in a specialty pharmacy school. Lets start with a very simple conversion.
Although that may sound straightforward, pharmacists in the United States must hold a doctorate in pharmacy and be licensed by the state in which they work. Unit conversion is a multi-step process that involves multiplication or division by a numerical factor, selection of the correct number of significant digits, and rounding. Extensions which apply only to Units Calculator are shown with a light grey background. As long as the math is performed correctly, you should get the same answer no matter which method you use.Ī pharmacist dispenses drugs that have been prescribed by a doctor. convert between common units used in chemistry and science by entering the number to convert, selecting its units using one of the drop down menus on the right hand side and then select the units you wish to convert to. If you do all the steps together, the restriction for the proper number of significant figures should be done after the last step. Convert among units for any base unit of measure such as gram or meter or second or byte, etc. enter a chemical, physical or mathematical constant into a calculation by using the drop down menu on the right hand side. We can write 1 as 100 cm1 m and multiply:ģ.55\textĮither method-one step at a time or all the steps together-is acceptable. To convert from g into units in the left column divide by the value in the right column or, multiply by the reciprocal, 1/x. Then we multiply this quantity by a conversion factor, which is the same as multiplying it by 1. To solve the problem more formally with a conversion factor, we first write the quantity we are given, 3.55 m. If there are 100 cm in every meter, then 3.55 m equals 355 cm. medical software, clinical software, medical systems, medical calculators, clinical calculators, medical information processing, practice guidelines. How many centimeters are there in 3.55 m? Perhaps you can determine the answer in your head. A fraction that has equivalent quantities in the numerator and the denominator but expressed in different units is called a conversion factor.
Next, select the starting unit and enter a value in the FROM input. To make chemistry unit conversions, first choose the chemical in the top pull-down selector. SI units: Système Internationale dUnités US units: Gravimetric, imperial, or traditional English units. We know that 100 cm is 1 m, so we have the same quantity on the top and the bottom of our fraction, although it is expressed in different units. In this calculator, mcg is the abbreviation for micrograms.
