Problem
Use the following chart to do the conversion of 0.013 gram = grain $=$ milligrams. \begin{tabular}{|l|l|} \hline \multicolumn{2}{|c|}{ Approximate Equivalents } \\ \hline 1 teaspoon $=5$ milliliters & 1 kilogram $=2.2$ pounds \\ grain $\mathrm{i}=60$ milligrams & 1 teaspoon $=60$ drops \\ grain $\mathrm{i}=1$ drop & 1 quart $=1$ liter \\ fluid ounce $1=6$ teaspoons & 1 pint $=2$ cups \\ fluid ounce $1=2$ tablespoons & 1 quart = fluid ounces 32 \\ fluid ounce $1=30$ milliliters & 1 gram $=$ grains 15 \\ 1 inch $=2.54$ centimeters & 1 cup $=240$ milliliters \\ \hline \end{tabular} The answer is grain (Type an integer or a simplified fraction.) The answer is milligrams. (Type an integer or decimal rounded to the nearest tenth as needed.)
Solution
Step 1 ：Given that we have 0.013 grams to convert to grains and milligrams.
Step 2 ：From the conversion chart, we know that 1 gram is equal to 15 grains and 1 gram is equal to 1000 milligrams.
Step 3 ：To convert grams to grains, we multiply the number of grams by 15. Therefore, \(0.013 \times 15 = 0.195\) grains.
Step 4 ：To convert grams to milligrams, we multiply the number of grams by 1000. Therefore, \(0.013 \times 1000 = 13.0\) milligrams.
Step 5 ：Final Answer: The conversion of 0.013 grams is approximately \(\boxed{0.195}\) grains and \(\boxed{13.0}\) milligrams.
