Grains to Grams: Divide the number of grains by 15, then divide that number by the number of grams on hand.
EX: Aspirin grain 10 PO is ordered. Strength on hand is 0.3 gram Tablet. 10/15= .6666 then .6666/0.3= 2.222 .........Answer is 2 Tablets.
Grains to Milligrams: Divide the number of grains by 15, then mutiply by the number of mg on hand.
EX: Physician ordered Coumadin gr 6 po. On hand Coumadin 5 mg/tablet. So 6/15=0.4 take 0.04 mutiply by 5mg=2.....................Answersis 2 Tablets.
One thing that is helpful with Grains is to make a Conversion Clock. 60mg(60mins) = 1grain(1hour), EX: 1/4 grain=15 mg; 1/2 grain= 30 mg; 3/4 grain= 45 mg. If you draw the clock, it helps for visual learners.
A:For Example #1, the answer is correct. I used ratio & proportion when solving these problems. It is much easier and can keep track of the units.
For Example #2, the answer is wrong. Here how I solved the problem:
1. Know that 1 grain = 60mg - 65mg (I usually use 60mg).
2. Ratio & Proportion: 1gr/60mg = 6gr/x. Now cross multiply. Solve for x
3. You'll end up with x = 360mg (390mg if you use 1gr/65mg).
4. Ratio & Proportion: 360mg/x = 5mg/tab. Now cross multiply. Solve for x
5. x = 72 tabs ( x = 78 tabs if you use 1gr=65mg).
A mil is 1/1000 of a 'something.' It can be a gram, liter, meter, or other SI unit. A milligram is 1/1000 of a gram, so in essence they are the same measurement.
1 gram = 1ooo milligrams Mills is in slang.
1000 milligrams is equal to 1 gram, therefore 2.8 grams is equal to 2800 milligrams. To convert from grams to milligrams multiply by 1000, and to convert milligrams to grams divide by 1000.
Converting grams to milligrams can be easy. The amount in grams, is multiplied by 1000, to convert it to milligrams. 1.5 grams is 1500 milligrams.
You cannot convert milligrams to centimeters. Milligrams is a measure of mass. Centimeters is a measure of length.
1 gram = 1ooo milligrams Mills is in slang.
One kilogram is one million milligrams, and one milligram is one millionth of a kilogram. To convert kilograms to milligrams, multiply by one million. To convert milligrams to kilograms, divide by one million.
To convert lbs to milligrams multiply by 454,000
There are 1,000 milligrams in a gram.
Multiply the number of milligrams by 1000.
There are 100 milligrams in one decigram. Therefore, to convert decigrams to milligrams, multiply by 100. For example, 3.2 decigrams is equal to 3.2 x 100 = 320 milligrams.
There are 1000 milligrams in a gram. Therefore, 122 grams will be 122,000 milligrams.
One gram equals 1,000 milligrams.
