This conversion is very straight forward to calculate as it is a simple case of moving the decimal point to the left. In this case since it is converting a milligram to a gram you would move the decimal point 3 places left; So, 100 mg equals how many grams? 100 milligrams = 0.1 grams. Many exams questions will include conversion such as 100 mg convert to grams. Here is some more information to help understand the relationship between grams and milligrams.
'Milli' is Latin, meaning thousand; similarly tri means three, quad means four and oct represents eight. There are many instances of the use of 'milli' in modern English; for instance, Millennium (a thousand years), millipede (a thousand of legs) etc. In maths, this theory explains logic in many areas and allows for much quicker calculation (as is the case with the original question here). Here are some other mathematical examples and their meanings;
- Millisecond - this is a thousandth of a second; so there are 1000 milliseconds in one second
- Millimetre - again there are a thousand millimetres in one metre; so 1000 millimetres equals one meter
- Millilitre - one thousandth of a litre
- And finally, million - This is slightly different to the theory in the examples above which would suggest the word million refers to the number 1000. It raises the question, why do we call millions, millions? The answer is, in fact, that a million is so called as it is actually one thousand thousands.
Converting of 'mill-' measurements therefore, is fairly straight forward, and is simply a case of dividing by one thousand. Similarly, 'cent-' measurements are equally as easy to convert as they use the same rule but by 100 instead of 1000.
