What conversion factor is used for converting kilograms to grams?

To convert kilograms to grams, the conversion factor used is 1000 because one kilogram is equivalent to 1000 grams. This means when you have a measurement in kilograms, you multiply it by 1000 to get the equivalent weight in grams. For instance, if you have 2 kilograms, you would calculate it as 2 x 1000, resulting in 2000 grams.

Understanding this relationship is pivotal in medication math because many medications are dosed in milligrams or grams, so being able to accurately convert between these units is crucial for ensuring proper dosing and patient safety. The other options do not represent the correct relationship between kilograms and grams, as they suggest incorrect factors for conversion.
