Convert 500 mcg to mg?

Often, we need to convert mcg to mg when we are dealing with medicines. Let’s take an example of how to convert 500 mcg to mg.

Conversion of units and values from greater to smaller and vice versa is required for the convenience of the mathematical expression. Sometimes the value is too small and we need to express it in the form of a microgram whereas sometimes we require the value in milligram. Here we are asked to perform the conversion of 500 mcg to mg.

How to convert 500 mcg to mg? The quick answer 500 mcg = 0.5mg

Basic Concepts

Here we first need to learn about the relationship that exists between microgram and milligram.

1) It is to be noted that 1 mg=1000 mcg
2) Now a microgram is a smaller unit of weight and when we convert a smaller unit of weight to higher, we need to divide the value by the given relation.
3) Here we need to divide 500mcg by 1000 to yield the answer in the higher unit microgram.

Calculation of converting 500 mcg to mg


1 mg = 1000 mcg


1 mcg = 0.001 mg

Therefore, required answer,

500 mcg = 500 ÷ 1000 = 0.5 mg


500 mcg = 500×0.001= 0.5 mg (where 0.001= 1/1000 in decimals)

Best conversion unit of 500 mcg

The best conversion unit is required to represent the values more systematically and is essential for mathematical expressions. It is defined as the lowest possible value of the given unit without going below one.

Hence in this case the best conversion unit of the given data is 500mcg. This is because the lowest possible value before one makes the calculations way easier for you to initiate.
