What type of measurements requires the use of kilograms and milligrams.

Measuring weight is one of the most common things that we do in our everyday life with any other measuring unit so much. Probably, when we go shopping, the items which we buy on the basis of mass are priced via mass. As they are quantity based with no exact measured calibration which can be kept together (like sugar which we cant keep altogether as 500 grams without actually measuring it). We do come across several units of mass like Kilogram, gram, milligram which are both used for mass and weights along with others. We know how gram and kilogram are related. But do you know how many milligrams are in a kilogram?

**How many Milligrams in a Kilogram**

Why mass and weight are not exactly the same?

Do note that mass and weights are not exactly the same thing while both have the same exact units conventionally. Mass is actually the quantity of matter present with exact density over the whole body. Weight is how fast the mass is pulled down to the surface of the earth(let us not go onto other planets). As Weight=Mass*gravitational acceleration and this equation can be used to find out the actual mass of an object in terms of the mass units we use. Also, note that the weight of an object will always vary due to the gravitational acceleration pull which also varies on the different poles of the earth. Mass will never vary as the amount of matter (which is the no of atoms packed together in the body) will never vary or it might but that is highly negligible and can be neglected as it won’t come down to the actual calculated number.

**Finding out the actual mass of the content.**

If you were to find out the actual mass of an object, you will ultimately get a value which will be equal everywhere in our solar system, while due to variation of the G-pull, the weight will vary (as 30KG will become 5KG on moon, 0KG in space, but the EKG which is the mass will be same everywhere since the amount of matter in a body will not get diminished if kept in such a condition. The aim of mentioning these things is to make you understand how the two measures are different in nature yet sounds similar ).

The formulaic difference between mass and weight.

When we consider using mass and weights, there is a slight confusion that sounds like this. Mass is actually weighted alone. Whereas weight is the product of mass and Gravitational pull value.

Lets us first analyze the old way for the conversion.

**What units were used at first for measuring mass and weights?**

At first, there were no calibrated mass units like which we use today. There were some units like an ounce, pounds which were used at first. These were used as units with a specific calibrated item of the unified mass which gave equal balance readings in a beam balance or a spring balance(these are two things which are used for the measurement of mass and weights). Then this was used for measuring and calibrating (temporarily) items for finding out their price per mass value. As mentioned, items which have no specific size or are too small for the mass units to configure, these are considered to be used on bulk for their practical calibration.

**How many milligrams in a kilogram?**

In order to find out a conversion of a unit in the same dimension, we only need another unit to get a value which is actually calibrated and is verified. Then the calculation is just a matter of words and number of 10s we put. Next, we clear out the relation between milligrams, grams, and kilograms. Simple convention proves that one kilogram is equal to 1000 gram. And one milligram is equal to 1/1000th of a gram. Or on the reverse, one gram is equal to 1000 milligrams. Which makes it clear that one kilogram is equal to 1000grams X value of one gram in milligram(ie = 1000) and the result is 1000,000 milligrams. So, how many milligrams in a kilogram? It is equal to 1 million milligrams.

We use the term “equal to” instead of equivalent since the units here we used are actually the exact bigger and smaller forms of one another in the same dimension. If we look carefully, there is a single stop unit ie; gram. The others are a just higher unit (ie; kilogram) and lower unit (ie; milligram) which have specific prefixes which define the meaning of the unit and the actual relation with the stop unit.

**Is it true for all for other units when taken in equivalent forms?**

The above conversion also holds true for any other conversion unit in terms of grams( for ounce and pound too), which also makes the other mass units true for their value. For example, if we take an ounce, one ounce is equal to 28.3495 gram or 0.0283495 kilograms or 28349.5 milligrams. If we divide the kilogram equivalent by the milligram one, we will get a value which is equal to 1 million. Thus it holds true for ounce too.

Now we know how to deal with a mass and weight conversion in the right way. We also know about the other mass units and finally the answer to the question of how many milligrams in a kilogram which is 1 million or 1,000,000 milligrams.
