1 Kilogram (kg) = 1000 Grams (g)
When you are weighting different items, it is normal that you need to make conversions between different units. And one of the easiest conversion ratios that there are is when you are trying to convert units within the same measurement. In today’s case, we are referring to the metric system and the conversion from kilograms to grams.
So, while we already showed you how many grams are in a kilogram, we will also explain to you how you can easily make this conversion as well as the reverse one (from grams to kilograms).
However, before we actually start with this practical examples and formulas, we believe that it is a good idea to know a bit more about the metric system as well as to know a bit more about each one of these specific units of measurement – the kilogram and the gram.

Understanding The Metric System
Even though the International System of Units (or SI as it is also referred to) and the metric system tend to be used interchangeably, the truth is that they are different. In fact, the SI is more accurate technically.
One of the things that you need to understand about the SI is that it covers all the basic measurement needs. And for that, it is based on 7 base units.
The reality is that you may need to relate different measurements mathematically. And this won’t only be happening at school. Let’s say, for example, that you just measured the length of a soccer field and you discovered that it is 120 meters (394 feet) long. Then, you measured the width and you discovered that it is 90 meters (295 feet). But, if you want to determine the area of this soccer field, you will not only need to multiply the length by the width (in numbers) but also the units as well. Therefore, you would need to do the following:
area of the soccer field = length × width
area of the soccer field = 120 m × 90 m
area of the soccer field = 10,800 m^2
Both area and volume are derived units since they are defined in terms of an SI base unit. Besides, there are some units that while are not part of the metric system officially, they tend to appear frequently. So, the Si accepts these units for use with its family of measures. Some of these units include the day, hour, and minute, just like the metric ton and the astronomical unit. Besides, all of these units can be defined according to the SI base units.
One of the problems of the base unit that is used is that it can be incredibly large or incredibly small to describe an object properly. For example, let’s imagine that you wanted to measure the length of an ant. If you were using the Si base unit – the meter, you would need to state that the ant has a length of 0.003 meters. While this would be difficult to even imagine its length in your mind, it would be just impossible if you wanted to express the width of an atom or of a human hair in meters.
So, when you are measuring a very small object, you will use the millimeter instead of the meter. In case you don’t know, one meter is equal to 1000 millimeters.
As you can see, in order to convert meters to millimeters, you just need to multiply by 1000. So, in the case of the length of the ant:
0.003 meters X 1000 = 3 millimeters (mm)
On the other hand, when you need to measure a large distance such as from one city to a different one, you can use the kilometer instead of the meter.
So, let’s say that you know that the distance between two cities is 640,000 meters. Since:
1 kilometer (km) = 1000 meters (m)
Then, you will need to divide the distance in meters by 1000:
640,000 m = 640,000/1000
640,000 m = 640 km
Ans this is exactly the same thing that you can find with grams and kilograms as you are about to see below.

What Is A Kilogram?
Just like the kilometer, the kilogram is defined as a base unit of the SI. The kilogram is the unit that is used to measure mass and it is defined as being equal to the mass of the International Prototype Kilogram (IPK), which is almost exactly equal to the mass of one liter of water.
So, when you need to measure weight, you can use kilograms, especially when you are weighting heavier or larger items. It is often used to weight people, food and even other items such as books.
The kilogram is also referred to as the kg.

What Is A Gram?
A gram is also a unit of mass and is used with the metric system. The gram is equal to one-thousandth of a kilogram.
When you need to weight smaller items, the gram is preferably used instead of the kilogram. This tends to occur when you are weighting groceries or even everyday objects.
One of the things that you may not know is that food products have strict regulations and need to follow certain standards. One of them is that their labels need to include measurements in grams.
A gram is the approximate weight of a cubic centimeter of water and it is also referred to as g.

How Many Grams In A Kilo – Manual Calculation
As we have already shown you so far, it is incredibly easy to determine how many grams in a kilo. After all, you just need to use our converter. However, in case you don’t have access to the Internet at the moment that you need to make the conversion, then it is always a good idea to keep in mind the ratio conversion between grams and kilograms.
As we already mentioned above,
1 kg = 1000 g
So, let’s say that you are following a recipe and that you need to convert kilograms into grams. According to the recipe that you are folowing, you need to add 1.1 kg of pork.
So, how many grams are in 1.1 kilograms?
Looking at the conversion ratio:
1 kg = 1000 g
You will need to:
1.1 kg = 1.1 X 1000 g
1.1 kg = 1100 g
So, what about if you need to add 0.7 kg of potatoes?
Well, again, you will need to turn to the conversion ratio of the two units of measurement:
1 kg = 1000 g
And then:
0.7 kg = 0.7 X 1000 g
0.7 kg = 700 grams
And here’s a last practical example. Let’s say that you are in the middle of an exam and you need to answer the following question: How many grams are in an eighth of a kilogram?
Again, you need to turn to the main conversion ratio between these two units of measurement:
1 kg = 1000 g
So, since you want to know how many grams are in an eighth of a kilogram, you will need to:
1/8 kg = 1/8 X 1000 g
1/8 kg = 0.125 X 1000 g
1/8 kg = 125 g
So, you can then answer that there are 125 grams in an eighth of a kilogram.
As you can see, all you need to do to convert kilograms into grams is to multiply the number of kilograms by 1000.

How to Convert Grams to Kilograms
While you won’t be able to use our converter to convert grams to kilograms, we decided to show you how you can easily make this conversion by hand.
The truth is that all you need to keep in mind to convert grams to kilograms is that the conversion ratio is exactly the same:
1000 grams = 1 kilogram.
Let’s take a look at two different methods that you can use to convert grams into kilograms.
Discover more about the orders of magnitude (mass).
Method #1: Converting With Math
In this method, we are going to show you how you can easily convert grams into kilograms by using the conversion ration between these two units of measurement.
Let’s say that you are looking to know how many kilograms there are in 20,000 grams.
So, remembering the conversion ratio between the two units of measurement:
1000 grams = 1 kilogram
In order to convert grams into kilograms, you will need to divide the number of grams by 1,000. So:
20,000 grams = 20,000/1,000 kg
20,000 grams = 20 kg
So, you can then state that there are 20 kilograms in 20,000 grams.

Method #2: Converting By Shifting The Decimal Point
As we already mentioned at the top of this page, converting kilograms into grams or grams into kilograms are two of the easiest conversions you can make between units of measurement. Besides, the conversion ratio is easy to memorize.
However, in case you don’t even want to bother in memorizing that 1 kilogram is equal to 1000 grams, you can simply make the conversion by shifting the decimal point.
The only reason why you can do this when you are converting grams to kilograms is that metric units are always a multiple of 10 apart from each other.
As a side note, besides this is true for grams and kilograms, it is also true for meters and kilometers. In fact:
1 Kilometer (km) = 1000 Meters (m)
1 Centimeter (cm) = 10 Millimeters (mm)
So, getting back to our conversion from grams to kilograms, let’s use an example so that it can be easier for you to understand this method.
Let’s say that you want to convert 49 grams into kilograms. In order to do this conversion by shifting the decimal point, you need to know that when you are converting kilograms to grams, you will need to shift the decimal point three spaces to the left.
So, if you were to move the decimal point just one space to the left, you would have 4.9 grams. If you were to move te decimal point two spaces to the left, you would have 0.49. But since you need to move the decimal point three spaces to the left, you will get: 0.049.
So, you can then conclude that:
59 grams = 0.049 kilograms
Conclusion
As you can see, it is pretty simple and straightforward to know how may grams there are in a kilogram. Besides, we have provided you with all the tools you need to ensure that you always make this conversion the right way and that you get to the right result.
