The kilogram is a unit of mass, while the newton measures force. The latter is part of the derived units of the International System of Units (SI) and corresponds to kg ∙ m / s2. Nonetheless, the newton can be transformed into a unit of measurement called the kilogram-force; if you know the conversion factor, you can easily switch between them. You can also find online calculators or some high-end scientific calculators that allow you to perform conversions very quickly.
Steps
Method 1 of 3: with Manual Calculations
Step 1. Learn the conversion factor
Textbooks and many conversion tables report that 1 N corresponds to 0.10197 kgf; a useful way to write this concept is the conversion ratio: 0, 10197kgf1N { displaystyle { frac {0, 10197kgf} {1N}}}
. Esprimendolo sotto forma di frazione, dovresti ricordarti che il numeratore e il denominatore hanno il medesimo valore e che il rapporto è pari a 1.
Non dimenticare che qualsiasi frazione in cui il denominatore e il numeratore sono uguali è equivalente a 1. Tale concetto è molto importante perché puoi moltiplicare qualsiasi numero per 1 senza alterarne il valore, ma ti permette di convertire le unità di misura
Step 2. Set up the conversion equation
If you have a quantity expressed in newtons that you need to transform into kilograms of force, you can exploit the conversion factor and establish a simple equation; as long as the conversion ratio is 1, the value does not change.
-
For example, suppose you have a force of 5 N which you want to express in kgf. Set the problem like this:
-
5N = 5N ∗ 0, 10197kgf1N { displaystyle 5N = 5N * { frac {0, 10197kgf} {1N}}}
- .

- When writing the conversion factor, you must remember to set the fraction so that the unit of measurement is">
), ottieni un risultato sbagliato; questa deve essere utilizzata per convertire i chilogrammi forza in newton.
Step 3. Perform the calculations
If you've set up the equation correctly, the final step should be simple multiplication. You should note that the first factor is expressed in newtons and that the same unit of measurement is found in the denominator of the second factor. As in any multiplication between fractions, an element that appears both in the numerator and in the denominator can be eliminated; in this way, only the desired unit of measurement remains (kgf).
-
In the example considered, you can proceed to the calculations like this:
5N = 5N ∗ 0, 10197kgf1N = 0, 50985kgf. { Displaystyle 5N = 5N * { frac {0, 10197kgf} {1N}} = 0, 50985kgf.}
Metodo 2 di 3: con un Calcolatore Online
Convert Newtons to Kilograms Step 04 Step 1. Do a web search
Just type in the words "convert N to kgf"to find different types of calculators. Quickly look at the results offered by the search engine to find the one that has the easiest style and presentation to use. The results obtained do not change, regardless of the tool you choose.
For example, this calculator is very simple to use. There is a text field where you can type the number expressed in newtons; then click on the "Calculate" button and the result will appear in the second text box. If the number you enter is decimal, remember to use a period and not a comma
Convert Newtons to Kilograms Step 05 Step 2. Enter the number in Newtons you want to convert
By using an online calculator you don't have to worry about memorizing the conversion factor; just enter the starting value to automatically obtain the equivalent with the other unit of measurement.
If to carry out the conversion you use the calculator proposed in the previous section of the article, write the number 10 in the box to the right of the letter "N" (newton). Click on the red "Calculate" button and the equivalent expressed in kilograms force will appear in the box to the right of the letters "kg"
Convert Newtons to Kilograms Step 06 Step 3. Some sites allow you to set the accuracy level of the calculations
In this case, you can decide the number of decimal places to consider. If this feature is available, choose the level of accuracy you prefer; the result is expressed with the amount of decimal places you have selected.
For example, if you set a precision level with one decimal place and enter the value of 5 N, the result is 0.5 kgf. If you change the level to two decimal places, you get 0.51 kgf; if you change the precision again and bring it to 5 decimal places, in the solution box you can read 0, 50986.
Method 3 of 3: with a Scientific Calculator
Convert Newtons to Kilograms Step 07 Step 1. Check the calculator's conversion functions
Many "scientific" and "graphic" models are also equipped with a button that allows the conversion of units of measurement. If your calculator also has this feature, you can use it to convert Newtons into kilograms of force; for example, the TI-83, TI-84Plus, and TI-86 from Texas Instruments have this feature.
On the TI-86 calculator you can find "Conv" above key number 5; to activate the function, press the "2nd" key and then 5
Convert Newtons to Kilograms Step 08 Step 2. Activate the conversion tool
First you have to select the units of measurement you want to transform and then perform the calculations. This step varies slightly based on the type of calculator you have, but the basic instructions are basically the same.
If you have a TI-86, press "2nd" and "5"; in this way, you access a menu with the physical quantities that you can convert
Convert Newtons to Kilograms Step 09 Step 3. Choose the size you are interested in
In addition to showing the conversion tool, the calculator display offers a list of options: length, area, volume, time, temperature. Since none of these quantities are the subject of your study, press the "More" button to display five other options: mass, force, pressure, energy and power. Select the F2 key, located at the top of the calculator, to choose the strength.
Convert Newtons to Kilograms Step 10 Step 4. Choose the original unit of measure
As soon as you have chosen to convert the "force", the monitor should present a number of new options that include different units of this magnitude; you have to choose the one you want to convert.
- Enter the number of newtons you want to transform; then choose the F1 key labeled with the letter "N".
- For example, if you are converting 5 N to kgf, press the "5" key followed by "F1". The monitor should display "5N" followed by an arrow and a blinking cursor.
Convert Newtons to Kilograms Step 11 Step 5. Choose the target unit of measure
After entering the original one, choose the one in which you want to transform the number; the list should appear on the screen.
In this case, you want to convert Newtons into kilograms of force. Then choose the key marked with the letters "kgf" and which corresponds to "F4"; the display should suggest: "5N → kgf"
Convert Newtons to Kilograms Step 12 Step 6. Perform the calculation
When the calculator presents the conversion you want to perform, simply press the "Enter" key; the instrument will perform all the mathematical steps and show the result on the display.
