There are many websites on the internet that can convert miles to kilometers.If you never have an internet connection, learning how to do it yourself is a good idea.It's important to remember that there are 1.6 kilometers in a mile.You can get kilometers by taking your number of miles and dividing it by 1.6.
Step 1: The number of miles is written.
You will learn how to get kilometers from miles.Write down the number of miles you want to convert.To use a calculator, type it in.Follow along with an example.We would start converting 50 miles into kilometers by writing it out.
Step 2: ply by 1.
The answer will be the number of kilometers.There is only one thing to it.50 1.6 is the answer we can find in our example.Don't forget the "kilometers" label.It is possible to write "km" for a short time.If you leave it off, you may lose points.If you need help with multiplication, check out How to Multiply Decimals.
Step 3: For precise conversions, multiply by 1.
It's not exactly 1.6 kilometers.It's about 1.609347218694.This is the official definition of the U.S. Survey.To get your answer more precise, use as much of this number as you can.If we want to know how far away 50 miles is, we can just divide 50 by 1.609347.50 1.609 347 is about half a kilometer more.For really precise conversions, you only need to do this.Just use 1.6 for basic purposes.
Step 4: Divide by 1 to get back to the original distance.
It's easy to get back to miles.If you divide by 1.6, you can "undo" the multiplication.Right back where we started.Divide by 1.6 if you used a different decimal.We would divide by 1.609347.
Step 5: The number of miles should be written in a fraction.
You can convert in a way that makes it easy to get the right answer every time, if you treat your measurements like fractions.Write your number of miles as the top part of the fraction.Write a 1 in the bottom part of the fraction.We want to figure out how many kilometers there are.We would write a fraction like this.The units should be included in the fractions when you're converting this way.Later, they will be important.
Step 6: The ratio of kilometers to miles is used to write fractions.
You want to show how many kilometers are in a mile.This is a lot easier than it sounds.There are 1.6 kilometers in a mile.This can be used to build our fraction.In the top part of the numerator, we would write "1.6 kilometers" and in the bottom part, "1 mile."This gives us something.
Step 7: Cancel units on top and bottom.
Just add up the two fractions.If you need help with fractions, read our article.Look for units that show up in both the numerator and the denominator.Cross both out when you find a pair.We have a mile and a half in our example.We can cross both "miles" out if "mile" appears on top and bottom in the first and second fractions.We get multiplying.
Step 8: You can use the left units for your answer.
All of the units should have been crossed out in the last step.The units are in your answer.We know our answer is, because "kilometers" are the only units not crossed out.
Step 9: Continue the pattern to build more complicated conversions.
You can use the same approach for longer conversions now that you know how to do them.Follow the same steps.If you want your answer in, write your measurement as a fraction over 1 and then convert it to fractions.Let's say you want to know what the distance is.You don't know the conversion for miles to centimeters, but you do know that there are 1.6 kilometers in a mile, a kilometer and a meter.All of the units cancel except for centimeters, because it only appears once.Your final answer is.
