A Visual Guide to Converting Miles to Kilometers (with 9 Easy Steps)

1. 1

   Record the distance in miles. How to convert between miles and kilometers is covered here. To begin, enter the mileage you wish to convert. Put it into your calculator if you have one.

   • To better understand, let's use an illustration. To begin the process of converting 50 miles to kilometers, we can write the distance as follows: 50 miles

2. 2

   Increasing by one 6 The number of miles in kilometers is your answer. That settles the matter [1]

   • The solution to our example can be found as follows: 50 1 With 6, you get 80 km.
   • Please label everything with "kilometers." Simply replace "m" with "km" to indicate kilometers. Leaving it off could cost you points if you're doing this for school.
   • See the article "How to Multiply Decimals" on WikiHow if you're having trouble with this operation.

   Simply multiply by 1 for an exact conversion. 60934 One mile is slightly more than a distance of 6k It's closer to 1 609347218694 In this document, the United S Confining the Meaning of a Survey If you need a more precise answer, feel free to use as much of this number as you like. [2]

   • Simply multiplying 50 by 1 gives us the exact distance in kilometers. 609347 Using this method, we obtain 501 609347 = 80 That's 46735 km, or about 500 meters further than the previous estimate.
   • This is only necessary for extremely accurate conversions. Just use 1 For most purposes, a number 6 will do.

4. 4

   Simply divide by 1 to convert back to miles. 6 It's simple to convert back to miles. If you want to divide by 1, you can think of it as the inverse of multiplying. You need to "subtract" 6 to perform a multiplication "backwards" [3]

   • 80/1 was our first example. Six times 50 miles is the starting point.
   • If the denominator was not 1, then Instead of dividing by 6, divide by 6 The division by 1 in the alternative example given above 609347

1. 1

   Express the distance as a fraction greater than one Using a fractional approach to your measurements ensures that you always end up with the correct answer (and units). In order to begin, write your total distance traveled as the numerator of a fraction. Put a 1 in the denominator (the bottom of the fraction). [4]

   • For example, let's determine how many kilometers there are in 5 4 miles A fraction would look like this: 5 4 miles/1
   • The units must always be included in the fractions when performing this type of conversion. They'll be useful down the line. [5]

2. 2

   Type a fraction using the ratio of kilometers to miles. How many kilometers are in a mile? Let's make a fraction to find out. Actually, it's much simpler than it sounds; for clarification, see below.

   • Around one million of them are known to exist. There are six kilometers in a mile. This will be useful as a foundation for our fraction. To express this fraction graphically, we would put "1.6 kilometers" in the top (or numerator) and "1 mile" in the bottom (or denominator) parts. The result is 1 A distance of 6 km/1 mi

3. 3

   Any units that appear in both the top and bottom lists should be multiplied and subtracted. Multiplying the two fractions together is all that's left to do. Help with multiplying fractions is available in our article on the subject. Multiplying by a factor that has the same denominator and numerator can be simplified by looking for units that appear in both. If you come across a pair, mark them both as eliminated. [6]

   • Here, we use a sample of 5 4 miles/1 × 1 Distance of 6 km / 1 mi For this reason, we can eliminate both instances of "mile" because they appear in the wrong places (on top and bottom, respectively) in the first and second fractions, respectively. When we do the multiplication, we get the number 8. 64

4. 4

   Answer using the remaining measurement units. All but one unit should have been eliminated in the previous step. Your solution can be broken down into these parts.

   • The answer is 8 because kilometers is the only unit that hasn't been crossed out. Distance of 64 km

5. 5

   Carry on in this fashion to construct more involved transformations Having mastered quick conversions, you can apply the same strategy to more involved conversions. Repeat the previous procedures. To get the answer in the units you want, write your starting measurement as a fraction over 1, then write your conversions as fractions so that the units cancel. [7]

   • In this case, let's say you're interested in the value of 5 Converting 4 miles to centimeters A mile is 3,280 centimeters, and you have no idea how many centimeters 1 mile is. There are 6 km in 1 mi, 1 000 m in 1 km, and 1 m in 100 cm. Here's all the background you need to pose the question: 5 4 miles/1 × 1 6 km = 1 mi | 1000 m = 1 km | 100 cm = 1 m
   • In this case, you'll see that every measurement system, with the exception of centimeters (which only appears once), cancels out. After doing the math, you get an answer of 864,000 cm.
