Let us begin with the fundamentals, namely understanding the significance of these measuring units. The units of length are the kilometer and the mile.

**Examples:**

**1)km to miles**

**Input:**

distance =6.5 km

**Output:**

The given distance 6.5 km in miles= 4.038905 miles

- Java Program to Convert Kilometer to Mile and Mile to Kilometer
- C Program to Convert Kilometer to Miles
- Java Program to Convert Centimeter to Kilometer and Kilometer to Centimeter

**2)miles to km **

**Input:**

distance =6.5 miles

**Output:**

The given distance 6.5 miles in km= 10.460756071261889 km

### 1)Converting kilometers to miles

**Formula :**

1 kilometer = 0.62137 miles.

As a result, the value 0.62137 can be regarded as the conversion factor or ratio for the conversion to occur.

**Algorithm:**

- Define a variable to store the value of the kilo-meter or allow user input.
- Define and save the value of the conversion factor/ratio in a variable.
- Create a variable to hold the value of a kilometre converted to a mile. Write the logic for converting kilometres to miles using conversion factor
- Using the print() function, show the converted value.

**Below is the implementation:**

# given the distance in km distkm = 6.5 # conversion ratio conversion_ratio = 0.62137 # converting the km to miles distmiles = distkm*conversion_ratio # print the distance in miles print("The given distance", distkm, "km", "in miles=", distmiles,"miles")

**Output:**

The given distance 6.5 km in miles= 4.038905 miles

### 2)Converting miles to kilometers

**Formula :**

1 mile= km / 0.62137

As a result, the value 0.62137 can be regarded as the conversion factor or ratio for the conversion to occur.

**Algorithm:**

- Define a variable to store the value of the miles or allow user input.
- Define and save the value of the conversion factor/ratio in a variable.
- Create a variable to hold the value of a miles converted to a kilometer. Write the logic for converting miles to kilometer using conversion factor
- Using the print() function, show the converted value.

**Below is the implementation:**

# given the distance in miles distmiles = 6.5 # conversion ratio conversion_ratio = 0.62137 # converting the miles to km distkm = distmiles/conversion_ratio # print the distance in km print("The given distance", distmiles, "miles", "in km=", distkm, "km")

**Output:**

The given distance 6.5 miles in km= 10.460756071261889 km
