Grade 5 Math: Converting Miles to Kilometers

📏 Understanding Miles and Kilometers

Both miles and kilometers are units used to measure distance. Miles are commonly used in the United States, while kilometers are used in most other countries. Converting between these units is a useful skill!

🧮 The Conversion Factor

The key to converting miles to kilometers is knowing the conversion factor:

1 mile is approximately equal to 1.60934 kilometers.

✏️ How to Convert Miles to Kilometers

To convert miles to kilometers, you multiply the number of miles by the conversion factor (1.60934).

Formula:

Kilometers = Miles × 1.60934

➕ Examples

Example 1: Convert 5 miles to kilometers.

Kilometers = 5 miles × 1.60934

Kilometers = 8.0467

So, 5 miles is approximately equal to 8.0467 kilometers.

Example 2: Convert 10 miles to kilometers.

Kilometers = 10 miles × 1.60934

Kilometers = 16.0934

So, 10 miles is approximately equal to 16.0934 kilometers.

💻 Code Example (Python)

Here's how you can do the conversion using a simple Python program:

def miles_to_kilometers(miles):
    kilometers = miles * 1.60934
    return kilometers

miles = 5
kilometers = miles_to_kilometers(miles)
print(f"{miles} miles is equal to {kilometers} kilometers")

miles = 10
kilometers = miles_to_kilometers(miles)
print(f"{miles} miles is equal to {kilometers} kilometers")
