Before diving into the conversion, it is important to understand the fundamental principles behind the metric and imperial systems for measuring length.
The Metric System
The metric system is based on a decimal system of multiples and fractions of ten. Length is measured in the standardized base unit of meters (m). Larger lengths are measured in kilometers (km), where:
1 kilometer = 1,000 meters
Some key advantages of using the metric system include:
- Standardized base units are used across measurements
- Easily convert between units by multiplying or dividing by powers of 10
- Considered simpler and more logical to use in calculations
The metric system is widely used for measurement across science, math and everyday use around the world.
The Imperial System
Imperial units originated in Britain and are still used regularly in the United States. Length is measured in the base unit of feet (ft) or inches (in). Larger distances are measured in miles (mi), where:
1 mile = 1,760 yards = 5,280 feet
The imperial system may lead to more complex conversions since the system contains many non-decimal units. However, supporters argue imperial units are more familiar, especially for describing height and shorter distances.
Now that we have refreshed our understanding of metric and imperial units, we can dive into the step-by-step kilometers to miles conversion.
How to Convert 1.4 km to Miles
We will work through the kilometer to mile conversion in 5 easy-to-follow steps:
Step 1) Recall the Kilometers to Miles Conversion:
1 km = 0.62137 mi
This essential conversion ratio tells us 1 kilometer equals 0.62137 miles. Knowing this Ratio is key for all km to mi conversions.
Step 2) Set up the Unit Conversion:
Start by writing out the units you have (kilometers) and the units you want to convert to (miles). Build up your conversion like this:
1.4 kilometers (km) = ? miles (mi)
Step 3) Plug the Conversion Factor into Your Setup:
We know from Step 1 that:
1 km = 0.62137 mi
So plug this into your unit conversion setup:
1.4 km x (0.62137 mi / 1 km) = ? mi
Step 4) Perform the Arithmetic:
Multiply the values straight across and simplify:
1.4 km x (0.62137 mi / 1 km) = 0.86993 mi
We can round this to 0.87 miles.
Step 5) Confirm Your Answer
Double check your math by working back from miles to km using the reverse conversion:
0.87 miles x (1 km / 0.62137 mi ) = 1.4 km
Our answer is verified!
There we have it – a step-by-step guide on converting 1.4 km into 0.87 mi. With some practice, you’ll find unit conversions getting much easier.
Kilometers to Miles Formula
For those seeking a shorthand kilometer to mile formula, use:
Miles = Kilometers x 0.62137
Simply plug in the kilometers value and multiply by 0.62137 to convert directly to miles.
So for our example:
Miles = 1.4 km x 0.62137 = 0.87 miles
This shortcut formula builds the entire conversion process into one simple multiplication equation.
Converting Other Kilometer Values to Miles
Now that you understand the fundamentals of converting kilometers to miles, let’s put our knowledge into practice by converting some other common km values into miles:
1 km to miles
Following the steps we just learned:
1 km x (0.62137 mi/1 km) = 0.62137 miles
5 km to miles
5 km x (0.62137 mi/1 km) = 3.1069 miles
10 km to miles
10 km x (0.62137 mi/1 km) = 6.2137 miles
I hope these examples help reinforce the straightforward process used for all kilometers to miles conversions. With some practice, you’ll be able to effortlessly convert any km measurement into miles.
Why Convert Kilometers to Miles?
Before we wrap up, you may be wondering – in what situations should I convert between kilometers and miles? Here are some top reasons for making km to mi conversions:
- Travel Planning – When planning an international trip, converting km values for travel distances to familiar miles helps better visualize the journey.
- Training Programs – Athlete training programs often involve distance measurements. Converting program metrics avoids confusion between metric and imperial units.
- Vehicle Efficiency – MPG fuel efficiency ratings often use different units globally. Converting all figures to say MPG simplifies efficiency comparisons.
Whatever your reasons for needing to switch between kilometers and miles, I hope this guide gives you the knowledge and tools to carry out these conversions with ease.

Frequently Asked Questions
How do you quickly convert km to miles in your head?
To quickly estimate km to miles conversions:
Round the km figure to a simpler value. For example, round 1.4 km to 1 km.
Then multiply the simplified km value by 0.6. This will provide an approximate mile estimate.
So for 1.4 km, estimate using 1 km x 0.6 = 0.6 miles
The exact conversion is 0.87 miles, so our estimate is reasonably accurate.
Is a km shorter or longer than a mile?
A kilometer is shorter than a mile. Precisely, 1 kilometer equals 0.62137 miles. So a mile is about 1.6 times longer than a kilometer. Keeping their different lengths straight will avoid conversion errors.
How many kilometers are in a marathon?
A marathon measures 26.219 miles. Using our handy conversion formula:
Miles = Kilometers x 0.62137
We can calculate marathon kilometers as:
26.219 miles / 0.62137 = 42.195 km
So a marathon race covers 42.195 kilometers. Now you can directly compare marathon results in miles or kilometers!
