Kilometers per hour (kph) and miles per hour (mph) are two different ways to measure speed. If you’re traveling abroad, you might need to convert between the two to understand speed limits. 120 kph is a pretty common speed, so let’s break down how to convert 120 kph to mph.
What are kilometers per hour (kph) and miles per hour (mph)?
You’re probably familiar with miles per hour (mph) as a way to measure speed. It tells you how many miles something will travel in an hour. The United States and the United Kingdom are the primary countries that use miles per hour.
Many other countries use kilometers per hour (kph), which tells you how many kilometers something will travel in an hour.
How to convert 120 kph to mph
To convert kilometers per hour (kph) to miles per hour (mph), you can use this formula:
mph = kph × 0.621371
In this formula, 0.621371 is the conversion factor.
So, if you want to convert 120 kph to mph, the equation looks like this:
120 kph × 0.621371 = 74.56452 mph
Therefore, 120 kph is about 74.56 mph.
You can also use this formula:
mph = kph / 1.609344
When is this conversion useful?
Knowing how to convert kilometers per hour to miles per hour is useful in lots of situations. For example, if you travel abroad, you’ll need to understand speed limits posted in kph. You might also want to compare the speeds of different vehicles when the manufacturers use different units.
Misunderstanding speed limits because of unit differences can be dangerous. That’s why it’s so important to get the conversion right.
Here’s a tip: if you need to quickly estimate mph from kph, just multiply the kph number by 0.6. It’s not exact, but it’s close!
