How many kilometers is 100 miles in kilometers per hour?

To convert 100 miles per hour (mph) to kilometers per hour (km/h), we use the following conversion factor:

1 mile=1.60934 kilometers

Steps for Conversion:

1. Start with the given value in miles per hour:
   • You are given 100 miles per hour.
2. Multiply by the conversion factor:
   • To convert miles to kilometers, multiply by 1.60934 (the number of kilometers in one mile).

   100 miles per hour×1.60934=160.934 km/h

Result:

100 miles per hour is equal to 160.934 kilometers per hour.

Explanation:

The conversion factor of 1.60934 is used because it defines how many kilometers are equivalent to one mile. Since the relationship is linear, multiplying the number of miles by this factor gives you the corresponding value in kilometers.

Conclusion:

Thus, 100 mph is equivalent to approximately 160.93 km/h. This conversion is important when comparing speeds in different measurement systems, particularly in countries that use miles per hour (like the United States) and those that use kilometers per hour (like most countries worldwide).
