The conversion of 80 miles per hour (mph) to kilometers per hour (kph) results in 128 kph. This means that traveling at 80 mph is equivalent to moving at 128 kilometers each hour.
To convert mph to kph, multiply the speed value by 1.6 because 1 mile equals approximately 1.6 kilometers. For example, 80 mph multiplied by 1.6 gives 128 kph, confirming the conversion factor’s accuracy.

Conversion Formula
The formula converting mph to kpm is multiplying the mph value by 1.6. This works because 1 mile equals approximately 1.6 kilometers, so to get kilometers per hour, you simply scale up the miles per hour by this factor. For example, for 80 mph: 80 × 1.6 = 128 kph.
Conversion Example
- Convert 50 mph to kph:
- Multiply 50 by 1.6.
- 50 × 1.6 = 80.
- So, 50 mph is 80 kph.
- Convert 100 mph to kph:
- 100 times 1.6.
- 100 × 1.6 = 160.
- Thus, 100 mph equals 160 kph.
- Convert 65 mph to kph:
- Multiply 65 by 1.6.
- 65 × 1.6 = 104.
- Therefore, 65 mph is 104 kph.
- Convert 90 mph to kph:
- 90 times 1.6.
- 90 × 1.6 = 144.
- So, 90 mph is 144 kph.

Conversion Definitions
mph
mph, or miles per hour, measures how many miles an object travels in one hour, used mainly in the United States and the UK for speed limits and vehicle speeds.
kpm
kpm, or kilometers per hour, indicates the distance in kilometers traveled within one hour, commonly used internationally to specify vehicle speeds and transportation metrics.
Conversion FAQs
Why is mph multiplied by 1.6 to get kph?
This multiplication is based on the conversion factor where 1 mile equals approximately 1.6 kilometers. Thus, to convert mph to kph, multiplying by 1.6 provides the correct speed in kilometers per hour.
Can I use 1.61 instead of 1.6 for more accuracy?
Yes, using 1.61 gives a slightly more precise conversion, but for most practical purposes, 1.6 is sufficiently accurate. The difference is minimal and often negligible for everyday speed conversions.
Is the conversion factor the same for all speeds?
Yes, the factor of 1.6 applies universally for converting mph to kph regardless of the specific speed, because it’s based on the fixed length relationship between miles and kilometers.
How do I convert 80 kph back to mph?
To reverse the process, divide the kph value by 1.6. So, 80 divided by 1.6 equals 50 mph, showing the original speed in miles per hour.
