Conversion Formula
The formula to convert miles per hour to kilometers per hour is mph multiplied by 1.60934. This conversion factor is based on the exact length of a mile in kilometers, making the calculation straightforward. For example, converting 100 mph:
- 100 mph x 1.60934 = 160.934 km/h
This formula works because 1 mile equals 1.60934 kilometers, so multiplying the speed in mph by this factor gives the speed in kmh. It ensures accurate conversions when changing from imperial to metric speed units.
Conversion Example
Let’s convert 60 mph to kmh:
- Step 1: Take the value 60 mph.
- Step 2: Multiply 60 by 1.60934.
- Step 3: 60 x 1.60934 = 96.5604 km/h.
- Step 4: Result is 96.5604 kmh, which is the converted speed.
Another example, converting 45 mph:
- Step 1: Use 45 mph.
- Step 2: Multiply 45 by 1.60934.
- Step 3: 45 x 1.60934 = 72.4203 km/h.
- Step 4: The speed in kmh is 72.4203.
