Conversion Formula
The formula to convert miles per hour (mph) to kilometers per hour (km/h) multiplies the mph value by 1.609344. This number is derived from the exact distance of one mile in kilometers. The calculation works because 1 mile equals 1.609344 km, so the conversion directly scales the speed.
For example, if you want to convert 5 mph, you multiply 5 by 1.609344: 5 x 1.609344 = 8.04672 km/h. This step-by-step method ensures precise translation from miles to kilometers per hour, based on the exact mile-to-kilometer relationship.
Conversion Example
- Convert 2 mph:
- Multiply 2 by 1.609344
- 2 x 1.609344 = 3.218688 km/h
- The speed is about 3.2187 km/h
- Convert 4.5 mph:
- Multiply 4.5 by 1.609344
- 4.5 x 1.609344 = 7.242096 km/h
- The speed is approximately 7.2421 km/h
- Convert 10 mph:
- Multiply 10 by 1.609344
- 10 x 1.609344 = 16.09344 km/h
- The speed is about 16.0934 km/h
- Convert 0.5 mph:
- Multiply 0.5 by 1.609344
- 0.5 x 1.609344 = 0.804672 km/h
- The speed is around 0.8047 km/h
