This free conversion calculator will convert miles per hour to kilometers per hour, i.e. mph to km/h. Correct conversion between different measurement scales.

The formula is $$$S_{\frac{km}{h}} = 1.609344 S_{\text{mph}}$$$, where $$$S_{\text{mph}} = 15$$$.

Therefore, $$$S_{\frac{km}{h}} = 24.14016$$$.

Answer: $$$15 \text{mph} = 24.14016 \frac{km}{h}$$$.
