Kilometres per hour to Miles per hour conversion

How to convert kilometres per hour to miles per hour?

To convert kilometres per hour (km/h) to miles per hour (mph), you can use the following conversion factor:

1 mile ≈ 1.60934 kilometres

Therefore, to convert $\text{km/h}$ to $\text{mph}$, you can use the formula:

$\text{mph} = \frac{\text{km/h}}{1.60934}$

For 1 kilometre per hour:

$1 \text{ km/h} = \frac{1 \text{ km/h}}{1.60934} \approx 0.621371 \text{ mph}$

So, 1 kilometre per hour is approximately 0.621371 miles per hour.

More Examples

1. 50 km/h:

$50 \text{ km/h} = \frac{50}{1.60934} \approx 31.07 \text{ mph}$

2. 100 km/h:

$100 \text{ km/h} = \frac{100}{1.60934} \approx 62.14 \text{ mph}$

3. 120 km/h:

$120 \text{ km/h} = \frac{120}{1.60934} \approx 74.56 \text{ mph}$

Real World Examples

1. Urban Driving Speed:

   • A typical urban speed limit might be 50 km/h.
   • In miles per hour, this would be approximately 31.07 mph.

2. Highway Speed Limit:

   • On many highways, the speed limit might be 100 km/h.
   • This is about 62.14 mph.

3. Fast Train Speeds:

   • Some high-speed trains can travel at speeds of up to 300 km/h.
   • This converts to approximately 186.41 mph.

4. Cycling Speed:

   • A moderate cycling speed for an average person might be 25 km/h.
   • This would be about 15.53 mph.

These conversions are useful for understanding speed limits and travel times in different countries that utilize different units of measure.
