Kilometres per hour to Feet per second conversion

How to convert kilometres per hour to feet per second?

Sure, to convert from kilometers per hour (km/h) to feet per second (ft/s), you can use the following steps:

1. Understand the basic conversions:

   • 1 kilometer = 1000 meters
   • 1 hour = 3600 seconds
   • 1 meter = 3.28084 feet

2. Set up the conversion for 1 km/h:

$1 \text{ km/h} = \left( \frac{1000 \text{ meters}}{1 \text{ hour}} \right) \left( \frac{1 \text{ hour}}{3600 \text{ seconds}} \right) \left( \frac{3.28084 \text{ feet}}{1 \text{ meter}} \right)$

3. Combine and simplify the units:

$1 \text{ km/h} = \frac{1000 \times 3.28084}{3600} \text{ feet/second}$

4. Perform the multiplication and division:

$1 \text{ km/h} ≈ 0.911344 \text{ ft/s}$

So, 1 kilometer per hour is approximately 0.911344 feet per second.

Real World Examples for Other Quantities of Kilometers per Hour:

1. Walking Speed:

   • Common walking speed is about 5 km/h.
   • Converting to feet per second: $5 \text{ km/h} = 5 \times 0.911344 \text{ ft/s} ≈ 4.55672 \text{ ft/s}$

2. Cycling Speed:

   • Average cycling speed is around 20 km/h.
   • Converting to feet per second: $20 \text{ km/h} = 20 \times 0.911344 \text{ ft/s} ≈ 18.22688 \text{ ft/s}$

3. Car Speed:

   • Urban speed limit might be around 50 km/h.
   • Converting to feet per second: $50 \text{ km/h} = 50 \times 0.911344 \text{ ft/s} ≈ 45.5672 \text{ ft/s}$

4. Freeway Speed:

   • Typical freeway speed could be about 100 km/h.
   • Converting to feet per second: $100 \text{ km/h} = 100 \times 0.911344 \text{ ft/s} ≈ 91.1344 \text{ ft/s}$

5. High-Speed Train:

   • High-speed trains might travel at around 300 km/h.
   • Converting to feet per second: $300 \text{ km/h} = 300 \times 0.911344 \text{ ft/s} ≈ 273.4032 \text{ ft/s}$

These examples help illustrate the conversion of various common speeds from kilometers per hour to feet per second.
