Seconds per foot to Minutes per kilometre conversion

How to convert seconds per foot to minutes per kilometre?

To convert from seconds per foot (s/ft) to minutes per kilometer (min/km), you can follow these steps:

1. Convert feet to meters: 1 foot = 0.3048 meters

2. Convert seconds per foot to seconds per meter: Since 1 foot is 0.3048 meters, you can express the conversion as: $\text{Seconds per meter} = \frac{\text{Seconds per foot}}{0.3048}$

3. Convert seconds per meter to seconds per kilometer: 1 kilometer = 1000 meters, so: $\text{Seconds per kilometer} = \text{Seconds per meter} \times 1000$

4. Convert seconds per kilometer to minutes per kilometer: 1 minute = 60 seconds, so: $\text{Minutes per kilometer} = \frac{\text{Seconds per kilometer}}{60}$

Putting it all together to convert 1 second per foot to minutes per kilometer:

1. Seconds per meter: $\text{Seconds per meter} = \frac{1}{0.3048} \approx 3.2808 \text{ s/m}$

2. Seconds per kilometer: $\text{Seconds per kilometer} = 3.2808 \times 1000 = 3280.8 \text{ s/km}$

3. Minutes per kilometer: $\text{Minutes per kilometer} = \frac{3280.8}{60} \approx 54.68 \text{ min/km}$

So, 1 second per foot is approximately 54.68 minutes per kilometer.

Real World Examples

1. Walking Pace:

   • A moderate walking pace is around 20 minutes per mile (around 1.24 s/ft).
   • Converted: $\text{Seconds per meter} = \frac{1.24}{0.3048} \approx 4.068 \text{ s/m}$ $\text{Seconds per kilometer} = 4.068 \times 1000 = 4068 \text{ s/km}$ $\text{Minutes per kilometer} = \frac{4068}{60} \approx 67.8 \text{ min/km}$

2. Running Pace:

   • A typical running pace may be around 9 minutes per mile (around 0.56 s/ft).
   • Converted: $\text{Seconds per meter} = \frac{0.56}{0.3048} \approx 1.837 \text{ s/m}$ $\text{Seconds per kilometer} = 1.837 \times 1000 = 1837 \text{ s/km}$ $\text{Minutes per kilometer} = \frac{1837}{60} \approx 30.62 \text{ min/km}$

3. Marathon Goal Pace:

   • An average marathon pace might be around 4 minutes per kilometer (0.12 s/ft).
   • Converted: $\text{Seconds per meter} = \frac{0.12}{0.3048} \approx 0.394 \text{ s/m}$ $\text{Seconds per kilometer} = 0.394 \times 1000 = 394 \text{ s/km}$ $\text{Minutes per kilometer} = \frac{394}{60} \approx 6.57 \text{ min/km}$

These conversions help you to understand how different paces measured in seconds per foot translate into minutes per kilometer, which is a more commonly used unit in many parts of the world for running and walking.
