Converting from Seconds per mile (spm) to Seconds per kilometer (s/km) in Speed

What is Seconds per mile (spm)

Seconds per mile (spm) is a unit of measurement that indicates the time, in seconds, it takes to cover one mile while moving at a certain speed.

What is Seconds per kilometer (s/km)

Seconds per kilometer (s/km) is a unit that represents the time, in seconds, required to cover one kilometer at a particular speed.

Conversion Formulas

The default conversion between spm and s/km is as follows:

• 1 (spm) = 0.6213712 (s/km)
• 1 (s/km) = 1.609344 (spm)

To convert spm to s/km or vice versa, you can use the following formulas:

• s/km=spm×1.609344

• spm=s/km×0.6213712

Examples

1. Converting 7 spm to s/km:
   • 7 spm = 7 x 0.6213712 = 4.349598 s/km
2. Converting 16 s/km to spm:
   • 16 s/km = 16 x 1.609344 = 25.7495 spm
3. Converting 12 spm to s/km:
   • 12 spm = 12 x 0.6213712 = 7.456454 s/km

Use the provided conversions to seamlessly convert between Seconds per mile (spm) and Seconds per kilometer (s/km) in your speed calculations.
