Converting from Speed of Sound in Air (ssia) to Seconds per Mile (spm)

What is Speed of Sound in Air (ssia)

The Speed of Sound in Air (ssia) refers to the speed at which sound waves travel through the atmosphere. At sea level and at a temperature of 20 degrees Celsius, this speed is approximately 343 meters per second. This measurement is critical in various fields such as meteorology, aviation, and sound engineering.

What is Seconds per Mile (spm)

Seconds per Mile (spm) indicates the time it takes to travel one mile. This unit is often used in running and cycling contexts to measure performance. For example, if a runner completes a mile in 6 minutes, their pace is referred to as 360 seconds per mile.

Conversion Formulas

To convert between these two units, the following formulas are used:

• To convert from Speed of Sound in Air (ssia) to Seconds per Mile (spm):

  spm=ssia1​×4.729331

• To convert from Seconds per Mile (spm) to Speed of Sound in Air (ssia):

  ssia=spm1​×4.729331

Where:

• 1 (ssia) = 4.729331 (spm)
• 1 (spm) = 4.729331 (ssia)

Examples

1. Convert 1 ssia to spm:

   spm=1×4.729331=4.729331

2. Convert 14 ssia to spm:

   spm=14×4.729331=66.25163

3. Convert 5 spm to ssia:

   ssia=5×4.729331=23.646655

4. Convert 7 ssia to spm:

   spm=7×4.729331=33.1243

5. Convert 14 spm to ssia:

   ssia=14×4.729331=66.25163

6. Convert 5 ssia to spm:

   spm=5×4.729331=23.646655

7. Convert 7 spm to ssia:

   ssia=7×4.729331=33.1243
