Converting from Minutes per Foot (mpf) to Speed of Sound in Air (ssia)

What is Minutes per foot (mpf)

Minutes per foot (mpf) is a unit used to describe the time taken to travel one foot. It is commonly utilized in various fields such as engineering, aviation, and maritime navigation. The lower the number of minutes per foot, the faster the speed, as it indicates less time taken for each foot traveled.

What is Speed of sound in air (ssia)

The speed of sound in air (ssia) refers to the speed at which sound waves propagate through the air. This speed can vary based on temperature, humidity, and air pressure but generally averages around 343 meters per second (m/s) at room temperature (20 degrees Celsius). Understanding ssia is essential in disciplines such as acoustics, meteorology, and aerodynamics.

Conversion Formulas

To convert from minutes per foot (mpf) to speed of sound in air (ssia), you can use the following formula:

Conversely, to convert speed of sound in air (ssia) to minutes per foot (mpf):

Examples

1. For the conversion of 1 mpf to ssia:

   ssia=1×0.00001492844=0.00001492844ssia

2. For the conversion of 2 mpf to ssia:

   ssia=2×0.000007464222=0.000007464222ssia

3. To convert 11 mpf to ssia:

   ssia=11×0.000001357131=0.000001357131ssia

4. For 14 mpf to ssia:

   ssia=14×0.000001066317=0.000001066317ssia

5. Converting from ssia back to mpf, if you have a speed of sound at 0.00001492844 ssia:

   mpf=0.000014928441​≈1mpf

6. For a speed of 0.000007464222 ssia to mpf:

   mpf=0.0000074642221​≈2mpf
