To convert astronomical units (AU) to meters per second, you can use the conversion factor: 1 AU = 149,597,870,700 meters. If you need to convert a velocity in AU per year to meters per second, you would need to divide the AU per year value by the number of seconds in a year (31,556,952 seconds).
To convert 139 yards in 25.75 seconds to miles per hour, first calculate the speed in yards per second. Then convert yards to miles (1 mile = 1760 yards). Finally, convert seconds to hours (1 hour = 3600 seconds). Calculate the speed in miles per hour using the obtained values.
A parasecond is actually the long name of a parsec. The name originated in 1913 when light years were being used to measure distances to far away stars. The numbers were getting too high so a scientist (not sure which one) suggested a new unit named a parasecond (shortened to parsec) by combining he two words "parallax" and "arcsecond". Hence why any star with a parallax angle of 1 arcsecond is one parsec away. 1 parsec is roughly 3 light years.

To convert miles per hour to seconds, you need to know the distance covered in a specific time period. Miles per hour is a unit of speed, while seconds are a unit of time. Without additional information, it is not possible to directly convert 126 miles per hour into seconds.
To convert 4.4 miles per hour per second to meters per second squared, first convert 4.4 miles to meters (1 mile = 1609.34 meters) and 1 hour to seconds (1 hour = 3600 seconds). Then divide the speed in meters per second by the time in seconds squared to get the acceleration in meters per second squared.
1 year = 31,557,600 seconds convert x feet per year to y meters per year y/31,557,600 is the answer.
525,600 secs per year-multiply.
divide by 100,000
Your 1 kilometer equals 3.24077649 x 10-14 parsecs. And your second equals 3.16887646 x 10-8 years. Converting kilometers/second to parsecs/year involves multiplying by 3.24077649 x 10-14 and dividing by 3.16887646 x 10-8 to get your answer. Or do that bit of math in advance and then just multiply by 1.022689439 x 10-6 to get your answer. Make sure you have your beginning figure in km per one second. Your answer will appear in parsecs per one year, or just parsecs per year.
60 seconds per minute, times 60 minutes per hour = 3600 seconds, times 24 hours per day = 86,400 seconds, times 365 days per year = 31,536,000 seconds, times ten years per decades = 315,360,000 seconds. Close to a third of a billion.
To convert astronomical units (AU) to meters per second, you can use the conversion factor: 1 AU = 149,597,870,700 meters. If you need to convert a velocity in AU per year to meters per second, you would need to divide the AU per year value by the number of seconds in a year (31,556,952 seconds).
To convert seconds into hours, you divide the number of seconds by 3,600, since there are 3,600 seconds in one hour (60 seconds per minute multiplied by 60 minutes per hour). For example, to convert 7,200 seconds into hours, you would calculate 7,200 ÷ 3,600, which equals 2 hours.
k seconds per mile = 3600/k miles per hour.
To convert 139 yards in 25.75 seconds to miles per hour, first calculate the speed in yards per second. Then convert yards to miles (1 mile = 1760 yards). Finally, convert seconds to hours (1 hour = 3600 seconds). Calculate the speed in miles per hour using the obtained values.
300 feet per 2.92 seconds = ~70.05 (70.0498132) mph
Multiply by seconds.
Multiply miles per second by 31,556,926 to convert to miles per year.
