(miles/hr)*(1/3600)=miles/sec Here is a method to convert units that you can adapt to any conversion: (miles/hr)*(1hr/60min)*(1min/60secs) All I have down here is multiply by fractions that equal 1, except the top and the bottom are in different units. As you can see the hr and min unit drop out and you are left with miles/sec

You can't convert meters per second per second to miles per hour, because miles per hour is a velocity unit and meters per second per second is a acceleration unit.

If you meant meters per second:

9.81 m/s ≈ 21.9 miles per hour The 9.81 meters per second squared is a unit of acceleration where as the mph is a unit of velocity.

They really don't relate other than the acceleration is the derivative of velocity

If you wanted to find out miles per hour squared you would do the following:

(9.81m/s2) * (3600s/1h)2 * (1mile/1609.344m) = around 79,000 mile/h2

Big number, huh???

(299792458meter/second) * (1mi/1609.34meter) * (60second/1min) * (60min/1hr)

= 670618296 mph

Divide by 3600 or multiply by 0.00277777 repeating

Use this conversion: mph x 0.0003 = miles per second

  • So, 18,000mph = 18,000 x 0.0003 = 5 miles per second
