The formula is;
F = GMm/(25 mi)²
where "M" and "m" are the masses of the two objects, and "G" is the universal gravitational constant (about 6.67 * 10^-11 m^3/(kg•sec²)
To get a quick answer, use Google's built-in calculator: it already understands what "G" means. For example, if M=1000 kg and m=150 kg, you can type this into google:
G * 1000 kg * 150 kg / (25 mi)^2
That will give you the answer in "Newtons," the standard physics unit of force. To get the answer in "pounds," just type this:
G * 1000 kg * 150 kg / (25 mi)^2 in pounds

F = G m1 m2 / r^2
m1 = mass 1 in kg
m2 = mass 2 in kg
r = distance between the centers of mass in meters
G = gravitational constant
F = force in newtons
You'll either have to convert to the metric system to use this formula or find a G that works for the fps system

F = GmM/r2
where r is the distance.
you will need to use the proper units for "r" as the gravitational constant "G" dictates.
G = 6.67x10^-11 m^3/kgs^2
So you have to convert 25 miles to meters

f=Gmm'/r^2 where r = 25 miles. oh yes do not forget to convert miles to meters
