You see there are many formulas in obtaining force:
F=ma; m=mass a=acceleration
F=PA; P=pressure A=Area
and many more!
Try to read some books of Physics or Engineering Thermodynamics.
Because, as long as you can manipulate the given formula... Other formulas for forces wil arise.

All is based on Newton's 2nd law of motion..that the force applied to a given body is proportional to both mass and accerelation....In equation form, it is F = ma....You can measure force by getting the mass and acceleration or using an apparatus such as a spring scale....
But what kind of force is applied to the body? Is it weight? If so, F = mg.........Is it centripetal force? If so, F = mv^2/r ...Is it frictional force? Is so, F = u * F(normal)

There is no formula to measure force. Only to calculate it.

It is newtons 2nd law.
Which was originally in terms of momentum, but the conclusion of it is
F = ma
where m is mass, and a is accleration
weight is a force, where acceleration is that due to the earths gravity (a = g)
calculations are a method of finding the measure of something.
both words mean to quantify ...
