You can calculate the corresponding values using Newton's Law of Gravitation:

[math]F = G*m1*m2/(r^2)[/math]

Remember to use G = 6.67E-11 N(m/kg)^2;

Here is an example:

Your mass (m1) = 60 kg, mass of nearby object like a car (m2) = 1000 kg, and distance between you two (r) = 1m.

Then, F = 4*(10^-6) N.

Now let the second object be the planet Mars (m2) = 6.4185*(10^23) kg, and the (average) distance between you two (r) = 225 million km.

Hence, F = 5.07*(10^-8) N

You can now directly compare the two results and see which one is more significant!
