Scaling parameter for multi objective function

I have two objective functions, but the formulation of one function has larger numbers than the other function. Therefore, the first function is more impact on the result. Probably, I should put a scaling parameter for the functions so that they become the same unit. Is there a any formula or method to determine these scaling numbers?
a=[33.5106 34.9787 36.4468 38.3830 40.3404 42.5213 44.7234 39.6915 33.5745 15.3298 -5.4681 -39.6702 -77.5957

p(48) is variable 
obj 1: sum_square((( a+ p))
obj 2 : sum(0.004*(p^2)+0.075.*p+0.003)

And I think, for example, because the coefficient of the objective function 2 is 0.004, it makes its effect very low on result. So objs should be united somehow

If you choose a scaling so the optimal objective value is 1 or greater, then about 6 to 8 figures will be correct.

Why do square in

sum_square((( a+ p))

?

Minmize ||a+p||

is likely to be more stable.

I didn’t understand. if I set the weight to 8, will they be the same unit and their effect will be the same?

Not sure what you mean. However,

min f(x)

and

min 8*f(x)

has the same optimal x.
