The SI unit used to measure force is the newton (symbol N), which is equivalent to kg·m·s−2. (The earlier CGS unit is the dyne)

SI units are kg-m-sec. Since force = f = ma; the units of force are mass (kg) and acceleration (m/sec^2). Thus, the units for force are kg-m/sec^2, which is given a physically meaningless name called Newton.
Terms like Newton, Pound, dyne, and such are of little help in conducting unit analysis to ensure a derived answer is correct, at least from the point of view of its units. But look what you can do with true SI units like kg, m, and sec. If f = ma and your answer is 2 kg-m/sec after you've done the units analysis, you have to suspect your answer is incorrect. Why? Because m/sec is velocity, not acceleration and f = ma has an acceleration factor, not velocity.
All those other answers are pretty much OK. But if I were you, I'd avoid using Newton, pound, etc. and keep to the meaningful and useful kg-m-sec or g-cm-sec units when doing physics problems.

Unit for force is a Newton. See wikipedia, that site has awesome answers for everything.
Force is mathematically defined as the rate of change of the momentum of the body. Since momentum is a vector quantity (has both a magnitude and direction), force also is a vector quantity.

unit for force is Newtons in SI systems. to arrive this remember force is= pressure *area . Therefore newtons/metersquare multiplied by meters square, so both metersquares get cancelled and you will get newtons.
the dimension for Force is ML^-2

from newton's second law of motion f=ma .The unit of mass is kg and the unit of acceleration is m/s.s.So ma would result kgm/s.s.In short these is called newton N.

Metric is Newton, English is Pound. (The English mass unit is actually a slug.)
