$kg*m/s^2$ or $N$
Work Step by Step
In order to know the base SI units for force, first recall the equation for force: $Force=Mass*Acceleration$. The units for acceleration are $distance/time^2$. The SI unit for distance is the meter, and the SI unit for time is the second. Thus the unit for acceleration is $meters/second^2$. The SI unit for mass is the kilogram. When the units for mass and for acceleration are multiplied together in the equation $Force=mass*acceleration$, it can be determined that the SI units of measurement for force are $kg*m/s^2$ also known as the $Newton (N)$.
