You can also enter units that are combinations of other units. Keep in mind that you have to indicate the multiplication of units explicitly either with a multiplication dot or a dash. You can add a multiplication dot by selecting the dot from the Templates menu. The weight of an object is the product of its mass, m, and the acceleration of gravity, g (where g=9.8 m/s2). If an object’s mass is m=10. kg, what is its weight?
