Why is matter measured in mass and not weight?

Matter is measured in mass and not weight because

W=mg

Where m is mass and g is acceleration due to gravity

So we measure matter in mass because it only occupies space and there is no affect of acceleration due to gravity on it

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
