Weight is how heavy something is. The standard forms of measuring lengths are: tones (t), kilograms (kg), and grams (g). To measure the weight of something use scale, and balancing scale.
If a person knows the weight of 9 pencils they can compare it with a scale or a balancing scale, and if they know the weight of the pencils they can estimate it.
To turn grams to kilograms it has to be divided by one thousand, and to turn kilograms to tones it has to be divided by one thousand.
