Problem:
How many grams are in an eighth of a kilogram?
Solution:
There are 1000 grams in 1 kilogram.
Set up the conversion so the desired unit will be cancelled out. In this case, we want g to be the remaining unit.
Mass in g = (mass in kg ) x (1000 g/1 kg)
Note how the kilograms unit will be cancelled out in this equation.
Mass in g = (1/8 kg) x 1000 g/kg
Mass in g = (0.125 kg) x 1000 g/kg
Mass in g = 125 g
Answer:
There are 125 grams in an eighth of a kg.
