### 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.
