Grams (g) and kilograms (kg) are the two most common units of mass in the metric system.
It’s easy to convert grams to kilograms by cancelling units:
Another way to convert g to kg is to simply move the decimal point three spaces to the left. So, for 1536 g becomes 1.536 kg.
Kilograms to Grams Conversion
This example problem illustrates the method to convert kilograms to grams.
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.
When you convert kilograms to grams, all you need to do is move the decimal point three spaces to the right. This is essentially multiplying by one thousand.
