Memorize this and you'll be able to do ALL of these: 1 kg = 1,000 g
So if you have some grams, divide the number by 1,000 to get kilograms.
1,000 g = 1.000 kg
500 g = 0.500 kg
100 g = 0.100 kg
50 g = 0.050 kg
20 g = 0.020 kg
10 g = 0.010 kg
To convert grams to kilograms, divide the mass in grams by 1,000. For example, 1,000 grams is 1.000 kilograms, while 500 grams is 0.500 kilograms. This conversion is applicable to all values given in the table.
