What do we use to measure weights nowadays? Grams. 1 gram is about the weight of one Skittle sweet. Instead of writing grams we often just write g. Kilograms. 1 kilogram is about the weight of a large dictionary. We write kg for kilograms.

Can I convert grams to kilograms and vice versa. To convert kilograms to grams, we multiply by To convert grams to kilograms, we divide by 1000.

To convert kilograms to grams, multiply by Move all the digits three places to the left, and add zeroes as placeholders. THHTU 9

To convert kilograms to grams, multiply by Move all the digits three places to the left, and add zeroes as placeholders. THHTU 1 7

To convert kilograms to grams, multiply by Move all the digits three places to the left, and add zeroes as placeholders. HthTthThHTU 128

To convert grams to kilograms, simply do it the other way. Move all the digits three places to the right and see what you’re left with. HthTthThHTU 6 000
