# How do you convert 100 g to kg?

$100$ g is equal to $0.1$ kg.
There are $1000$ grams in one kilogram, so to convert grams to kilograms, you simply divide the number of grams by $1000$. Technically, this is "unit conversion" and looks like this in fully expanded form:
$100 g \cdot \frac{1 k g}{1000 g} = \frac{100 g \cdot k g}{1000 g} = 0.1 k g$
