How many kilograms in 109 grams?
Remember K H D | d c m (kilo, hecto, deka, (liter, meter, gram),
deci, centi, milli). These are the denominations you need to list
when converting metric units. Kilograms are three places to the
left of grams. So you have to move the decimal place three times to
the left (same as dividing by 1000). You will get 109 g = .109
kg.
