Hello,

I am trying to help someone out with their homework and I've managed to help her with all kinds of metric conversions.

But now I am stuck.

The problem is convert 5.3 kg/L to g/cm^3

That's 5.3 kilograms per liter to grams per centimeter cubed.

I know there are a thousand grams in a kilogram and a thousand centimeters cubed in a liter, so would the answer be 5.3g/cm^3 ?

I'm not too sure about that. Thanks for anyone's help!!

The trick on all conversions is to set up a fraction with the old units in the denominator, and the ones you want in the numerator, thus:

1KG = 1000 g

1000 g X L
_________________ X 5.3 kg/L= 5.3 g/cm^3
KG X 1000cm^3

No matter how bad the conversion, pile enough fractions on so that original units cancel, and leave only the units you need.

Thanks very much!! She was trying to explain something that had to do with lines, and that is what you are referring to.

Thanks for helping us to figure it out!

Thanks for your quick response... Sarah thanks you, too.
