# Just a SI conversion question

How do I go about converting kg/cm^3 to kg/m^3? From g/cm^3 to kg/m^3 too. I am sure this is very easy but I can't find how to do it anywhere.

Thanks

Use dimensional analysis, like so:

kg/cm^3 to kg/m^3
$$\frac{kg}{cm^3} \times \left ( \frac{100 cm}{m} \right )^3 = \frac{kg}{m^3}$$

When both the numerator and denominator change, just repeat the process of canceling out units until you get to where you want to be.

The best resource for changing units (despite dimensional analysis) is google.

You can search for "convert 100cm^2 to m^2" and such for almost anything in math, science, and money conversions
