kg/s m^3/s L/m^3 kg/m^3
I gave my students this multiple choice question: A researcher is measuring changes in the density of the upper atmosphere over time. Which units should be used for the density measurements?

Only one answer is correct among these 4 choices:
- kg/s
- m^3/s
- L/m^3
- kg/m^3

Could you tell me which one is correct?

kg/m^3
