# Is it possible to convert kg/(kWh) to litres/100m ?

 P: 37 kg/kWhour into litres/100m? is this possible, and if so how? what happens to the hour?
 HW Helper Sci Advisor P: 4,281 I would be more curious what happens to the kW and the meters. Do you have a specific system in mind? Or do you want to do the conversion by using physical constants (such as c and hbar), because then I think it is not possible (kg/kWh ~ s / m^2 while l/m ~ m^2).

Close.

What CompuChip is talking about is dimensional analysis. kg/kWh has dimensions of time2/length2, while liters/meter has dimensions of length2.

You can only convert from one form to another if both forms have the same dimensions. For example, you can convert from miles per hour to meters per second because both are in the form of length/time. There is no conversion from kg/kWh to liters/meter because the two forms are incommensurable.
