While attempting to do some formulas for the Hubble Constant (H0) I ran into difficulty with Units. Am I doing something wrong?:
This works:
UnitConvert["Meters","Mpc"]
This doesn't:
UnitConvert["Seconds"^-1,"Kilometers"/"Seconds"/"Mpc"]
Quantity::unkunit: Unable to interpret unit specification (Kilometers)/(Mpc Seconds).
