I think you have to become more prescie. What do you mean by logit measures? The predicted probabilities? What do you mean by 'in other data analysis software'? Which software do you use at the moment?
Logit is a unit of additive measurement which is well-defined within the context of a single homogeneous test.
When logit measures are compared between tests, their probabilistic meaning is maintained but their substantive meanings may differ. This is often the case when two tests of the same construct contain items of different types. Consequently, logit measures underlying different tests must be equated before the measures can be meaningfully compared. This situation is parallel to that in Physics when some temperatures are measured in degrees Fahrenheit, some in Celsius, and others in Kelvin.
