Is there a naming convention for attribute types whose SYNTAX is INTEGER?

If I wish to represent 300g as a weight, should I use

ibmWeightInGrams: 300

or ibmWeightInGRam: 300

or ibmGrams: 300

or ibmGram: 300

What is the convention way? There seems to be no INTEGER attribute types shipped with openldap, thus I have no references.

In my use case, ordered comparison of integer value is required, thus I cannot use:

ibmWeight: 300g
