Just like Planned Hours has a work and workRequired option, it looks like Actual Hours similarly have an actualWork and actualWorkRequired options.
When I send an API call looking for work and workRequired, what I get back is in hours and minutes based on the option. Likely the same thing goes for Actual Hours. Attaching a screenshot of a task with half an hour on the planned hours field. Edited to add that this is more relevant on the fusion side of things, as the field you pull in and want to transform will be in a particular format that you will want to keep in mind when you act on it.
