Well, yes and no. Let's say you have a simple project with a timeline of one month. If a single resource is assigned at 100% (i.e. full time), Project will calculate 160 hours of work. If a single resource is assigned at 50% (i.e. half time), Project will calculate 80 hours of work.
However, if you simply have a timeline describing a total span of time for one or more tasks, Project will not assume that represents a given number of man hours. There are too factors that play into a plan to give a simple answer to timeline versus man hours.
If you can explain in more detail what you are trying to accomplish, then we can be of further help.

Thank you! So we have numerous upcoming projects (as well as current ongoing projects) with start and finish dates, so we want all those on a schedule, trying to determine how many man hours we will need for projects, ultimately being able to determine if we need to hire more people. I hope that makes sense

It sounds like you are approaching this at too high a level since you are talking about "projects". Normally a project is a collection of activities (tasks) linked together in a logical sequence to achieve an end goal. If all you have at this point is the start and desired finish of a "project" (i.e. single timeline), then the best you can do for a manpower estimate is to compare it with similar projects that were completed and perhaps apply educated guess adjustment factors.
In order to get a better and more realistic manpower estimate, each project must be broken down into the sequence of tasks mentioned above. Given that, if you know the estimated time span (duration) for each task and the estimated manhours to accomplish each task, you could set Project's task type to "fixed duration", enter the duration and work and then assign an arbitrary resource. Project will calculate the required number of resources required. for example, in the following example the "project" consists of four tasks in logical sequence, each with an estimated duration and work content. When the "people" resource is assigned, Project calculates the assignment level required. The assignment level is shown in the Resource Name field as a percentage of a full time work resource. The level of course varies over the total project timeline but in this example, 2 people will be needed for the last task.
This is a very simplified example to what is a complex process but it might be useful as a first draft approach.
