I just calculated interns' hours as full-time equivalent (FTE) employees. If you're not familiar with this, it means adding up all their hours per week and dividing by 40 (for a 40-hour work week), which can give you the equivalent number of full-time employees.

Here's a graph of my FTE intern management experience over time:
