What is the formula for drop factor?

Keep in mind:

Drop Factor - (gtt/mL) - This varies depending on the tubing / IV equipment.
Flow Rate - (gtt/minute) - This will manually regulate the IV volume.

The formula is generally this:

IV Volume (mL)
----------------------- X Drop Factor (gtt/mL) = Flow Rate (gtt/Minute)
Time (minutes)

This formula is most common because questions are usually asking what the flow rate should be set to.
