How many drops are in 1 mL of IV fluid?

Most macro sets are either 10, 15 or 20 drops to make 1 mL. The other drip set is a micro set, and it either takes 45 or 60 drops to make 1 mL. When giving most medications via continuous infusion, micro drip sets are the preferred method. One easy way to differentiate the two is by looking into the drip chamber.
