This is the formula I've always used, hope it helps.
Step 1: Determine the concentration of Pitocin/mL:
1 unit = 1,000 miliunits
10 units = 10,000 miliunits
10,000 miliunits = 10 miliunits (10 miliunits/1 mL)
1,000 mililiters 1 mililiter
Step 2: Calculate (at this concentration) how many mL/hour will be given:
1 miliunit/minute = 60 milliunits/hour (1 miliunit X 60 minutes/hour)
Step 3:Using ratio & proportion to calculate mL/hour:
10 miliunits:1 mL = 60 miliunits: X mL
10X = 60
X = 6 mL/hour
