To calculate the ml/hour from drops/minute, you need to know the drop factor (drops/ml) of the IV set being used, which is commonly around 20 drops/ml for a standard adult set. Given the rate of 66 drops/minute, you convert this to an hourly rate by multiplying by 60 (minutes in an hour). So, 66 drops/minute * 60 minutes/hour = 3960 drops/hour. Then, to convert drops to ml, you divide by the drop factor: 3960 drops/hour / 20 drops/ml = 198 ml/hour.
