The most common is desired over have times quantity: divide the ordered dose by the dose on hand, then multiply by the volume or form it comes in. Dimensional analysis and ratio-proportion give the same answer and help check your working.

Multiply the volume in mL by the drop factor of the giving set in drops per mL, then divide by the time in minutes. For example, 1,000 mL over 8 hours with a 15 drops/mL set runs at about 31 drops per minute.
