If 1 liter of IV fluid is infused over 4 hours, what is the infusion rate in mL/hr?

Infusion rate is the volume delivered divided by the time over which it’s given. Start by converting the volume to milliliters: 1 liter equals 1000 milliliters. Then divide by the duration: 1000 mL ÷ 4 hours = 250 mL per hour. This rate times the 4 hours equals the total volume (250 mL/hr × 4 hr = 1000 mL), confirming the calculation.
