If you simply need to figure out the mL per hour to infuse, take the total volume in mL, divided by the total time in hours, to equal the mL per hour. For example, if you have 1,000 mL NS to infuse over 8 hours, take 1,000 divided by 8, to equal 125 mL/hr. To calculate the drops per minute, the drop factor is needed.
How do you calculate drug infusion rate?
This can be done in stages: To calculate the millilitres/hour we first need to work out what dose is contained in one millilitre of the infusion dosage. We can do this by dividing the volume of the dosage by the weight of the medicine it contains. In this case 500ml/500mg = 1ml/mg.
How do you calculate IV infusion time?
The formula to calculate how many hours will it take for the IV to complete before it runs out is: Time (hours) = Volume (mL) Drip Rate (mL/hour) . The volume of the fluid is 1 000 mL and the IV pump set at 62 mL/hour.
How do you convert units per hour to mL per hour?

How do I calculate flow rate?
Q=Vt Q = V t , where V is the volume and t is the elapsed time. The SI unit for flow rate is m3/s, but a number of other units for Q are in common use. For example, the heart of a resting adult pumps blood at a rate of 5.00 liters per minute (L/min).
How do you convert drops per minute to mL per hour?
Conversion chart – drops per minute to milliliters per hour
- drop per minute to milliliters per hour = 3.00 mL/h.
- drops per minute to milliliters per hour = 6.00 mL/h.
- drops per minute to milliliters per hour = 9.00 mL/h.
- drops per minute to milliliters per hour = 12.00 mL/h.
How do you calculate volume in mL?
The units of mass (weight) in the metric system are kilograms and grams. Once you know both the density and the mass, divide the mass by the density to find the volume. If you want to calculate volume in milliliters, measure the weight in grams.
How many drops is 100 mL per hour?

| 20 | 100 | |
|---|---|---|
| 10 DROP/ML | 3 | 16 |
| 15 DROP/ML | 5 | 25 |
| 20 DROP/ML | 6 | 32 |
How do you calculate drug calculations?
A basic formula, solving for x, guides us in the setting up of an equation: D/H x Q = x, or Desired dose (amount) = ordered Dose amount/amount on Hand x Quantity.
How do you convert mL to hours?
Please provide values below to convert milliliter/minute [mL/min] to milliliter/hour [mL/h], or vice versa.
Milliliter/minute to Milliliter/hour Conversion Table.
| Milliliter/minute [mL/min] | Milliliter/hour [mL/h] |
|---|---|
| 0.01 mL/min | 0.6 mL/h |
| 0.1 mL/min | 6 mL/h |
| 1 mL/min | 60 mL/h |
| 2 mL/min | 120 mL/h |
How much mL is an hour?
Equals: 60.00 milliliters per hour (mL/h) in flow rate.
How do you calculate flow rate in nursing?
To perform this calculation, you need to know the total volume to be infused in milliliters and the amount of time for the infusion. Use this formula: For example, if your patient needs 1,000 ml of fluid over 8 hours, find the flow rate by dividing the volume by the number of hours: The flow rate is 125 ml/hour.
How do you calculate unit per hour?
Rate (units/h) = Rate (mL/h) x Concentration of Additive (units/mL) = 20 mL/h x 50 units/mL = 1000 units/h The patient is receiving 1000 units of heparin every 1 hour.
How long does a 500 mL IV take?
We determined that the IV infusion will take 6.6667 hours to infuse 500 mL at 75 mL/hr.
How do you calculate IV fluids for adults?
The 24-hour number is often divided into approximate hourly rates for convenience, leading to the “4-2-1” formula.
- 100 ml/kg/24-hours = 4 ml/kg/hr for the 1st 10 kg.
- 50 ml/kg/24-hours = 2 ml/kg/hr for the 2nd 10 kg.
- 20 ml/kg/24-hours = 1 ml/kg/hr for the remainder.
How many mL is 5grams?
Gram to Milliliter Conversion Table

| 4 g | 4 ml | 5.7143 ml |
| 5 g | 5 ml | 7.1429 ml |
| 6 g | 6 ml | 8.5714 ml |
How do you convert units to mL?
Below is a conversion chart to help those who need to convert units of insulin to ml.
How to Convert Insulin Units to Milliliters (ml) Using U-100 Insulin.
| To administer this amount of U-100 insulin | Draw to this level in a 1 ml syringe |
|---|---|
| 1 unit | 0.01mls |
| 2 units | 0.02 mls |

How do you convert from liters to milliliters?
Multiply the number of liters (L) by 1,000 to find the number of milliliters (mL). There are 1,000 times as many milliliters as there are liters. For instance, say you have 3 liters. Simply multiply 3 liters by 1,000 to get 3,000 milliliters.
What is m3 per hour?
Cubic Meter Per Hour (m3/h) is a unit in the category of Volume flow rate. It is also known as cubic meters per hour, cubic metre per hour, cubic metres per hour, cubic meter/hour, cubic metre/hour, cubic meter/hr, cubic metre/hr, flowrate.
How do you calculate liquid flow in a pipe?
If the liquid is flowing through a pipe, the area is A = ?r2, where r is the radius of the pipe. For a rectangle, the area is A = wh where w is the width, and h is the height. The flow rate can be measured in meters cubed per second (m3/s), or in liters per second (L/s).
How many mL is a IV drop?
20 drops
Drop factor = the number of drops it takes to make up one ml of fluid. Two common sizes are: 20 drops per ml (typically for clear fluids)
