Pediatric Dose Calculator
The pediatric dose calculator is a simple tool for computing the pediatric dosage for a child of a given weight. 👶
Our calculator allows you to convert values in mg or μg to a precise volume of the medication, using a wide range of units.
The article below is an essential part of our peds dosing calculator  keep on reading to discover all the necessary medical abbreviations, information on pediatric medication dosing, and tips on how to calculate the pediatric dose on your own.

How to use the pediatric dose calculator?
Pediatric dosage is a complicated matter  we can't deny it. We decided to make things easier for you and explain stepbystep all the actions you need to take to receive the most accurate results.
💡 Our mg per kg dosage calculator works both ways; you may convert medication's weight to volume and the other way around. 

Decide whether your dose is given in mg or μg.
Milligrams (mg) are 1000 times greater unit than micrograms (μg)  1 mg = 1000 μg.

Find out your type of dosage.
Your dose in mg/μg might be given:

per kilogram per day (e.g., mg/kg/day)  the most popular option

per kilogram per dose (e.g., mg/kg/dose)

per day (e.g., mg/day)

per dose (e.g., mg/dose)
The calculator will display the chosen dosage type underneath.
Dosage type has a crucial impact on the value of the dosage!
Only the first two types use the dosage calculator by weight; two latter ones rely on a predetermined amount of medication.

Finally, enter your dose amount in mg or μg.
Doublecheck all the settings  you want to make sure that the pediatric drug dose calculator is computing exactly what you want it to calculate.

Choose the frequency.  check the
. 
Choose the weight of your child and a proper unit.

Enter your drug concentration.
Choose the mass of the drug per given volume of the medication.
The calculator will display the chosen concentration underneath.
💡 Our calculator can also compute the number of tablets needed. To calculate that, enter 1 into the volume field. 💊 
 Yay! Your results are here  it wasn't that hard, was it? 🎉

Dose frequency abbreviations
Dose frequency might be quite misleading since all the abbreviations originate from the Latin language. Here we present a short, useful medical dictionary:
 dQ  once per day
 BID  twice per day
 TID  three times per day
 QID  four times per day
 q4 hr  once every four hours (6 times per day)
 q3 hr  once every three hours (8 times per day)
 q2 hr  once every two hours (12 times per day)
 q1 hr  once every hour (24 times per day)
How do you calculate pediatric doses?
There's one primary dose calculation formula for children:
▪️ mg/μg per kilogram per day
dose (volume) = (dose (mg/μg) * child's weight) / (concentration * frequency)
where:
concentration
is usually given in mg/mLchild's weight
is given in kgfrequency
means the number of times a chosen medication is given per day. E.g., q1 hr frequency has a value of 24.
However, this equation still has to be modified for every other type of dosage! Below, we enumerated all the available pediatric dosage calculations formulas:
▪️ mg/μg per kilogram per dose
dose (volume) = (dose (mg/μg) * child's weight) / concentration
▪️ mg/μg per day
dose (volume) = dose (mg/μg) / (concentration * frequency)
▪️ mg/μg per day
dose (volume) = dose (mg/μg) / concentration

Child dose calculations examples
Our baby has a fever! 🤒🌡️👶
Still not sure how to calculate pediatric doses? We're going to focus on an mg/kg/day formula since it's the most complex one. Carefully follow the example below:
 We bought some paracetamol to lower the fever  its container states that this syrup's concentration is equal to 120 mg /5 mL. Our prescribed peds dose is 10 mg/kg. Our kid's 4.5 years old and weights 20 kg. We need two doses of paracetamol per day.
How much mL of paracetamol syrup do we need per day?
Let's use the following formula:
dose (volume) = (dose (mg/μg) * child's weight) / (concentration * frequency)
First, let's boil down the concentration:
120 mg/5 mL / 5
= 24 mg / 1 mL
= 24 mg/mL
Then come back to the equation itself:
dose (volume) = (10 mg/kg * 10 kg) / (24 mg/mL * 2)
dose (volume) = 100 mg / 48 mg/mL
dose (volume) = 2.083 ≈ 2.1 mL
 we need 2.1 mL of paracetamol per dose, twice per day.
Yay, we got it! You're becoming the true pediatric dose master.
