Formula Volume per Kilogram
For the first months the reference is 150 mL per kilogram a day. At 5.2 kg that is 780 mL, or 130 mL across six feeds. Standard formula holds about 67 kcal per 100 mL.

Formula
Daily milk = Weight (kg) × Formula per kg
Babies vary, and hunger cues come before arithmetic. If weight climbs along the growth curve, the volume is right.

Frequently asked questions
Q. How is Formula Volume per Kilogram calculated?
Daily milk = Weight (kg) × Formula per kg — For the first months the reference is 150 mL per kilogram a day. At 5.2 kg that is 780 mL, or 130 mL across six feeds. Standard formula holds about 67 kcal per 100 mL.
Q. Can you walk through an example?
With Weight (kg) 5.2kg, Formula per kg 150mL, Feeds per day 6, the answer is Per feed 130mL.
Q. What do I need to enter?
Enter Weight (kg), Formula per kg, Feeds per day. The result recalculates as you type, and an empty box counts as zero.
Q. How much does the answer move if I change a number?
Changing only Weight (kg) (kg) moves the answer to Weight (kg) (kg) 2.6 → Per feed (mL) 65 and Weight (kg) (kg) 10.4 → Per feed (mL) 260. The table below lays out five steps.
Q. How are the numbers rounded?
Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.
Q. Anything to watch out for?
Babies vary, and hunger cues come before arithmetic. If weight climbs along the growth curve, the volume is right.
