You are standing in front of a tin trying to work out whether to buy two or four, and every answer online is vague. Here is the arithmetic, and the method so you can do it for whatever tin you end up holding.
The short version. An 800 g tin of HiPP 1 holds about 186 scoops. At one 4.3 g scoop per 30 ml, that is roughly 5.6 litres of prepared formula. For a newborn taking 60 ml, that is about 93 bottles and somewhere around twelve days of feeds. For a six-month-old on 210 ml, about 26 bottles and around a week.
The method, in one line
Divide the weight of the tin by the weight of one scoop. That gives you the number of scoops. Multiply by the millilitres each scoop makes. That is your total volume.
For HiPP 1: 800 g ÷ 4.3 g = 186 scoops. 186 × 30 ml = about 5,580 ml.
Both numbers you need are printed on your tin. The scoop weight and the water-per-scoop are in the dosing line — on HiPP 1 it reads “Gebruik altijd 1 maatlepel (4,3 g) voor 30 ml water”, always use one scoop of 4.3 g per 30 ml of water.
This is worth doing yourself rather than trusting a chart, because scoop weights differ between brands and between stages of the same brand. Health Canada makes the same point when it warns that some formulas are one scoop per 30 ml and others one per 60 ml, and that getting it wrong affects how much nutrition and water your baby gets.
What that means in bottles, by age
Using the feeding table printed on the HiPP 1 tin, and the 5.6 litres above:
| Age | Water per bottle | Bottles per day | Bottles from one 800 g tin | Roughly how long |
|---|---|---|---|---|
| 1st–2nd week | 60 ml | 7–8 | ~93 | ~12 days |
| 3–4 weeks | 90 ml | 5–7 | ~62 | ~10 days |
| 5–8 weeks | 120 ml | 5–6 | ~46 | ~8 days |
| 3–4 months | 150 ml | 4–5 | ~37 | ~8 days |
| 5 months | 180 ml | 4 | ~31 | ~8 days |
| from 6 months | 210 ml | 4 | ~26 | ~7 days |
Three things about this table. The volumes are water, which is how the tin’s own table states them — the finished bottle is slightly more once the powder dissolves. The bottle sizes and daily counts are the tin’s guide values, not a rule; the same panel says your child does not have to finish the bottle. And the “how long” column assumes formula only — if your baby is also breastfed, or past six months and eating solids, a tin stretches further.
Why a tin does not last much longer as they grow
It looks like it should. Bottles get bigger but there are fewer of them, and those two changes nearly cancel out. A newborn drinks around 450 ml a day across seven or eight feeds; a six-month-old drinks around 840 ml across four. The bigger baby gets through a tin faster, not slower.
Which is the opposite of what most people assume when they are buying ahead.
How much to actually buy
Working from the figures above: roughly two to three 800 g tins a month in the first weeks, rising to four or five a month by six months if you are feeding formula only. A tin lasts about twelve days at the start and about a week by six months, so a month takes two and a half tins early on and closer to four and a half later.
If your baby is combination fed, or eating solids after six months, you will need fewer. Those figures are the ceiling, not the forecast.
Before you buy a season’s worth, two things are worth knowing. An opened tin of HiPP keeps three weeks, so stockpiling only helps if the tins stay sealed. And a formula that suits your baby at four weeks is the one to buy in quantity — buying four tins before they have tried one is a bet, not a saving.
Our smallest size is a two-pack and four-packs ship free, so the sensible order before a birth is usually a two-pack. If the formula turns out not to suit your baby, our satisfaction guarantee means we will help you find one that does.
Common questions
How many scoops are in an 800 g tin of formula?
About 186, on HiPP 1, where one scoop is 4.3 g. Divide your tin’s weight by the scoop weight printed on the pack to get the figure for any other tin.
How many bottles does an 800 g tin make?
About 5.6 litres of prepared formula in total. How many bottles that is depends on the size of the bottle: roughly 93 at 60 ml, about 26 at 210 ml.
How many scoops are in a 400 g tin?
About 93, at 4.3 g per scoop — half of an 800 g tin.
How long does a tin of formula last?
Around twelve days for a newborn feeding formula only, and around a week by six months. Less if your baby is a big feeder, longer if you are combination feeding.
How many tins will I need in a month?
Two to three in the first weeks, four or five a month by six months if you are feeding formula only. Fewer if you are combination feeding or your baby has started solids.
Can I use a scoop from another tin to measure?
No. Scoop weights differ between brands and between stages, and the tin tells you to use only the scoop inside it.
Does the prepared formula measure exactly 30 ml per scoop?
Slightly more — the powder adds a little volume to the water. The difference is small enough to ignore for planning, and you should still measure the water, not the finished bottle.
