Here is a small labelling magic trick. One can can look twice as strong as the can beside it while holding less nicotine per pouch. Nobody has misprinted anything. The two cans are quoting different numbers, and the bigger-looking one is quoting concentration.
It is the most common confusion in the category, so it gets its own page. The difference, the formula, and the formula worked end to end on cans on sale today. As everywhere on Snus Watch, this is written for adult nicotine users: 18 and over, and 21 and over in the US.
What is the difference between mg per gram and mg per pouch?
Mg per gram counts nicotine against the weight of the filling. Think of it as the strength of the mix itself, before anyone portions it into pouches.
Mg per pouch counts what sits inside a single finished pouch. Same mix, bigger pouch, bigger total. The portion size is part of the number.
That is the whole difference. One number describes the recipe, and the other describes the serving.
How do you convert mg per gram to mg per pouch?
The formula fits on one line:
mg per pouch = mg per gram × pouch weight (g)
Every term is findable. The mg per gram is printed on the can or the product page. The pouch weight rarely gets its own line. But net weight and pouch count are standard product data, and net weight divided by count is the pouch weight, filling and all.
Pouch weights are not standardised either. A slim can at 10 g net over 20 pouches runs 0.5 g a pouch. A fuller slim can at 14.3 g over 20 pouches runs about 0.7 g a pouch. That gap is exactly why mg per gram alone cannot compare two cans.
What does the conversion look like on real cans?
| Can | Printed mg/g | Pouch weight | Maths | Mg per pouch |
|---|---|---|---|---|
| Greatest Cold Dry Easy (Slim) | 8 | 0.5 g (10 g net, 20 pouches) | 8 × 0.5 | 4 |
| On! Plus Mint Strong (Slim) | 12.6 | About 0.7 g (14.3 g net, 20 pouches) | 12.6 × 0.7 | 9 |
| Haypp's published worked example | 15 | 0.7 g | 15 × 0.7 | 10.5 |
Both real cans land exactly on the mg per pouch figure the retailer prints beside the mg per gram. That is the sanity check: the formula above is the one the industry itself uses.
The Greatest can is the tidy demonstration. Its 8 mg/g sounds mid-table, yet each slim pouch is light at half a gram, so the total per pouch is 4 mg. The On! can runs the other way: a bigger number per gram and a heavier pouch, landing at a 9 mg total. Concentration flatters the light pouch and short-changes the heavy one.
The extreme version is the big front-of-can number. Planet of the Vapes points out that a can shouting 50 mg is quoting mg per gram, and the pouch inside carries roughly 30 mg. Fifty was never the serving. It was the recipe.
Why do labels print it both ways?
Mg per gram is the number the filling is manufactured to, so it follows the product through production and across markets. Mg per pouch is the number a shelf needs, so US cans lead with it, and retailers such as Haypp standardise on it for comparison.
Add dots and brand strength words, which exist so a range reads at a glance, and one can ends up fluent in three dialects. The strength guide decodes all three; this page is just the arithmetic between the first two.
Which number should you compare?
Mg per pouch, converted wherever the can withholds it. It is the only version of the number that describes the same thing on every can: one pouch, total nicotine, no portion-size trick.
If a shop's table and your maths disagree by a decimal, trust the direction rather than the decimal. Retailers round pouch weights and totals differently. Where a converted figure and a printed figure part ways in our own tables, we say so instead of quietly choosing one.
Keep going from here: the guides hub collects the label decodes, and the blog tracks new ranges as brands print them.
FAQ
Can you convert mg per gram without knowing the pouch weight?
No. The weight is the multiplier, so without it the conversion has a hole in it. Use the net weight and pouch count from the product data, which gives you the average pouch weight in one division.
Why does the same product show different numbers in different shops?
Usually because one shop lists mg per gram and the other lists mg per pouch, and occasionally because one of them rounds its figures. Check which unit the column header names before comparing anything.
Does a mini pouch at the same mg per gram hold less nicotine?
Yes. Same concentration, less filling per pouch, smaller total. That portion-size effect is exactly what the formula exists to expose.
Is the pouch weight printed on the can?
Rarely as its own line. Net weight and pouch count are printed. Dividing one by the other gives the working pouch weight used in the table above.
Which number do the dots on a can correspond to?
Neither, directly. Dots are set by each brand against its own range, and mg per pouch is the reliable cross-check. The strength guide maps the VELO ladder rung by rung.
