Mg per pouch vs mg per gram: reading nicotine pouch strength

Why an Iceberg tin can say 150mg/g and still be a 50mg pouch, how to convert one figure to the other, and which brands use which.

Quick answer: Mg per pouch is the nicotine in one pouch. Mg per gram is the nicotine in one gram of pouch material, and a pouch weighs less than a gram, so the per-gram figure is always higher. To convert, multiply mg per gram by the pouch weight in grams. We list every tin in mg per pouch so they compare on one scale.

Mg per pouch is the amount of nicotine in one pouch. Mg per gram is the amount of nicotine in one gram of the material inside the pouch. A pouch weighs less than a gram, so a per-gram figure is always higher than the per-pouch figure for the same tin, often by three or four times. To convert, multiply the mg per gram by the pouch weight in grams. Every tin on this site is listed in mg per pouch so the whole range sits on one scale.

Two units, one tin

Most brands print mg per pouch. ZYN, VELO, Nordic Spirit, Killa and Pablo all do, and so do the smaller UK brands. When a VELO tin says 10mg, each pouch in it holds 10mg of nicotine.

A smaller number of brands, mostly those with roots in Swedish snus, print mg per gram instead. Iceberg does this on several of its lines. Siberia prints 43mg/g on its tins. It is the same convention Swedish snus has used for decades, where tins carry a per-gram figure because loose snus has no fixed portion size.

Both are honest numbers. The trouble starts when you put a 43mg/g tin next to a 16.5mg tin and assume the first is nearly three times stronger. It is not, because you are comparing nicotine concentration with nicotine quantity.

The conversion

The sum is short.

Mg per pouch = mg per gram × pouch weight in grams

Slim pouches from the big brands tend to weigh somewhere around half a gram, and minis less than that. Brands rarely print the pouch weight on the tin, so you often cannot do the sum exactly from the label alone. That is why we convert for you and list a per-pouch figure for every tin.

Label says	If a pouch weighs 0.3g	If a pouch weighs 0.5g	If a pouch weighs 0.7g
20mg/g	6mg	10mg	14mg
43mg/g	13mg	21.5mg	30mg
50mg/g	15mg	25mg	35mg
100mg/g	30mg	50mg	70mg
150mg/g	45mg	75mg	105mg

The rows show how much the pouch weight matters. The same 43mg/g label gives 13mg in a small pouch and 30mg in a large one. A per-gram number without a pouch weight is only half the information.

Two worked examples from the range

Siberia. The tin says 43mg/g. We list Siberia at 33mg per pouch, and that figure is the same across the All White, Slim, Super Slim and Ultra Slim versions. Working backwards, 33 divided by 43 gives a pouch weight of roughly 0.77g, which fits a full-size snus-style pouch. So a Siberia is X-Strong, but it is a 33mg pouch rather than a 43mg one. Still a very strong tin, and the Siberia range is best left to ex-snus users.

Iceberg. Iceberg's labels quote nicotine per gram and the figures run high, with its strongest lines printed at 150mg/g. We list Iceberg in two tiers, 20mg per pouch for the standard line (Iceberg Black, Cool Mint, Cola, Watermelon and others) and 50mg per pouch for the stronger line (Double Mint, Sour Berries, Emerald and others). A 150mg/g label on a 50mg pouch means a pouch weighing about a third of a gram, which is a small, dense pouch. The Iceberg range shows both tiers with the per-pouch figure.

Why per-gram labels overstate strength

Three reasons the per-gram habit misleads.

Pouches are lighter than a gram, so the per-gram number is always bigger than the dose you get. On a 0.5g pouch it is double.
The number lands next to per-pouch figures on the same shelf. A 43mg/g tin next to a 16.5mg Killa looks like the obvious choice for a heavy user, when the real gap is 33mg to 16.5mg.
Brands do not always say which unit they are using. Some tins say "mg/g" clearly. Others say "43mg" with the "/g" in tiny print, or on the base.

None of this means per-gram brands are weak. Siberia at 33mg and Iceberg at 50mg are among the strongest tins on the site. It means the label number is not the number to compare.

How to read the label in a shop

Find the strength figure. If it says mg/g, it is a concentration, not a dose.
If the tin also prints a pouch weight or a total nicotine per tin, divide total nicotine by the pouch count for the per-pouch figure.
If it does not, assume a slim pouch is roughly half a gram and halve the per-gram figure for a rough per-pouch estimate. Treat it as a guess, not a fact.
Check it against the mg per pouch we list, which is the figure we have converted for every tin.

For what to do with the per-pouch number once you have it, see the nicotine pouch strength guide. The strength browse pages sort every brand into the same four bands using per-pouch figures, so Iceberg, Siberia and Killa all land where they belong.

Frequently asked questions

Is 43mg/g the same as 43mg?

No. 43mg/g means 43mg of nicotine for every gram of pouch material. A pouch weighs less than a gram, so the actual nicotine per pouch is lower. Siberia prints 43mg/g and works out at 33mg per pouch.

Why does Iceberg say 150mg/g?

Iceberg follows the Swedish habit of labelling by concentration. Its pouches are small and dense, so a high per-gram figure converts to 50mg per pouch on the strong line and 20mg on the standard line.

Which figure should I use to pick a strength?

Mg per pouch, always. It is the figure our bands use, it is what most brands print, and it tells you what one pouch holds. Per-gram figures only help if you also know the pouch weight.

Do any UK brands print mg per gram?

Mostly it is brands with Swedish or Baltic roots: Iceberg and Siberia are the two you will meet most often. ZYN, VELO, Nordic Spirit, Pablo, Killa and the smaller UK ranges print mg per pouch.
