<p>Ground coffee density is 365 kg/m³, so it's 2,72 times less dense than water, therefore 5 ml of ground coffee means 1.83 g, which equals to 22 mg of caffeine if the concentration is 1,2%.</p>

<p>4 flat tsp of mixed blend of coffee from multiple sources weighted 3g. The powder was not packed/compressed at all.</p>
<p>1 packed tsp of the same coffe weighted also 3g.</p>
<p>My digital kitchen scale is able to measure only by 1g steps. I did multiple measurements +/- 1 tsp, at the end I concluded 1tsp of this particular blend is 1.67g.
Therefore 1.2% of it  is 20mg coffein.</p>

That means you get around 5g of ground coffee in one teaspoon, which totals around 0,06g or 60mg of caffeine.

However please consider that teaspoons and spoons are in general a [terrible unit of measurement](https://en.wikipedia.org/wiki/Teaspoon#Metric_teaspoon) for various reasons.

4 flat tsp of mixed blend of coffee from multiple sources weighted 3g. The powder was not packed/compressed at all.

1 packed tsp of the same coffe weighted also 3g.

My digital kitchen scale is able to measure only by 1g steps. I did multiple measurements +/- 1 tsp, at the end I concluded 1tsp of this particular blend is 1.67g.
Therefore 1.2% of it is 20mg coffein.
