I’m shocked that nowhere contains the correct answer as I was hoping to save myself a few minutes today.

For Soylent 1.5:

OK 4 servings in one pouch, which is 115g x 4 = 460g

Which incidentally it says on the box.

I measured out the entire bag today, half cup at a time with a baking set. Then I did another bag just to make sure.

There are roughly 2.5 cups of powder to one bag.

Actually there was some residuals both times so its probably closer to 2.6 cups in a bag.

This means each cup is 800 calories (2000/2.5)

I needed a 1200 calorie day today because I’m having dinner with a friend so that’s 1.5 cups.

Since each official scoop is 250cal, that means there are 3.2 scoops per cup.

Sadly (or thankfully?) this answer will be redundant in a few more days.
