Can anyone help me convert teaspoon measurement to grams measurement. Basically I hav a electronic pocket scale (100G/0.01g) and want to dry dose by weighing the marco nutrients.

1/4 Tsp-KN03, into grams
1/16 Tsp-KH2P04 into grams

I also hav K2SO4, Fe+, MGSO4 and i dont know the dose for this.

My tank 20G, high light, high Co2. thanks.

@Dempsey
I used another one that I didn't like very much but that link is great I just used it and I guess I was under dosing a bit in a few areas but my plants are doing fine, I'll up it a bit tho and see how it goes.
Thanks

Not only a target ppm tho you can choose show the result of your dose of 1 gram of KNO3 for example and see what that brings its to. Since you know the target of 10-20 ppm Nitrates you do the math and figure out you need ~3g of KNO3 to meet that requirement.
The calculator makes it pretty easy for you so what else would you need to know?

the last line
"My target is xxx ppm." i ddint know what to put because i didnt know the target No3 was 10-20 ppm. But it's getting clearer now, i'll work within that blue bar.

Ahh well sry then this should help too
N (10-20ppm)
P (0.5-2ppm)
K (10-20ppm)
Ca (10-30ppm)
Mg (2-5ppm)
Fe (.1ppm).

edit:
this is not exact, of course, you have to mess around with it to see what works best for your setup.
I've also read different ranges from different people so yeah ... good luck
