Dear convert-me.com forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

Converting tsp/gal to ppm

Please convert 1/4 tsp per 2 gallons of water into ppm.
1/2 tsp per 2 gallons of water into ppm
1 tsp per 2 gallons of water into ppm
and 1 tblspn per 1 gallon of water into ppm.

Thanks! (This is for chlorine concentrations).

Ppm can be stated on a weight, volume, or mole fraction basis. The results are generally different according to which basis is used.

We only have info to do by volume, but a solid that dissolves in a liquid would probably be stated on weight/weight basis. Never mind.

2 gallons is 256 fl oz
1 teaspoon is 1/6 fl oz, 1/4 teaspoon is 1/24 fl oz

So 1/4 teaspoon in 2 gallons is 1/24 floz / 256 fl oz or 0.000163, or 163 ppm.

1/2 teaspoon is 326, and 1 teaspoon is 651. That's in the 2 gallon bucket, not in the swimming pool.

Thank you! This is for sanitizing solutions for temporary food facilities. They are required to have 100 ppm chlorine solutions for sanitizing. It is easier for them to understand teaspoons-per-gallon than it is to understand parts-per-million.
