Step 0: READ the Instructions.

• STOP! Did you read all the instructions? If not:
• Read the instructions, now!

Step 1: calculate volume of a ROUND or RECTANGULAR kiddie pool.

• Enter your pool's dimensions (maximum distance across) in inches.
• If you need to, you can use the conversion calculator to convert a measurement of, say, 4' 6" to 54".
  
• Enter your pool's depth at the fill line.
  
• Press the calculate buttons, to figure the volume in gallons, or if you have an odd shaped pool, enter the gallons manually in the "Entered gallons" box.

Step 2: calculate kiddie pool doses.

• If you didn't calculate your pool's volume, enter it in the "Entered gallons" box.
• Press the "calculate doses" button. The bottom section will display doses for your pools in cups, tablespoons, OR teaspoons. Use which ever measurement is appropriate . . . but do not add doses. That is, either use, for example, 0.5 cups or 8 Tablespoons, but not both.
• If you need to recalculate, press the "Oops!" button, and start over.

Caution:
This calculator is not yet fully tested: use at your own risk! I don't guarantee anything, except that there might be errors. And remember, this calculator uses American units of weight, length, and volume.

 depth: in.

enter depth at the water line,
not at the top edge of the pool

Important:
The doses given above are approximate: accurate doses would be in pounds or grams, but since most pool owners don't use a scale to weigh their chemicals, I've used approximate volume measurements. TEST after dosing with bleach or dichlor, to verify results. Borax and algaecide doses are close enough.
