If you need water cost (for this round pool), water cost (for this oval pool) and pool volume and you already have depth, depth1, depth2, diameter (length), water price and width, this calculator does the substitution for you. It suits a quick check, a homework answer you want to confirm, or any figure you need to sanity test.
What Is the Round Pool Volume Calculator?
The round pool volume calculator turns depth, depth1, depth2, diameter (length), water price and width into water cost (for this round pool), water cost (for this oval pool) and pool volume, so you can order the right amount of material the first time.
Material estimates are where projects go over budget. Getting the quantities right before the delivery arrives is worth more than any discount on the order.
How to Measure for the Round Pool Volume
Measure everything in the same unit and take the largest dimension you can reasonably use rather than the average. Formwork, ground conditions and cutting waste all push the real figure above the theoretical one.
Where a plan calls for a specific thickness, check it against local building regulations before you order. The calculator reflects the relationship, not the code.
Allowing for Waste and Errors
Order a little more than the calculation suggests. The gap between the theoretical quantity and what actually arrives on site is normally waste, spillage, over-excavation and uneven grading, and all of it comes out of the same budget.
Write the figures down and compare them with what you actually used on site. That is how you build an estimate you can trust for the next job.
A Worked Example
Working through an example, with depth set to 10, depth1 set to 5, depth2 set to 2, the calculator returns pool volume of 27,488.935719, and pool volume (circle volume above ground) of 78,539.81634, and pool volume (oval volume) of 1,374.446786. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out water cost (for this round pool)?
Enter depth, depth1, depth2, diameter (length), water price and width. The calculator then works through the relationship and reports water cost (for this round pool), water cost (for this oval pool) and pool volume.
What does the round pool volume actually calculate?
It takes depth, depth1, depth2, diameter (length), water price and width and converts them into water cost (for this round pool), water cost (for this oval pool) and pool volume using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter depth?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Is the answer exact?
It is as exact as the formula and the inputs allow. The method itself is the standard one for this problem, so the only sources of error are the figures you enter and the precision you ask for.
Can I use this for a quick estimate as well as a precise answer?
Yes. The calculator is built for quick checks, so round your inputs to a sensible number of significant figures and the result will be just as useful. If you need more precision, keep the same method and add digits to the inputs rather than adjusting the method itself.
