平均水深怎么求？

把浅端和深端水深相加除以二。这适用于坡度均匀的池底；若有较长平底再突然下沉，应分区计算再相加。

为什么必须知道泳池容积？

因为所有药剂投放量都按容积给出，通常以每一万加仑为单位。估错容积就意味着氯和酸长期投多或投少。

一立方英尺等于多少加仑？

一立方英尺约合 7.48 美制加仑。反过来，一加仑约为 0.1337 立方英尺。

水位变化会影响容积吗？

会，而且比想象中明显。9.7 × 4.9 米的泳池水位下降 7 厘米就少了约 950 加仑，足以让投药量出现偏差。

异形泳池怎么估算？

按平均长宽当作椭圆形计算，再减去约 10%。用于投药足够准确；加热设备选型请向施工方索取设计容积。

参考资料

Measure what the tool asks for
This calculator works from 长度 in ft, 宽度 in ft and 直径（仅圆形） in ft. Measure the finished area you are covering, not the material — an estimate is only as good as the dimensions you feed it.
What it does with those numbers
平均水深 = (浅端 + 深端) ÷ 2 · 加仑 = ft³ × 7.481 Every figure on the page comes out of that one expression, so you can check it by hand.
Choosing a 泳池形状
The 泳池形状 changes the result, so pick the one that matches what you are actually buying rather than leaving the default.
Where the numbers come from
The constants are taken from CDC Model Aquatic Health Code — Pool operation and water quality and Pool & Hot Tub Alliance — Water chemistry standards, linked in full below. If a figure here disagrees with your supplier's spec sheet, use the spec sheet — it describes the product you are buying.
What this will not tell you
This is a material takeoff, not a bid. It does not price labour, permits, delivery, equipment hire or site preparation, and it assumes a straightforward layout. Complex cuts, difficult access and awkward shapes all cost more than the geometry suggests.

用长乘宽乘平均水深得立方英尺，再乘以 7.48。9.7 × 4.9 米、平均水深 1.4 米的泳池约容纳 17,240 加仑。
