How Many Gallons in an 18 X 48 Pool

Swimming pools are a great addition to any backyard, providing a refreshing oasis during the hot summer months. If you are considering installing an above-ground pool, you may be wondering how many gallons of water it can hold. In this article, we will explore the water capacity of an 18 X 48 pool, along with some commonly asked questions related to pool sizes.

An 18 X 48 pool refers to the dimensions of the pool, with 18 feet being the diameter and 48 inches being the height. To determine how many gallons of water the pool can hold, you can use a simple formula. The volume of a cylinder (the shape of the pool) is calculated by multiplying the area of the base (πr²) by the height (h).

For an 18-foot diameter pool, the radius (r) would be half of the diameter, which is 9 feet or 108 inches. Using this information, we can calculate the area of the base as follows: π(108)² = 36,691.2 square inches.

Next, we convert the height from inches to feet by dividing it by 12: 48 inches ÷ 12 = 4 feet.

Multiplying the area of the base by the height, we find that the volume of the pool is 36,691.2 square inches × 4 feet = 146,764.8 cubic inches.

To convert cubic inches to gallons, we divide by 231 (since there are 231 cubic inches in a gallon): 146,764.8 cubic inches ÷ 231 = 635.9 gallons. Therefore, an 18 X 48 pool can hold approximately 636 gallons of water.

Now, let’s address some common questions related to pool sizes:
