To calculate the capacity of a water tank in gallons, you need to know the tank’s dimensions and shape. Here’s how to calculate it for a rectangular or cylindrical tank:
For a Rectangular Tank:
1. Measure the length (L), width (W), and height (H) of the tank in feet.
2. Multiply these dimensions together to find the volume in cubic feet: V = L x W x H.
3. Convert the volume to gallons by multiplying by 7.48052 (since 1 cubic foot equals approximately 7.48052 gallons): Capacity (in gallons) = V x 7.48052.
For a Cylindrical Tank:
1. Measure the radius (r) and height (H) of the tank in feet.
2. Calculate the volume of the cylinder in cubic feet using the formula: V = π x r^2 x H, where π (pi) is approximately 3.14159.
3. Convert the volume to gallons by multiplying by 7.48052: Capacity (in gallons) = V x 7.48052.
Keep in mind that these calculations assume the tank is full to its maximum capacity. If the tank is not filled to the top, you can adjust the calculation accordingly.
Now first try to understand estimation of water requirement based on Number of persons and per capita demand, it not depend on how size is home. Do you think a huge quantity of water used for flush of toilets, taking showers and baths, washing your cloths and utensil, cocking food, drinking and others domestic purpose.
Generally capacity of water tank is volume of water that tank can hold, volume measured in cubic feet, cubic metre, litres and gallons. In United States, capacity of water tank measured in gallons, in this article we try to know about how to calculate water tank capacity in gallons.
The volume of water tank in cubic feet is equal to the area of tank multiply by their height, such as volume = Area × height, the capacity of water tank in gallons is equal to the volume in cubic feet multiply by 7.5 gallons per cubic feet.
How to calculate water tank capacity in gallons
Regarding this, how to calculate water tank capacity in gallons, generally in United States, water tank capacity measured in gallons, you can calculate water tank capacity by multiplying volume of water tank in cubic feet by 7.5 gallons per cubic feet, such as capacity = Volume in CF × 7.5 gallons.
To calculate rectangular and round water tank capacity in gallons, multiply volume of water tank in cubic feet by 7.5 gallons per cubic feet. Formula for capacity of water tank in gallons = Volume of water tank in cubic feet × 7.5 gallons. For example, if volume of rectangular water tank is 50 cubic feet, then capacity of water tank = 50×7.5 = 375 gallons.
Rectangular Water Tank Capacity in gallons
To calculate the total capacity and filled volume of rectangular water tank in gallons, multiply the volume of rectangular water tank in cubic feet by 7.5 gallons per cubic feet. Formula for capacity of rectangular water tank in gallons = Volume of water tank in cubic feet × 7.5 gallons. For example, if volume of rectangular water tank is 350 cubic feet, then capacity of rectangular water tank = 350×7.5 = 2,625 gallons.
To determine the capacity rectangular water tank in gallons, we can proceeds in following steps:-
● Measures the each dimension of rectangular water tank, suppose a tank 10 feet long by 6 feet wide by 5 feet height
● Calculate the area of rectangular tank by multiplying Length and width, such as Area = length × width, 10 ft × 6 ft = 60 sq ft
● Calculate volume of rectangular tank by multiplying area and height, such as volume = area × height, 60 sq ft × 5 ft = 300 cubic feet
Formula for capacity of rectangular water tank in gallons = Volume of water tank in cubic feet × 7.5 gallons. For example, if volume of rectangular water tank is 300 cubic feet, then capacity of water tank = 300×7.5 = 2250 gallons.

Circular Water Tank Capacity in gallons
To find the capacity of circular water tank in gallons, multiply volume of round or circular water tank in cubic feet by 7.5 gallons per cubic feet. Formula for capacity of round water tank in gallons = Volume of water tank in cubic feet × 7.5 gallons. For example, if volume of round water tank is 100 cubic feet, then capacity of water tank = 100×7.5 = 750 gallons.
To determine the capacity round water tank in gallons, we can proceeds in following steps:-
● Measures the each dimension of circular water tank, suppose a tank 5 feet diameter by 6 feet height
● Calculate the area of circular tank by multiplying the square of diameter by 3.14 (π) divided by 4, such as Area = π D^2/4, 3.14 × 5×5/4 = 19.625 sq ft
● Calculate volume of circular tank by multiplying area and height, such as volume = area × height, 19.625 sq ft × 6 ft = 118 CF
● To determine the capacity of circular water tank in gallon, you multiply volume of tank in cubic feet by 7.5 gallons per cubic feet, capacity = volume in CF × 7.5 gallons, capacity = 118 × 7.5 = 885 gallons, this is capacity of circular water tank in gallons.
Conclusions:-
To calculate rectangular and round water tank capacity in gallons, multiply volume of water tank in cubic feet by 7.5 gallons per cubic feet. Formula for capacity of water tank = Volume of water tank in cubic feet × 7.5 gallons.
