Cylinder Volume Formula:
From: | To: |
The cylinder volume formula calculates the volume of a cylinder in US gallons based on its radius and height. This is particularly useful for determining liquid capacity in cylindrical containers.
The calculator uses the cylinder volume formula:
Where:
Explanation: The formula calculates the volume in cubic inches (πr²h) and converts it to US gallons by dividing by 231 (since 1 US gallon = 231 cubic inches).
Details: Accurate volume calculation is essential for determining liquid capacity in tanks, pipes, and other cylindrical containers in industries like manufacturing, agriculture, and chemical processing.
Tips: Enter radius and height in inches. Both values must be positive numbers. The calculator will automatically compute the volume in US gallons.
Q1: Why divide by 231?
A: 231 cubic inches equals 1 US gallon, so this conversion factor gives the volume in standard US gallons.
Q2: Can I use this for metric measurements?
A: No, this calculator is specifically for inches to US gallons. For metric, you would need different conversion factors.
Q3: Does this work for partially filled cylinders?
A: This calculates total volume. For partial fills, you would need to know the fill height and use that as your height value.
Q4: How accurate is this calculation?
A: It's mathematically precise for perfect cylinders. Real-world containers may have variations in shape that affect actual capacity.
Q5: Can I use diameter instead of radius?
A: Yes, but you would need to divide diameter by 2 first since the formula requires radius.
