1. What is the Diesel Fuel Tank Size Calculator?

The Diesel Fuel Tank Size Calculator estimates the volume of a rectangular fuel tank in gallons based on its dimensions. This calculation is essential for fuel storage planning, capacity verification, and inventory management.

2. How Does the Calculator Work?

The calculator uses the volume equation:

Where:

• \( Length \) — Tank length in inches
• \( Width \) — Tank width in inches
• \( Height \) — Tank height in inches
• 231 — Conversion factor (cubic inches to gallons)

Explanation: The equation calculates the tank's cubic volume then converts it to gallons (since 1 gallon = 231 cubic inches).

3. Importance of Tank Volume Calculation

Details: Accurate volume calculation is crucial for proper fuel storage planning, compliance with regulations, and preventing overfilling or underutilization of tank capacity.

4. Using the Calculator

Tips: Measure the internal dimensions of your tank in inches. For cylindrical tanks, use different formulas. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 231?
A: 231 cubic inches equals 1 US liquid gallon, which is the standard conversion factor.

Q2: Does this work for cylindrical tanks?
A: No, this calculator is for rectangular tanks only. Cylindrical tanks require π × radius² × height.

Q3: Should I measure internal or external dimensions?
A: Always measure internal dimensions for accurate volume calculation, accounting for tank wall thickness.

Q4: How accurate is this calculation?
A: It provides theoretical maximum volume. Actual usable volume may be less due to tank design, baffles, or fill limits.

Q5: Can this be used for other liquids?
A: Yes, the volume calculation works for any liquid, though weight will vary by density.
