Cylinder Tank Horizontal

Calculate a horizontal cylinder-shaped tank's volume, capacity, and surface area.
This calculator uses inches for measurements.

Approximate weight of Fuel or Water
```one US gallon of water = 8.34 pounds.
one US gallon of diesel fuel = 7.1 pounds
one US gallon of gas = 6 pounds
```
`Note: measurement used in the calculation is the  diameter length, not the radius length! `

Calculator

1. enter the length of the tank in inches
2. the diameter in inches
3. the weight of the liquid in pounds per US gallon

Results

1. the volume of the tank in cubic inches
2. volume in cubic feet
3. volume in cubic metres
4. tank capacity in US gallons
5. capacity in Imperial gallons
6. capacity in litres
7. full tank liquid weight based on lbs/gal US
8. the surface area of the tank in square inches
9. the surface area in square feet
10. the surface area in square millimetres
11. the surface area in square metres
Formula
```V=𝝅(D/2)*L
where V is the volume
𝝅 = 3.14159265
D the diameter
L the length of the tank
```
Conversions
```one cubic inch (in³) = 0.00432900432900432 gallons (gal) US
one cubic inch (in³) = 0.00360465014990905 gallons (gal) Imperial
one cubic inch (in³) = 0.016387064 litres (L)
