Spike's Calculators

Calculate the amount of liquid in a partially filled flat horizontal oval tank or container. The horizontal oval tank here has a rectangle-like center with semi-circular ends. This calculator uses centimetres for measurements.

one US gallon of water = 8.34 pounds. one US gallon of diesel fuel = 7.1 pounds one US gallon of gas = 6 pounds

- enter the height of the flat horizontal oval tank n feet and or inches
- the width of the tank in feet and or inches
- the length of the tank n feet and or inches
- the depth of the liquid inside the tank in feet and or inches
- the weight of the liquid in pounds per US gallons

- the volume of the tank in cubic feet
- the volume of the tank in cubic inches
- the volume of the tank in cubic metres
- the total amount of liquid the tank can hold in US gallons
- amount of liquid the tank can hold in litres
- the amount of liquid inside the tank in cubic feet
- the amount of liquid inside the tank in US gallons
- the amount of liquid inside the tank in Imperial gallons
- the amount of liquid inside the tank in litres
- the amount of liquid inside the tank in hectolitres
- the weight of the liquid inside the tank based on lbs/gal US
- the amount of liquid it will take to fill this tank in US gallons

V = 0.5r²(Y-sin(Y))L+d(W-H) where V is the volume r half the tanks height Y=2cos^{-}¹(r-d)/d d the depth of the liquid inside the tank W the width of the tank H the tanks height## Conversions
