Spike's Calculators

Calculate the amount of liquid in a partially filled rectangle tank or container. This calculator uses feet 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 rectangle tank in feet and or inches
- the length of the tank in feet and or inches
- the width of the tank in 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 = H*W*L where V is the volume of the rectangle H the tanks height W the width of the rectangle tank L the length of the tank## Conversions
