# Cylindrical or Rectangular Tank Capacity Calculator

getcalc.com's **Fuel or Water Tank Capacity Calculator** is an online basic geometry tool & formulas to measure the capacity of cylindrical or rectangular tank, in US customary & metric (SI) units (Gallons & Liters).

## Steps to Find Capacity of a Rectangular Tank

The step by step workout for how to find what is the capacity of a rectangular tank.__Workout :__

step 1 Address the formula, input parameters and values

Length = 10 in

Width = 5 in

Height = 8 in

step 2 Input Conversion for length, width, height

Convert in to m all input values

Length = 10 x 0.0254 = 0.254 m

Width = 5 x 0.0254 = 0.127 m

Height = 8 x 0.0254 = 0.2032 m

step 3 Apply the values in volume formula

Volume V = length x width x height

= 0.254 x 0.127 x 0.2032 m³

Volume = 0.0066 m³

step 4 Capacity of Rectangular Tank in Liters

Capacity in Liters = (Volume in cubic meter) x 1000

= 0.0066 x 1000

Capacity in liters = 6.5548

step 5 Capacity of Rectangular Tank in Gallons

Capacity in Gallons = (Capacity in liters) / 3.7854

= 6.5548/3.7854

Capacity in Gallons = 1.7316

## Definition & Formulas

**Tank Capacity** is a measure of how much maximum Gallons or Liters of fuel or water a cylindrical or rectangular tank can contain, based on its volume space.
