## Applications

Use this length x diameter calculator to determine the volume in the following applications:

- Vertical cylindrical container storage capacity from the height and diameter of the container
- Horizontal cylindrical tank storage capacity from the length and height of the tank
- Internal volume of tubing to determine flow capacity from the length and internal diameter of the the tube
- Amount of water contained within a well or borehole from the water depth and hole diameter
- The volume of metal bars or cables from the length and diameter, which can then be used to calculate the weight if the material density is known
- Quantity of water that can be stored in a circular water storage tank

## User Guide

This tool will calculate the volume of a cylindrical shaped object from the dimensions of length and diameter. No conversion needed, since length, diameter and volume units can be selected independently, so this calculator allows you to use any mixture of measurement units.

Once the measurements have been entered for length and diameter, the calculated volume will be shown in the answer box. Also a graphic of the cylindrical shape with marked dimensions will be drawn which will redraw each time any of the entered inputs or selected units are changed.

### Formulas

The formulae used by this calculator to calculate the volume of a cylindrical shaped object is:

r = ø/2

V = L · π · r²

V = L · π · (ø/2)²

#### Symbols

- V = Volume
- L = Length
- ø = Diameter
- r = Radius
- π = Pi = 3.14159…

### Volume Dimensions – Length & Diameter

Enter the measurements of length and diameter for the object you are calculating, and select the appropriate units for each measurement value entered.

The following conversion factors in metres (m) are used for converting length and diameter into different units:

- nanometre (nm) – 0.000000001 m
- micrometre (µm) – 0.000001 m
- millimetre (mm) – 0.001 m
- centimetre (cm) – 0.01 m
- inch (in) – 0.0254 m
- foot (ft) – 0.3048 m
- yard (yd) – 0.9144 m
- metre (m) – 1 m
- kilometre (km) – 1,000 m
- mile (mi) – 1,609.344 m
- nautical mile (nmi) – 1,852 m

### Volume Calculation

This is the calculated volume of the cylindrical object, which this tool derives by entering the values for length and diameter into the formula described above. you can calculate the volume in different units by changing the unit selection below the result.
